Abstract
Description
Substrate processing device and its operating method
[0001] The present disclosure relates to semiconductor processing equipment, and more specifically, to a substrate processing device that performs temperature control on a semiconductor substrate and an operating method thereof.
[0002] Semiconductor integrated circuits are typically very small and thin silicon chips, but they are comprised of various electronic components. To create a single semiconductor chip, they undergo a variety of manufacturing processes, including photolithography, etching, deposition, reflow, and packaging. Some semiconductor manufacturing processes require a heating process for the substrate, and this is typically achieved by heating the chuck that supports the semiconductor substrate.
[0003] Conventional semiconductor manufacturing processes utilize either a fluid-flowing tube embedded within the chuck or a heat source to heat the chuck. This method, utilizing a fluid-flowing tube embedded within the chuck, can increase the chuck temperature by controlling the flow rate or temperature of the fluid flowing through the tube. Conversely, methods utilizing a heat source embedded within the chuck can increase the chuck temperature by supplying power to the heat source. However, these methods have the disadvantage of requiring a relatively long time to reach the target temperature for semiconductor processing and consuming significant power.
[0004] In this regard, reference may be made to Korean Patent Publication No. 10-2006-0061198A and Korean Patent Publication No. 10-2020-0096747A.

In addition, in FIG. 3b, a plurality of light absorbing parts (340_1, 340_2, …, 340_18) are illustrated as being radially arranged around the support (320), but this merely illustrates an arrangement form according to an embodiment of the present disclosure, and does not limit the arrangement form of the plurality of light absorbing parts (340_1, 340_2, …, 340_18) according to the embodiment of the present disclosure. According to an embodiment of the present disclosure, the plurality of light absorbing parts (340_1, 340_2, …, 340_18) may be arranged in any form for absorbing laser light, and in order to increase laser light absorption efficiency, the area of the plurality of light absorbing parts (340_1, 340_2, …, 340_18) may occupy 50% or more of the area of the support (310).
[0064] FIG. 4 is a flowchart for explaining an operation method of a substrate processing device (110, see FIG. 1) according to one embodiment of the present disclosure.
[0065] In the flowchart illustrated in FIG. 4, steps S401 to S403 may be operations included in a first heating mode of the substrate processing device (110), and steps S404 to S406 may be operations included in a second heating mode of the substrate processing device (110). The first heating mode may refer to an operation mode for raising the temperature of the support chuck (210, see FIG. 2) to a reference temperature and maintaining the reference temperature, and the second heating mode may refer to an operation mode for raising the temperature of the support chuck (210) to a target temperature and maintaining the target temperature. In an embodiment, the reference temperature may be set to be higher than room temperature and lower than the target temperature, and in some embodiments, the reference temperature may refer to a preheating temperature required for the support chuck (210) when performing a process on a substrate (SUB, see FIG. 2). In an embodiment, the reference temperature may be set based on specification information of components constituting the substrate processing device (110). Meanwhile, the target temperature refers to the temperature required to perform a process on the substrate (SUB), and can be set differently depending on the type of process to be performed through the substrate processing device (110).
[0066] In step S401, the substrate processing device (110) according to an embodiment of the present disclosure can supply power to the heating coil (211, see FIG. 2) included in the support chuck (210) under the control of the electronic device (120, see FIG. 1). The amount of power supplied to the heating coil (211) in step S401 may be preset or determined based on semiconductor process recipe information stored in the electronic device (120). For example, the amount of power provided to the heating coil (211) may be determined based on at least a portion of the thermal conductivity information of the support chuck (210) and the heat generation capacity information of the heating coil (211) included in the semiconductor process recipe information, and may be determined by considering the temperature increase efficiency of the support chuck (210) relative to the amount of power supplied. The heating coil (211) may generate heat based on the supplied power, and the heat energy generated by the heat generation of the heating coil (211) may be conducted to the support chuck (210).
[0067] In step S402, the substrate processing device (110) according to the embodiment of the present disclosure can check whether the temperature (T) of the support chuck (210) is less than the reference temperature (T0). If it is confirmed that the temperature (T) of the support chuck (210) is less than the reference temperature (T0), the procedure can return to step S401. On the other hand, if it is confirmed that the temperature (T) of the support chuck (210) has reached the reference temperature (T0), the procedure can proceed to step S403.
[0068] In step S403, the substrate processing device (110) according to the embodiment of the present disclosure can maintain the temperature (T) of the support chuck (210) at the reference temperature (T0). Specifically, the substrate processing device (110) can supply power to the heating coil (211) to maintain the reference temperature (T0) of the support chuck (210) under the control of the electronic device (120), and the amount of power supplied to the heating coil (211) to maintain the reference temperature (T0) of the support chuck (210) can be less than or equal to the amount of power supplied to the heating coil (211) in step S401. While the support chuck (210) maintains the reference temperature (T0), a substrate (SUB) can be placed on one surface of the support chuck (210). Thermal energy of the support chuck (210) can be transferred to the substrate (SUB). In an embodiment, the substrate processing device (110) can maintain the reference temperature (T0) of the support (210) for a predetermined period of time that is preset or determined based on semiconductor process recipe information.
[0069] In step S404, the substrate processing device (110) according to the embodiment of the present disclosure may switch to a second heating mode and turn on each of the plurality of lasers (230_1, 230_2, 230_3, 230_4, see FIG. 2). Laser light emitted from each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) may be absorbed by the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4). The light energy absorbed by the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4) is conducted to the support member (210), and the heat energy conducted to the support member (210) can be transferred to the substrate (SUB) on the support member (210).
[0070] In step S404, the output amount and output direction of each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) may be determined based on at least a portion of the output wavelength range information of each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) and the light absorption rate information of each of the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) included in the semiconductor process recipe information. For convenience of explanation, in step S404, the output amount of each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) will be referred to as the first output. In an embodiment, power supply to the heating coil (211) may be maintained even while the substrate processing device (110) operates in the second heating mode.
[0071] In step S405, the substrate processing device (110) according to the embodiment of the present disclosure can check whether the temperature (T) of the support chuck (210) is less than the target temperature (T1). If it is confirmed that the temperature (T) of the support chuck (210) is less than the target temperature (T1), the procedure can return to step S404. On the other hand, if it is confirmed that the temperature (T) of the support chuck (210) has reached the target temperature (T1), the procedure can proceed to step S406.
[0072] In step S406, the substrate processing device (110) according to the embodiment of the present disclosure can maintain the temperature (T) of the support member (210) at the target temperature (T1). Specifically, the substrate processing device (110) can maintain power supply to the heating coil (211) and laser light irradiation by a plurality of lasers (230_1, 230_2, 230_3, 230_4) to maintain the target temperature (T1) of the support member (210) under the control of the electronic device (120). However, in the above-described step S404, in order to achieve a rapid temperature increase of the support chuck (210), each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) irradiates laser light corresponding to the first output, but in order to maintain the temperature (T) of the support chuck (210) at the target temperature (T1), each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) may irradiate laser light corresponding to the second output that is lower than the first output. In an embodiment, the substrate processing device (110) may maintain the target temperature (T1) of the support chuck (210) for a predetermined time that is preset or determined based on semiconductor process recipe information.
[0073] At step S407, the substrate processing device (110) according to the embodiment of the present disclosure can confirm that the process for the substrate (SUB) is completed and turn off the plurality of lasers (230_1, 230_2, 230_3, 230_4). The substrate (SUB) whose process is confirmed to be completed can be transferred to a chamber for performing the next process. As the plurality of lasers (230_1, 230_2, 230_3, 230_4) are turned off, the temperature (T) of the support (210) corresponding to the target temperature (T1) can be lowered. Meanwhile, as the plurality of lasers (230_1, 230_2, 230_3, 230_4) are turned off, the operation mode of the substrate processing device (110) may be switched from the second heating mode to the first heating mode, and as the substrate processing device (110) operates in the first heating mode, power supply to the heating coil (211) may be maintained. In some embodiments, the amount of power supplied to the heating coil (211) in step S407 may be the same as the amount of power supplied to the heating coil (211) in step S403.
[0074] In step S408, the electronic device (120) according to the embodiment of the present disclosure can check whether the operation of the substrate processing device (110) has ended. If it is determined that the substrate (SUB) to be processed by the substrate processing device (110) remains, the electronic device (120) can check not to end the operation of the substrate processing device (110), and in this case, the procedure can return to step S403. By returning to step S403, the temperature of the support (210) can be maintained at the reference temperature (T0), which is a preheating temperature required before performing a process on the substrate (SUB), thereby facilitating fast and efficient processing of the substrate (SUB) additionally supplied to the substrate processing device (110). Meanwhile, if it is determined that there is no substrate (SUB) remaining to be processed by the substrate processing device (110), the electronic device (120) can be determined to terminate the operation of the substrate processing device (110), and in this case, the procedure can proceed to step S409.
[0075] At step S409, the substrate processing device (110) according to the embodiment of the present disclosure may stop supplying power to the heating coil (211). As the power supply to the heating coil (211) is stopped, the temperature (T) of the support member (210) may drop below the reference temperature (T0).
[0076] FIG. 5a is a drawing for explaining the operating principle of a substrate processing device (500a) operating in a first heating mode according to one embodiment of the present disclosure.
[0077] The substrate processing device (500a) illustrated in FIG. 5a may correspond to the substrate processing device (110, see FIG. 1) of FIG. 1 described above. In an embodiment, the first heating mode may mean an operation mode for increasing the temperature to a reference temperature and maintaining the reference temperature. The reference temperature is any temperature that is higher than room temperature and lower than a target temperature for performing a process on the substrate (SUB), and may be a temperature preset in the substrate processing system (10, see FIG. 1) or a temperature derived based on semiconductor process recipe information stored in the memory of the electronic device (120, see FIG. 1). In some embodiments, the reference temperature may mean a preheating temperature that the support member (510) must maintain in order to perform a process on the substrate (SUB).
[0078] In an embodiment, when the substrate processing device (500a) operates in the first heating mode, power may be supplied to the heating coil (511) included in the support chuck (510) under the control of the electronic device (120). The amount of power supplied to the heating coil (511) may be determined based on semiconductor process recipe information stored in the electronic device (120). For example, the power provided to the heating coil (511) may be determined based on at least a portion of the thermal conductivity information of the support chuck (510) and the heat generation capacity information of the heating coil (511) included in the semiconductor process recipe information. The heating coil (511) may generate heat based on the supplied power, and the heat energy generated by the heating coil (511) may be conducted to the support chuck (510). Power may be supplied to the heating coil (511) under the control of the electronic device (120) so that the temperature of the support chuck (510) reaches a reference temperature.
[0079] In an embodiment, when the temperature of the support chuck (510) reaches a reference temperature, power may be supplied to the heating coil (511) under the control of the electronic device (120) so that the temperature of the support chuck (510) is maintained at the reference temperature. In some embodiments, while the temperature of the support chuck (510) is maintained at the reference temperature, the substrate (SUB) may be placed on the support chuck (510), and thermal energy for the support chuck (510) may be conducted to the substrate (SUB), and the temperature of the substrate (SUB) may also rise. In an embodiment, the substrate (SUB) may be provided from a chamber for performing a process preceding a process performed in the substrate processing apparatus (500a), and the substrate processing apparatus (500a) may align the substrate (SUB) provided on the support chuck (510) in an arrangement that is easy to perform the process performed within the substrate processing apparatus (500a). In an embodiment, the substrate processing device (500a) may operate in a second heating mode after maintaining a reference temperature for a predetermined period of time that is preset or determined based on semiconductor process recipe information, and specific operations related to the second heating mode operation will be described later with reference to FIG. 5b.
[0080] FIG. 5b is a drawing for explaining the operating principle of a substrate processing device (500b) operating in a second heating mode according to one embodiment of the present disclosure.
[0081] The substrate processing device (500b) illustrated in FIG. 5b may correspond to the substrate processing device (110, see FIG. 1) of FIG. 1 described above. In an embodiment, the second heating mode may mean an operation mode for increasing the temperature to a target temperature and maintaining a reference temperature, and the target temperature is a temperature for performing a process on a substrate (SUB, see FIG. 2), and may be a temperature preset in the substrate processing system (10, see FIG. 1) or a temperature derived based on semiconductor process recipe information stored in the memory of an electronic device (120, see FIG. 1).
[0082] In an embodiment, when the substrate processing device (500b) operates in the second heating mode, each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) may be turned on under the control of the electronic device (120). Each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) may irradiate laser light to the plurality of light absorbing portions (540_1, 540_2, 540_3, 540_4) corresponding to at least one of an output wavelength and an output angle determined based on semiconductor process recipe information stored in the electronic device (120). For example, the output wavelength and output angle of each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) may be determined based on at least a portion of the output wavelength range information of the laser and the light absorption rate information of the light absorbing portion included in the semiconductor process recipe information. The laser light irradiated from each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) may be absorbed by the plurality of light absorbing portions (540_1, 540_2, 540_3, 540_4), and the light energy absorbed by the plurality of light absorbing portions (540_1, 540_2, 540_3, 540_4) may be conducted to the support chuck (510), and the energy conducted to the support chuck (510) may be conducted to the substrate (SUB) on the support chuck (510).
[0083] In FIG. 5b, the laser light irradiated from the first laser (530_1) is absorbed by the first light absorbing portion (540_1), the laser light irradiated from the second laser (530_2) is absorbed by the second light absorbing portion (540_2), the laser light irradiated from the third laser (530_3) is absorbed by the third light absorbing portion (540_3), and the laser light irradiated from the fourth laser (530_4) is absorbed by the fourth light absorbing portion (540_4). However, this is merely an example according to the present disclosure, and does not limit the operation of the substrate processing device (500b) according to the present disclosure. In some embodiments, the laser light emitted from the first laser (530_1) may be absorbed by the first light absorbing portion (540_1) and the second light absorbing portion (540_2), and the laser light emitted from the second laser (530_2) may also be absorbed by the first light absorbing portion (540_1) and the second light absorbing portion (540_2). That is, each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) can irradiate laser light to at least one light absorbing portion corresponding to each of the plurality of lasers (530_1, 530_2, 530_3, 530_4), and the at least one light absorbing portion corresponding to each of the plurality of lasers (530_1, 530_2, 530_3, 530_4) can be preset or determined based on semiconductor process recipe information stored in the electronic device (120).
[0084] In an embodiment, laser light may be irradiated from a plurality of lasers (530_1, 530_2, 530_3, 530_4) to a plurality of light absorbing portions (540_1, 540_2, 540_3, 540_4) so that the temperature of the support chuck (510) reaches a target temperature under the control of the electronic device (120). In addition, when the temperature of the support chuck (510) reaches the target temperature, laser light may be irradiated so that the temperature of the support chuck (510) maintains the target temperature under the control of the electronic device (120). In an embodiment, the substrate processing device (500b) may maintain the target temperature for a predetermined time that is preset or determined based on semiconductor process recipe information. Meanwhile, even when the substrate processing device (500b) operates in the second heating mode, power supply to the heating coil (511) can be maintained, and in this case, the support member (510) can reach the target temperature and maintain the target temperature by utilizing both the heat energy generated by the heating coil (511) and the light energy absorbed from the plurality of light absorbing parts (540_1, 540_2, 540_3, 540_4).
[0085] FIG. 6 is a drawing showing a temperature change according to a heating process operation of a substrate processing device (110, see FIG. 1) according to one embodiment of the present disclosure.
[0086] More specifically, FIG. 6 illustrates the temperature change pattern of the support chuck (210) during the process in which the substrate processing device (110) is turned on, operates in the first heating mode, switches to the second heating mode when the temperature of the support chuck (210, see FIG. 2) reaches the reference temperature (T0), switches back to the first heating mode when the temperature of the support chuck (210) reaches the target temperature (T1), and ends the process for the substrate (SUB, see FIG. 2) by turning the device (110) off.
[0087] When the operation by the substrate processing device (110) starts, the substrate processing device (110) operates in the first heating mode, and power can be supplied to the heating coil (211, see FIG. 2) so that the temperature of the support chuck (210) reaches the reference temperature (T0). The heating coil (211) can generate heat based on the supplied power, and the temperature of the support chuck (210) can reach the reference temperature (T0) based on the thermal energy by the heating coil (211), as shown in the period 0 to t1 of FIG. 6. In addition, the temperature of the support chuck (210) can be maintained at the reference temperature (T0) based on the thermal energy by the heating coil (211), as shown in the period t1 to t2 of FIG. 6, and within the period t1 to t2, the substrate (SUB) can be placed on the support chuck (210).
[0088] When the temperature of the support chuck (210) reaches the reference temperature (T0) and the substrate (SUB) is placed on the support chuck (210), the thermal energy of the support chuck (210) can be transferred to the substrate (SUB), and the temperature of the substrate (SUB) can reach the reference temperature (T0) based on the thermal balance principle. When the temperature of the substrate (SUB) reaches the reference temperature (TO), the substrate processing device (110) can operate in the second heating mode to turn on a plurality of lasers (230_1, 230_2, 230_3, 230_4, see FIG. 2) so that the temperature of the support chuck (210) reaches the target temperature (T1). Laser light irradiated from a plurality of lasers (230_1, 230_2, 230_3, 230_4) can be absorbed through a plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4, see FIG. 2) arranged on one surface of the support member (210), and the temperature of the support member (210) can reach the target temperature (T1) based on the light energy absorbed through the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) as in the t2 to t3 section of FIG. 6. In addition, as shown in the t3 to t4 section of FIG. 6, the temperature of the support (210) can be maintained at the target temperature (T1) for performing a process on the substrate (SUB) based on the light energy absorbed from the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4).
[0089] Alternatively, in some embodiments, the substrate processing device (110) may operate in the second heating mode even before the temperature of the substrate (SUB) reaches the reference temperature (TO), in which case the substrate processing device (110) may turn on the plurality of lasers (230_1, 230_2, 230_3, 230_4) so that the temperature of the support member (210) reaches the target temperature (T1). Laser light irradiated from a plurality of lasers (230_1, 230_2, 230_3, 230_4) can be absorbed through a plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4, see FIG. 2) arranged on one surface of the support member (210), and the temperature of the support member (210) can reach the target temperature (T1) based on the light energy absorbed through the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) as in the t2 to t3 section of FIG. 6. When the temperature of the support member (210) reaches the target temperature (T1), the temperature of the support member (210) can be maintained at the target temperature (T1) for performing a process on the substrate (SUB) based on the light energy absorbed from the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) as shown in the t3 to t4 section of FIG. 6.
[0090] When the process for the substrate (SUB) is completed, the substrate processing device (210) can turn off the plurality of lasers (230_1, 230_2, 230_3, 230_4) and perform a mode change to the first heating mode, as shown in the section t4 to t5 of FIG. 6. As the plurality of lasers (230_1, 230_2, 230_3, 230_4) are turned off, the temperature of the support beam (210) can decrease and reach the reference temperature (TO).
[0091] Meanwhile, the substrate processing device (210) operating in the first heating mode, as shown in the t5 to t6 section of FIG. 6, can maintain the temperature of the support chuck (210) at the reference temperature (T0) based on the thermal energy generated by the heating coil (211). The support chuck (210) maintaining the reference temperature (T0) can facilitate more quickly performing a process for a subsequently provided substrate (SUB). Meanwhile, when the operation of the substrate processing device (210) is stopped, the power supply to the heating coil (211) may be cut off, and thus, the temperature of the support chuck (210) may decrease, as shown in the section after t6 of FIG. 6.
[0092] FIG. 7 is a flowchart for explaining an operation method of a substrate processing device (110, see FIG. 1) according to another embodiment of the present disclosure.
[0093] In the flowchart illustrated in FIG. 7, steps S701 to S703 may be operations included in a first heating mode of the substrate processing device (110), steps S704 to S706 may be operations included in a second heating mode of the substrate processing device (110), and steps S707 to S709 may be operations included in a third heating mode of the substrate processing device (110). The first heating mode may mean an operation mode for increasing the temperature of the support chuck (210, see FIG. 2) to a reference temperature and maintaining the reference temperature, the second heating mode may mean an operation mode for increasing the temperature of the support chuck (210) to a first target temperature and maintaining the target temperature, and the third heating mode may mean an operation mode for increasing the temperature of the support chuck (210) to a second target temperature and maintaining the target temperature.
[0094] In an embodiment, the reference temperature may be set to be higher than room temperature and lower than the first target temperature, and in some embodiments, the reference temperature may mean a preheating temperature required for the support (210) when performing a process on the substrate (SUB, see FIG. 2). In an embodiment, the reference temperature may be set based on specification information of components constituting the substrate processing device (110). Meanwhile, the first target temperature means a temperature required to perform a first process on the substrate (SUB), and the second target temperature means a temperature required to perform a second process on the substrate (SUB), and may be set differently depending on the type of process to be performed through the substrate processing device (110). As a specific example, the first process may be a soaking process and the second process may be a wetting process, but the types of the first process and the second process according to the embodiments of the present disclosure are not limited, and the second process may be any process procedure in which the process is performed at a higher temperature than the first process.
[0095] In step S701, the substrate processing device (110) according to an embodiment of the present disclosure can supply power to the heating coil (211, see FIG. 2) included in the support chuck (210) under the control of the electronic device (120, see FIG. 1). The amount of power supplied to the heating coil (211) in step S701 may be preset or determined based on semiconductor process recipe information stored in the electronic device (120). For example, the amount of power provided to the heating coil (211) may be determined based on at least a portion of the thermal conductivity information of the support chuck (210) and the heat generation capacity information of the heating coil (211) included in the semiconductor process recipe information, and may be determined by considering the temperature increase efficiency of the support chuck (210) relative to the amount of power supplied. The heating coil (211) may generate heat based on the supplied power, and the heat energy generated by the heat generation of the heating coil (211) may be conducted to the support chuck (210).
[0096] In step S702, the substrate processing device (110) according to the embodiment of the present disclosure can check whether the temperature (T) of the support chuck (210) is less than the reference temperature (T0). If it is confirmed that the temperature (T) of the support chuck (210) is less than the reference temperature (T0), the procedure can return to step S701. On the other hand, if it is confirmed that the temperature (T) of the support chuck (210) has reached the reference temperature (T0), the procedure can proceed to step S703.
[0097] In step S703, the substrate processing device (110) according to the embodiment of the present disclosure can maintain the temperature (T) of the support chuck (210) at the reference temperature (T0). Specifically, the substrate processing device (110) can supply power to the heating coil (211) to maintain the reference temperature (T0) of the support chuck (210) under the control of the electronic device (120), and the amount of power supplied to the heating coil (211) to maintain the reference temperature (T0) of the support chuck (210) can be less than or equal to the amount of power supplied to the heating coil (211) in step S401. While the support chuck (210) maintains the reference temperature (T0), a substrate (SUB) can be placed on one surface of the support chuck (210). Thermal energy of the support chuck (210) can be transferred to the substrate (SUB). In an embodiment, the substrate processing device (110) can maintain the reference temperature (T0) of the support (210) for a predetermined period of time that is preset or determined based on semiconductor process recipe information.
[0098] In step S704, the substrate processing device (110) according to the embodiment of the present disclosure may switch to the second heating mode and turn on a first laser set composed of some of a plurality of lasers (230_1, 230_2, 230_3, 230_4, see FIG. 2). For convenience of explanation, it is assumed that the first laser set includes a first laser (230_1) and a fourth laser (230_4). Laser light irradiated from the first laser set may be absorbed by at least some of a plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4, see FIG. 2). The first light energy absorbed by at least some of the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4) is conducted to the support member (210), and the thermal energy conducted to the support member (210) can be transferred to the substrate (SUB) on the support member (210).
[0099] In step S704, the output amount and output direction of each of the first laser (230_1) and the fourth laser (230_4) may be determined based on at least a portion of the output wavelength range information of each of the first laser (230_1) and the fourth laser (230_4) and the light absorption rate information of each of the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4) included in the semiconductor process recipe information. For convenience of explanation, in step S704, the output amount of each of the first laser (230_1) and the fourth laser (230_4) will be referred to as the first output. In an embodiment, power supply to the heating coil (211) may be maintained even while the substrate processing device (110) operates in the second heating mode.
[0100] In step S705, the substrate processing device (110) according to the embodiment of the present disclosure can check whether the temperature (T) of the support chuck (210) is less than the first target temperature (T1). If it is confirmed that the temperature (T) of the support chuck (210) is less than the first target temperature (T1), the procedure can return to step S704. On the other hand, if it is confirmed that the temperature (T) of the support chuck (210) has reached the first target temperature (T1), the procedure can proceed to step S706.
[0101] In step S706, the substrate processing device (110) according to the embodiment of the present disclosure can maintain the temperature (T) of the support chuck (210) at the first target temperature (T1). Specifically, the substrate processing device (110) can maintain the power supply to the heating coil (211) and the laser light irradiation by the first laser set to maintain the first target temperature (T1) of the support chuck (210) under the control of the electronic device (120). However, in step S704 described above, in order to promote a rapid temperature increase of the support chuck (210), each of the first laser (230_1) and the fourth laser (230_4) irradiates laser light corresponding to the first output, but in maintaining the temperature (T) of the support chuck (210) at the first target temperature (T1), each of the first laser (230_1) and the fourth laser (230_4) can irradiate laser light corresponding to the second output that is lower than the first output. In an embodiment, the substrate processing device (110) can maintain the first target temperature (T1) of the support (210) for a predetermined period of time that is preset or determined based on semiconductor process recipe information.
[0102] At step S707, the substrate processing device (110) according to the embodiment of the present disclosure may switch to a third heating mode and additionally turn on a second laser set including at least some of the remaining lasers excluding the first laser set among the plurality of lasers (230_1, 230_2, 230_3, 230_4, see FIG. 2). For convenience of explanation, it is assumed that the second laser set includes the second laser (230_2) and the third laser (230_3). Laser light irradiated from the first laser set and the second laser set may be absorbed by at least some of the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4, see FIG. 2). The second light energy absorbed by at least some of the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4) is conducted to the support member (210), and the thermal energy conducted to the support member (210) can be transferred to the substrate (SUB) on the support member (210).
[0103] In step S707, the output amount and output direction of each of the plurality of lasers (730_1, 730_2, 730_3, 730_4) may be determined based on at least a portion of the output wavelength range information of each of the plurality of lasers (730_1, 730_2, 730_3, 730_4) and the light absorption rate information of each of the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) included in the semiconductor process recipe information. For convenience of explanation, in step S707, the output amount of each of the plurality of lasers (730_1, 730_2, 730_3, 730_4) will be referred to as the third output. In an embodiment, power supply to the heating coil (211) may be maintained even while the substrate processing device (110) operates in the third heating mode.
[0104] At step S708, the substrate processing device (110) according to the embodiment of the present disclosure can check whether the temperature (T) of the support chuck (210) is less than the second target temperature (T2). If it is confirmed that the temperature (T) of the support chuck (210) is less than the second target temperature (T2), the procedure can return to step S707. On the other hand, if it is confirmed that the temperature (T) of the support chuck (210) has reached the second target temperature (T2), the procedure can proceed to step S709.
[0105] At step S709, the substrate processing device (110) according to the embodiment of the present disclosure can maintain the temperature (T) of the support member (210) at the second target temperature (T2). Specifically, the substrate processing device (110) can maintain power supply to the heating coil (211) and laser light irradiation by the first laser set and the second laser set to maintain the second target temperature (T2) of the support member (210) under the control of the electronic device (120). However, in the above-described step S707, in order to achieve a rapid temperature increase of the support chuck (210), each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) irradiates laser light corresponding to the third output, but in order to maintain the temperature (T) of the support chuck (210) at the second target temperature (T2), each of the plurality of lasers (230_1, 230_2, 230_3, 230_4) may irradiate laser light corresponding to the fourth output that is lower than the third output. In an embodiment, the substrate processing device (110) may maintain the second target temperature (T2) of the support chuck (210) for a predetermined time that is preset or determined based on semiconductor process recipe information.
[0106] At step S710, the substrate processing device (110) according to the embodiment of the present disclosure can confirm that the first process and the second process for the substrate (SUB) are completed, and can turn off the plurality of lasers (230_1, 230_2, 230_3, 230_4). The substrate (SUB), for which the process is confirmed to be completed, can be transferred to a chamber for performing the next process. As the plurality of lasers (230_1, 230_2, 230_3, 230_4) are turned off, the temperature (T) of the support (210) corresponding to the second target temperature (T2) can be lowered. Meanwhile, as the plurality of lasers (230_1, 230_2, 230_3, 230_4) are turned off, the operation mode of the substrate processing device (110) may be switched from the third heating mode to the first heating mode, and as the substrate processing device (110) operates in the first heating mode, power supply to the heating coil (211) may be maintained. In some embodiments, the amount of power supplied to the heating coil (211) in step S710 may be the same as the amount of power supplied to the heating coil (211) in step S703.
[0107] In step S711, the electronic device (120) according to the embodiment of the present disclosure can check whether the operation of the substrate processing device (110) has ended. If it is determined that the substrate (SUB) to be processed by the substrate processing device (110) remains, the electronic device (120) can check not to end the operation of the substrate processing device (110), and in this case, the procedure can return to step S703. By returning to step S703, the temperature of the support (210) can be maintained at the reference temperature (T0), which is a preheating temperature required before performing a process on the substrate (SUB), thereby facilitating fast and efficient processing of the substrate (SUB) additionally supplied to the substrate processing device (110). Meanwhile, if it is determined that there is no substrate (SUB) remaining to be processed by the substrate processing device (110), the electronic device (120) can be determined to terminate the operation of the substrate processing device (110), and in this case, the procedure can proceed to step S712.
[0108] At step S712, the substrate processing device (110) according to the embodiment of the present disclosure may stop supplying power to the heating coil (211). As the power supply to the heating coil (211) is stopped, the temperature (T) of the support member (210) may drop below the reference temperature (T0).
[0109] FIG. 8a is a drawing for explaining the operating principle of a substrate processing device (800a) operating in a first heating mode according to another embodiment of the present disclosure.
[0110] The substrate processing device (800a) illustrated in FIG. 8A may correspond to the substrate processing device (110, see FIG. 1) of FIG. 1 described above. The substrate processing device (800a) operating in the first heating mode illustrated in FIG. 8A can generate heat based on the power supplied to the heating coil (811), similar to the substrate processing device (500a) operating in the first heating mode illustrated in FIG. 5A described above, and the heat energy generated by the heating coil (811) can be conducted to the support member (810). The support member (810) can reach a reference temperature based on the heat energy generated by the heating coil (811) and maintain the reference temperature. Hereinafter, any overlapping content with the first heating mode operation described with reference to FIG. 5A will be omitted.
[0111] FIG. 8b is a drawing for explaining the operating principle of a substrate processing device operating in a second heating mode according to another embodiment of the present disclosure.
[0112] The substrate processing device (800b) illustrated in FIG. 8b may correspond to the substrate processing device (110, see FIG. 1) of FIG. 1 described above. In the embodiment illustrated in FIG. 8b, the second heating mode may mean an operation mode for increasing the temperature to a first target temperature and maintaining the reference temperature, and the first target temperature is a temperature for performing a first process on a substrate (SUB, see FIG. 2), and may be a temperature preset in the substrate processing system (10, see FIG. 1) or a temperature derived based on semiconductor process recipe information stored in the memory of an electronic device (120, see FIG. 1).
[0113] In an embodiment, when the substrate processing device (800b) operates in the second heating mode, a first laser set including some of the plurality of lasers (830_1, 830_2, 830_3, 830_4) may be turned on under the control of the electronic device (120). In the embodiment illustrated in FIG. 8b, the first laser set may be composed of a first laser (830_1) and a fourth laser (830_4). Each of the first laser (830_1) and the fourth laser (830_4) may irradiate laser light to the light absorbing portion corresponding to each of the first laser (830_1) and the fourth laser (830_4) in response to at least one of an output wavelength and an output angle determined based on semiconductor process recipe information stored in the electronic device (120). The output wavelength and output angle of each of the first laser (830_1) and the fourth laser (830_4) may be determined based on at least a portion of the output wavelength range information of the laser and the light absorption rate information of the light absorption portion included in the semiconductor process recipe information.
[0114] In the embodiment illustrated in FIG. 8B, the first laser (830_1) can irradiate laser light to the first light absorbing portion (840_1), and the fourth laser (830_4) can irradiate laser light to the fourth light absorbing portion (840_4). The light energy absorbed from the first light absorbing portion (840_1) and the fourth light absorbing portion (840_4) can be conducted to the support portion (810), and the energy conducted to the support portion (810) can be conducted to the substrate (SUB) on the support portion (810).
[0115] In FIG. 8b, the laser light irradiated from the first laser (830_1) is illustrated as being absorbed by the first light absorbing portion (840_1), and the laser light irradiated from the fourth laser (830_4) is illustrated as being absorbed by the fourth light absorbing portion (840_4). However, this is only one embodiment according to the present disclosure, and does not limit the operation of the substrate processing device (800b) according to the present disclosure. In some embodiments, the laser light irradiated from the first laser (830_1) may be absorbed by the first light absorbing portion (840_1) and the second light absorbing portion (840_2), and the laser light irradiated from the fourth laser (830_4) may be absorbed by the third light absorbing portion (840_3) and the fourth light absorbing portion (840_4). That is, each laser included in the first laser set can irradiate laser light to at least one light absorbing portion corresponding to each laser, and the at least one light absorbing portion corresponding to each laser can be preset or determined based on semiconductor process recipe information stored in the electronic device (120).
[0116] In the embodiment illustrated in FIG. 8b, laser light may be irradiated from the first laser (830_1) and the fourth laser (830_4) to the first light absorbing portion (840_1) and the fourth light absorbing portion (840_4) so that the temperature of the support chuck (810) reaches the first target temperature under the control of the electronic device (120). In addition, when the temperature of the support chuck (810) reaches the first target temperature, laser light may be irradiated so that the temperature of the support chuck (810) maintains the target temperature under the control of the electronic device (120). In the embodiment, the substrate processing device (800b) may maintain the target temperature for a predetermined time that is preset or determined based on semiconductor process recipe information. Meanwhile, even when the substrate processing device (800b) operates in the second heating mode, power supply to the heating coil (811) can be maintained, and in this case, the support member (810) can reach the first target temperature and maintain the first target temperature by using both the heat energy generated by the heating coil (811) and the light energy absorbed from the first light absorbing portion (840_1) and the fourth light absorbing portion (840_4).
[0117] FIG. 8c is a drawing for explaining the operating principle of a substrate processing device (800c) operating in a third heating mode according to another embodiment of the present disclosure.
[0118] The substrate processing device (800c) illustrated in FIG. 8c may correspond to the substrate processing device (110, see FIG. 1) of FIG. 1 described above. In the embodiment illustrated in FIG. 8c, the third heating mode may refer to an operation mode for increasing the temperature to a second target temperature and maintaining the reference temperature, and the second target temperature is a temperature for performing a second process on a substrate (SUB, see FIG. 2), which may be a temperature preset in the substrate processing system (10, see FIG. 1) or a temperature derived based on semiconductor process recipe information stored in the memory of an electronic device (120, see FIG. 1). In the embodiment, the first target temperature corresponding to the first heating mode of the substrate processing device (110) may be lower than the second target temperature corresponding to the third heating mode.
[0119] In an embodiment, when the substrate processing device (800c) operates in the third heating mode, a second laser set may be additionally turned on in addition to the first laser set in FIG. 8b described above by the control of the electronic device (120). The second laser set may include at least some of the remaining lasers (830_1, 830_2, 830_3, 830_4) excluding the first laser set. In the embodiment illustrated in FIG. 8c, it is assumed that the first laser set is composed of the first laser (830_1) and the fourth laser (830_4), and the second laser set is composed of the second laser (830_2) and the third laser (830_3). In the embodiment illustrated in FIG. 8c, when the substrate processing device (800c) operates in the third heating mode, all of the plurality of lasers (830_1, 830_2, 830_3, 830_4) may be turned on, and each of the plurality of lasers (830_1, 830_2, 830_3, 830_4) may irradiate laser light to the light absorbing portion corresponding to each of the plurality of lasers (830_1, 830_2, 830_3, 830_4) in response to at least one of the output wavelength and the output angle determined based on the semiconductor process recipe information stored in the electronic device (120). The output wavelength and the output angle of each of the plurality of lasers (830_1, 830_2, 830_3, 830_4) may be determined based on at least a part of the output wavelength range information of the laser and the light absorption rate information of the light absorbing portion included in the semiconductor process recipe information.
[0120] In the embodiment illustrated in FIG. 8C, the first laser (830_1) can irradiate laser light to the first light absorbing portion (840_1), the second laser (830_2) can irradiate laser light to the second light absorbing portion (840_2), the third laser (830_3) can irradiate laser light to the third light absorbing portion (840_3), and the fourth laser (840_4) can irradiate laser light to the fourth light absorbing portion (840_4). The light energy absorbed from the plurality of light absorbing portions (840_1, 840_2, 840_3, 840_4) can be conducted to the support portion (810), and the energy conducted to the support portion (810) can be conducted to the substrate (SUB) on the support portion (810).
[0121] In FIG. 8c, the laser light irradiated from the first laser (830_1) is absorbed by the first light absorbing portion (840_1), the laser light irradiated from the second laser (830_2) is absorbed by the second light absorbing portion (840_2), the laser light irradiated from the third laser (830_3) is absorbed by the third light absorbing portion (840_3), and the laser light irradiated from the fourth laser (830_4) is absorbed by the fourth light absorbing portion (840_4). However, this is only one embodiment according to the present disclosure, and does not limit the operation of the substrate processing device (800c) according to the present disclosure. In an embodiment, each of the plurality of lasers (830_1, 830_2, 830_3, 830_4) can irradiate laser light to at least one light absorbing portion corresponding to each of the plurality of lasers (830_1, 830_2, 830_3, 830_4), and the at least one light absorbing portion corresponding to each of the plurality of lasers (830_1, 830_2, 830_3, 830_4) can be preset or determined based on semiconductor process recipe information stored in the electronic device (120).
[0122] In the embodiment illustrated in FIG. 8c, laser light may be irradiated from a plurality of lasers (830_1, 830_2, 830_3, 830_4) to a plurality of light absorbing portions (840_1, 840_2, 840_3, 840_4) so that the temperature of the support chuck (810) reaches a second target temperature under the control of the electronic device (120). In addition, when the temperature of the support chuck (810) reaches the second target temperature, laser light may be irradiated so that the temperature of the support chuck (810) maintains the second target temperature under the control of the electronic device (120). In the embodiment, the substrate processing device (800c) may maintain the second target temperature for a predetermined time that is preset or determined based on semiconductor process recipe information. Meanwhile, even when the substrate processing device (800c) operates in the third heating mode, power supply to the heating coil (811) can be maintained, and in this case, the support member (810) can reach the second target temperature and maintain the second target temperature by using both the heat energy generated by the heating coil (811) and the light energy absorbed from the plurality of light absorbing parts (840_1, 840_2, 840_3, 840_4).
[0123] FIG. 9 is a drawing showing a temperature change according to a heating process operation of a substrate processing device (110, see FIG. 1) according to another embodiment of the present disclosure.
[0124] More specifically, FIG. 9 illustrates the temperature change pattern of the support chuck (210) during the process in which the substrate processing device (110) is turned on, operates in the first heating mode, switches to the second heating mode when the temperature of the support chuck (210, see FIG. 2) reaches the reference temperature (T0), switches to the third heating mode when the temperature of the support chuck (210) reaches the first target temperature (T1), switches to the first heating mode again when the temperature of the support chuck (210) reaches the second target temperature (T2) to complete the target process, and ends the process for the substrate (SUB, see FIG. 2) thereby turning off the substrate processing device (110).
[0125] When the operation by the substrate processing device (110) starts, the substrate processing device (110) operates in the first heating mode, and power can be supplied to the heating coil (211, see FIG. 2) so that the temperature of the support chuck (210) reaches the reference temperature (T0). The heating coil (211) can generate heat based on the supplied power, and the temperature of the support chuck (210) can reach the reference temperature (T0) based on the thermal energy by the heating coil (211), as shown in the period 0 to t1 of FIG. 6. In addition, the temperature of the support chuck (210) can be maintained at the reference temperature (T0) based on the thermal energy by the heating coil (211), as shown in the period t1 to t2 of FIG. 6, and within the period t1 to t2, the substrate (SUB) can be placed on the support chuck (210).
[0126] When the temperature of the support chuck (210) reaches the reference temperature (T0) and the substrate (SUB) is placed on the support chuck (210), the thermal energy of the support chuck (210) can be transferred to the substrate (SUB), and the temperature of the substrate (SUB) can reach the reference temperature (T0) based on the thermal balance principle. When the temperature of the substrate (SUB) reaches the reference temperature (TO), the substrate processing device (110) can operate in a second heating mode to turn on a first laser set composed of at least some of the plurality of lasers (230_1, 230_2, 230_3, 230_4, see FIG. 2) so that the temperature of the support chuck (210) reaches the first target temperature (T1). In explaining FIG. 9, it is assumed that the first laser set is composed of the first laser (230_1) and the fourth laser (230_4), and the first target temperature (T1) can correspond to the temperature for performing the first process on the support (210).
[0127] The laser light irradiated from the first laser (230_1) and the fourth laser (230_4) can be absorbed through the light absorbing portions corresponding to the first laser (230_1) and the fourth laser (230_4) among the plurality of light absorbing portions (240_1, 240_2, 240_3, 240_4, see FIG. 2) arranged on one surface of the support (210), and in describing FIG. 9, it is assumed that the laser light irradiated from the first laser (230_1) is absorbed through the first light absorbing portion (230_1), and the laser light irradiated from the fourth laser (240_4) is absorbed through the fourth light absorbing portion (240_4). As shown in the t2 to t3 sections of FIG. 9, the temperature of the support member (210) can reach the first target temperature (T1) based on the light energy absorbed through the first light absorbing member (240_1) and the fourth light absorbing member (240_4). In addition, as shown in the t3 to t4 sections of FIG. 9, the temperature of the support member (210) can maintain the first target temperature (T1) for performing a process on the substrate (SUB) based on the light energy absorbed from the first light absorbing member (240_1) and the fourth light absorbing member (240_4).
[0128] Alternatively, in some embodiments, the substrate processing device (110) may operate in the second heating mode even before the temperature of the substrate (SUB) reaches the reference temperature (TO), in which case the substrate processing device (110) may turn on the first laser set including the first laser (230_1) and the fourth laser (230_4) so that the temperature of the support (210) reaches the first target temperature (T1). The laser light irradiated from the first laser (230_1) and the fourth laser (230_4) can be absorbed through the first light absorbing portion (240_1) and the fourth light absorbing portion (240_4) arranged on one surface of the support chuck (210), and the temperature of the support chuck (210) can reach the first target temperature (T1) based on the light energy absorbed through the first light absorbing portion (240_1) and the fourth light absorbing portion (240_4), as shown in the t2 to t3 sections of FIG. 9. When the temperature of the support chuck (210) reaches the first target temperature (T1), the temperature of the support chuck (210) can be maintained at the first target temperature (T1) for performing a process on the substrate (SUB) based on the light energy absorbed from the first light absorbing portion (240_1) and the fourth light absorbing portion (240_4), as shown in the t3 to t4 sections of FIG. 9.
[0129] When the first process for the substrate (SUB) is completed, the substrate processing device (210) may operate in a third heating mode, as shown in the period t4 to t5 of FIG. 9, to turn on the second laser set composed of the second laser (230_2) and the third laser (230_3) so that the temperature of the support chuck (210) reaches the second target temperature (T2). The second target temperature (T2) may correspond to the temperature for performing the second process for the support chuck (210). In describing FIG. 9, it is assumed that the laser light irradiated from the second laser (230_2) is absorbed through the second light absorbing portion (230_2), and the laser light irradiated from the third laser (230_2) is absorbed through the third light absorbing portion (230_3).
[0130] The laser light irradiated from the first laser set and the second laser set can be absorbed through a plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4) arranged on one surface of the support chuck (210). As shown in the t4 to t5 sections of FIG. 9, the temperature of the support chuck (210) can reach the second target temperature (T2) based on the light energy absorbed through the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4). In addition, as shown in the t5 to t6 sections of FIG. 9, the temperature of the support chuck (210) can be maintained at the second target temperature (T2) for performing a process on the substrate (SUB) based on the light energy absorbed from the plurality of light absorbing parts (240_1, 240_2, 240_3, 240_4).
[0131] When the second process for the substrate (SUB) is completed, the substrate processing device (210) can perform a mode switch to the first heating mode, as shown in the section t6 to t7 of FIG. 9. As the operation mode of the substrate processing device (210) switches to the first heating mode, the first laser set, which is composed of the first laser (230_1) and the fourth laser (230_4), and the second laser set, which is composed of the second laser (230_2) and the third laser (230_3), can be turned off. As the first laser set and the second laser set are turned off, the temperature of the support member (210) can decrease and reach the reference temperature (T0).
[0132] Meanwhile, the substrate processing device (210) operating in the first heating mode, as shown in the t7 to t8 section of FIG. 9, can maintain the temperature of the support chuck (210) at the reference temperature (T0) based on the thermal energy generated by the heating coil (211). The support chuck (210) maintaining the reference temperature (T0) can facilitate more quickly performing a process for a subsequently provided substrate (SUB). Meanwhile, when the operation of the substrate processing device (210) is stopped, the power supply to the heating coil (211) may be cut off, and thus, the temperature of the support chuck (210) may decrease, as shown in the section after t8 of FIG. 9.
[0133] FIG. 10 is a block diagram illustrating the configuration of an electronic device (1000) according to an embodiment of the present disclosure.
