The foreign matter remover 240 can remove foreign matter from a surface of the first substrate before the first substrate and the second substrate are bonded to each other. In addition, the foreign matter remover 240 can remove foreign matter from a surface of the second substrate before the first substrate and the second substrate are bonded to each other.
[0081] The foreign matter remover 240 can remove foreign matter from a surface of the substrate WF using a brush. The foreign matter remover 240 can remove foreign matter from one portion of the substrate WF. For example, the foreign matter remover 240 can remove foreign matter from an edge region of the substrate WF. Generally, a large number of voids can occur in the edge region when the first substrate and the second substrate are bonded to each other. In the present embodiment, in consideration of this, the foreign matter remover 240 can remove foreign matter from the edge region of the substrate WF. However, embodiments of the present disclosure are not limited thereto, and the foreign matter remover 240 can remove foreign matter from the entire region of the substrate WF.
[0082] Referring to Figure 8 , the foreign matter remover 240 can include a power source 410, a motor 420, a shaft 430, and a brush 440. Figure 8 is a first example view illustrating a foreign matter remover of a substrate cleaning device according to some embodiments of the present disclosure.
[0083] The power source 410 can supply electric energy to the motor 420. The motor 420 can convert the electric energy into kinetic energy to rotate the shaft 430. The shaft 430 can rotate clockwise. Alternatively, the shaft 430 can rotate counterclockwise. The brush 440 can be connected to the shaft 430 and rotate in the same direction as a rotation direction of the shaft 430. The brush 440 can perform a spinning motion. The brush 440 can contact a surface of the substrate WF. The brush 440 can remove foreign matter from the surface of the substrate WF while rotating in contact with the surface of the substrate WF. The brush 440 can be made of a resin-based material to avoid damaging the surface of the substrate WF when removing foreign matter from the surface of the substrate WF. For example, the brush 440 can be made of a polyvinyl acetate (PVA) resin.
[0084] Referring to Figure 9, the brush 440 can rotate clockwise or counterclockwise about a rotation axis extending in a direction D3 perpendicular to the width direction D1 or D2 of the substrate WF. However, embodiments of the present disclosure are not limited thereto. Referring to Figure 10 , the brush 440 can also rotate clockwise or counterclockwise about a rotation axis extending in parallel with the width direction D1 or D2 of the substrate WF. The rotation axis of the brush 440 can be disposed below the main body 310 of the substrate support 210 that attracts the substrate WF, to shorten the brush movement. The rotation axis of the brush 440 can be configured as a brush shaft rotation structure. Figure 9 is a second example view for illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure. Figure 10 is a third example view for illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0085] The brush 440 can be operated simultaneously with the operation of the second liquid supplier 230. While the second liquid supplier 230 provides liquid to the lower surface of the substrate WF, the brush 440 can contact the surface of the substrate WF and rotate. The liquid provided by the second liquid supplier 230 can constitute a water film on the lower surface of the substrate WF. When the brush 440 removes foreign matter, the water film can minimize direct contact between the substrate WF and the brush 440. When the second liquid supplier 230 and the brush 440 are simultaneously operated with each other, damage to the lower surface of the substrate WF can be prevented.
[0086] The brush 440 can rotate and simultaneously move in a direction parallel to the width direction D1 or D2 of the substrate WF. The brush 440 can perform a wobbling motion. Referring to Figure 11 , the brush 440 can move in an outward direction while rotating. The brush 440 can move in the outward direction while contacting the surface of the substrate WF. The brush 440 can move linearly in the outward direction. Alternatively, the brush 440 can move curvilinearly in the outward direction. Referring to Figure 12 , the brush 440 can move in an inward direction while rotating. The brush 440 can move in the inward direction while contacting the surface of the substrate WF. The brush 440 can move linearly in the inward direction. Alternatively, the brush 440 can move curvilinearly in the inward direction. Rotating and simultaneously moving the brush 440 in the horizontal direction can allow uniform cleaning of the entire area of the lower surface of the substrate WF. Figure 11 is a fourth example view for illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure. Figure 12 is a fifth example view for illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0087] The foreign matter remover 240 can remove foreign matter while the substrate WF is rotating. In this case, the rotation direction of the brush 440 can be opposite to the rotation direction of the substrate WF. (Reference) Figure 13 When brush 440 uses the vertical direction D3 as its axis of rotation, as... Figure 9 As shown in the example, the substrate WF can rotate counterclockwise, and the brush 440 can rotate clockwise. Alternatively, according to an embodiment, the substrate WF can rotate clockwise, and the brush 440 can rotate counterclockwise. Furthermore, refer to... Figure 14 When brush 440 uses the horizontal direction D1 or D2 as its axis of rotation, such as Figure 10 As shown in the example, the substrate WF can rotate counterclockwise, and the brush 440 can rotate clockwise. Alternatively, according to the embodiment, the substrate WF can rotate clockwise, and the brush 440 can rotate counterclockwise. In one example, when the brush 440 has the vertical direction D3 as its axis of rotation, the rotation direction of the brush 440 can be the same as the rotation direction of the substrate WF. Figure 13 This is a sixth example diagram illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure. Figure 14 This is a seventh example diagram illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0088] The 440 brush can perform a flipping motion. (Reference) Figure 15 The upper surface of brush 440 is typically not facing the substrate WF. When cleaning of the substrate WF begins, the upper surface of brush 440 can be rotated during a flipping motion to face the substrate WF. When cleaning of the substrate WF is complete, the upper surface of brush 440 can be rotated again during a flipping motion so that the upper surface is not facing the substrate WF. The upper surface of brush 440 can then be returned to its original orientation. Figure 15 This is an eighth example diagram illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0089] The 440 brush can move up and down. (Reference) Figure 16 Typically, brush 440 can be positioned at a vertical height where it does not contact the lower surface of substrate WF. When cleaning of substrate WF begins, brush 440 can move upward to contact the lower surface of substrate WF. When cleaning of substrate WF is complete, brush 440 can descend so that it no longer contacts the lower surface of substrate WF. Brush 440 can return to its original position. Figure 16 This is a ninth example diagram illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0090] The foreign object remover 240 may also include a contact force measuring sensor 460. (Reference) Figure 17The contact force measurement sensor 460 can measure a contact force when the brush 440 contacts the lower surface of the substrate WF. The foreign matter remover 240 can control the vertical movement of the brush 440 based on the measured value of the contact force measurement sensor 460. The foreign matter remover 240 can adjust the contact force when the brush 440 contacts the lower surface of the substrate WF based on the measured value of the contact force measurement sensor 460. Using the contact force measurement sensor 460, the foreign matter remover 240 can prevent the brush 440 from damaging the substrate WF by pressing the substrate with a strong force.
[0091] The contact force measurement sensor 460 can be installed on the shaft 430. The contact force measurement sensor 460 can be disposed below the brush 440 to measure a load. For example, the contact force measurement sensor 460 can be a load cell. Figure 17 is a tenth example view for illustrating a foreign matter remover of a substrate cleaning apparatus according to some embodiments of the disclosure.
[0092] When both the upper surface and the lower surface of the substrate WF are cleaned, the first liquid supplier 220 can be used to clean the upper surface of the substrate WF, and the second liquid supplier 230 and the foreign matter remover 240 can be used to clean the lower surface of the substrate WF. That is, the foreign matter remover 240 can be used only to clean the lower surface of the substrate WF. However, embodiments of the disclosure are not limited thereto. The foreign matter remover 240 can be used not only to clean the lower surface of the substrate WF but also to clean the upper surface of the substrate WF. In this case, a plurality of foreign matter removers 240 can be provided, and the foreign matter removers 240 can be respectively disposed at a vertical height higher than the vertical height of the substrate support 210 and at a vertical height lower than the vertical height of the substrate support 210. Alternatively, the foreign matter remover 240 disposed at the vertical height lower than the vertical height of the substrate support 210 can be used to clean the lower surface of the substrate WF and then can be used to clean the upper surface of the substrate WF.
[0093] The foreign matter remover 240 can further include a drain cup 450. Referring to Figure 18 The drain cup 450 can be disposed below the brush 440. Water can be stored in the drain cup 450. As described before, the brush 440 can perform a flipping motion and a vertical motion. The brush 440 can normally (when the lower surface of the substrate WF is cleaned) move in or out of the drain cup 450 and can retain moisture stored in the drain cup 450. Even when a water film is not normally formed on the lower surface of the substrate WF, the brush 440 can minimize friction with the surface of the substrate WF. In addition, the water stored in the drain cup 450 can wash foreign matter adsorbed to the brush 440. The water from which the foreign matter has been washed off the brush 440 can be discharged to the outside, and new water can flow into the drain cup 450. Figure 18is a first example diagram for illustrating a substrate cleaning apparatus according to some embodiments of the disclosure.
[0094] The substrate cleaning apparatus 200 can use the second liquid supplier 230 and the foreign matter remover 240 continuously while cleaning the lower surface of the substrate WF. However, embodiments of the disclosure are not limited thereto. The substrate cleaning apparatus 200 can use the second liquid supplier 230 and the foreign matter remover 240 simultaneously during one partial cycle, and can use only the second liquid supplier 230 during another partial cycle. Alternatively, the simultaneous use of the second liquid supplier 230 and the foreign matter remover 240 and the use of only the second liquid supplier 230 can be repeated while cleaning the lower surface of the substrate WF.
[0095] Referring to Figure 19 , the substrate cleaning apparatus 200 can further include a first gas supplier 510 and a second gas supplier 520. Figure 19 is a second example diagram for illustrating an internal structure of a substrate cleaning apparatus according to some embodiments of the disclosure.
[0096] The first gas supplier 510 and the second gas supplier 520 can supply gas to the surface of the substrate WF. The first gas supplier 510 and the second gas supplier 520 can supply gas to different surfaces of the substrate WF, respectively. For example, the first gas supplier 510 can supply gas to the upper surface of the substrate WF, and the second gas supplier 520 can supply gas to the lower surface of the substrate WF.
[0097] The substrate cleaning apparatus 200 can perform a drying process after a cleaning process. The substrate cleaning apparatus 200 can use the first liquid supplier 220, the second liquid supplier 230, and the foreign matter remover 240 when performing the cleaning process. The substrate cleaning apparatus 200 can remove foreign matter from the surface of the substrate WF by the cleaning process. The substrate cleaning apparatus 200 can use the first gas supplier 510 and the second gas supplier 520 when performing the drying process. The substrate cleaning apparatus 200 can remove moisture from the surface of the substrate WF by the drying process.
[0098] The first gas supplier 510 and the second gas supplier 520 can supply the same type of gas. For example, the first gas supplier 510 and the second gas supplier 520 can supply nitrogen gas N2. However, embodiments of the disclosure are not limited thereto, and the first gas supplier 510 and the second gas supplier 520 can also supply different types of gas, respectively. The first gas supplier 510 can supply a first gas, and the second gas supplier 520 can supply a second gas. The first gas and the second gas can not react with each other, and can be suitable gases for removing moisture from the surface of the substrate WF.
[0099] The substrate cleaning apparatus 200 can dry the upper surface and the lower surface of the substrate WF at the same time. In this case, the first gas supplier 510 and the second gas supplier 520 can supply the gas at the same time. The substrate cleaning apparatus 200 can sequentially dry the upper surface and the lower surface of the substrate WF. In this case, the first gas supplier 510 and the second gas supplier 520 can sequentially supply the gas. Each of the first gas supplier 510 and the second gas supplier 520 can be formed to have a length direction that is not parallel to the width direction D1 or D2 of the substrate WF. For example, each of the first gas supplier 510 and the second gas supplier 520 can be formed to have a length direction that is inclined with respect to the width direction D1 or D2 of the substrate WF. However, embodiments of the disclosure are not limited thereto, and each of the first gas supplier 510 and the second gas supplier 520 can also be formed to have a length direction that is perpendicular to the width direction D1 or D2 of the substrate WF (for example, the direction D3). The first gas supplier 510 can have the same length direction as the length direction of the second gas supplier 520, or can have a length direction different from the length direction of the second gas supplier 520. According to an embodiment, the length direction can be a central axis along which the first gas supplier 510 or the second gas supplier 520 outputs the gas.
[0100] According to an embodiment, the substrate cleaning apparatus 200 can include the first gas supplier 510, and can not include the second gas supplier 520. When the substrate cleaning apparatus 200 performs the drying process, the upper surface of the substrate WF can be dried by the gas supplied from the first gas supplier 510, and the lower surface of the substrate WF can be naturally dried. Alternatively, the substrate cleaning apparatus 200 can also include the second gas supplier 520, and can not include the first gas supplier 510. When the substrate cleaning apparatus 200 performs the drying process, the upper surface of the substrate WF can be naturally dried, and the lower surface of the substrate WF can be dried by the gas supplied from the second gas supplier 520.
[0101] Referring to Figure 20 , the substrate cleaning apparatus 200 can further include a third liquid supplier 530. Figure 20 is a third example view for illustrating an internal structure of a substrate cleaning apparatus according to some embodiments of the disclosure.

The first liquid supplier 220 can supply a first liquid, and the third liquid supplier 530 can supply a third liquid. Each of the first liquid supplier 220 and the third liquid supplier 530 can be disposed at a vertical height higher than a vertical height of the substrate WF. The first liquid and the third liquid can be liquids different from each other. For example, the first liquid can be a chemical, and the third liquid can be deionized water. For example, the chemical can be isopropyl alcohol.
[0103] The first liquid supplier 220 and the third liquid supplier 530 can supply a liquid when cleaning the upper surface of the substrate WF. The first liquid supplier 220 and the third liquid supplier 530 can supply a liquid at the same time. However, embodiments of the disclosure are not limited thereto, and only one liquid supplier among the first liquid supplier 220 and the third liquid supplier 530 can supply a liquid.
[0104] According to an embodiment, the substrate cleaning device 200 can further include at least one gas supplier among the first gas supplier 510 and the second gas supplier 520 and the third liquid supplier 530.
[0105] Referring to Figure 21 , the substrate cleaning device 200 can further include a fourth liquid supplier 540. Figure 21 is a fourth example view for illustrating an internal structure of a substrate cleaning device according to some embodiments of the disclosure.
[0106] Like the first liquid supplier 220, the fourth liquid supplier 540 can supply a liquid to the upper surface of the substrate WF. The first liquid supplier 220 and the fourth liquid supplier 540 can supply a liquid of the same type. For example, the first liquid supplier 220 and the fourth liquid supplier 540 can supply deionized water.
[0107] The fourth liquid supplier 540 can supply a liquid at a time different from a time at which the first liquid supplier 220 supplies a liquid. A period in which cleaning of the substrate WF is performed can be divided into a first period and a second period. The first liquid supplier 220 can supply a liquid during the first period which is a first half period, and the fourth liquid supplier 540 can supply a liquid during the second period which is a second half period.
[0108] The fourth liquid supplier 540 can supply a liquid in a discharge scheme different from a scheme in which the first liquid supplier 220 discharges a liquid. Referring to Figure 22 , the first liquid supplier 220 can supply a liquid in an atomization scheme. Referring to Figure 23The fourth liquid supplier 540 can provide liquid in a dripping scheme. In this regard, the dripping scheme refers to a scheme of continuously discharging liquid droplets of a certain size to a narrow range of a destination. The atomizing scheme refers to a scheme of spraying liquid droplets of a fine size (i.e., liquid droplets of a size smaller than that of the liquid droplets in the dripping scheme) to a broad range of a destination. The first liquid supplier 220 can be provided as an aerosol nozzle. Figure 22 is a first exemplary diagram for illustrating a liquid supplier of a substrate cleaning apparatus according to some embodiments of the present disclosure. Figure 23 is a second exemplary diagram for illustrating a liquid supplier of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0109] According to embodiments, the substrate cleaning apparatus 200 can further include at least one gas supplier among the first gas supplier 510 and the second gas supplier 520 in addition to the fourth liquid supplier 540. Alternatively, the substrate cleaning apparatus 200 can further include the third liquid supplier 530 in addition to including the fourth liquid supplier 540. Alternatively, the substrate cleaning apparatus 200 can further include at least one gas supplier among the first gas supplier 510 and the second gas supplier 520, the third liquid supplier 530, and the fourth liquid supplier 540.
[0110] Referring to Figure 24 , the substrate cleaning apparatus 200 can further include a collector 550 and a vertical moving device 560. Figure 24 is a fifth exemplary diagram for illustrating an internal structure of a substrate cleaning apparatus according to some embodiments of the present disclosure.
[0111] The collector 550 can be disposed to surround the substrate support 210 and the substrate WF mounted on the top thereof. The collector 550 can collect liquid used to clean the substrate WF. While the substrate WF is fixed on the substrate support 210, the substrate support 210 is rotated. In this case, the first liquid supplier 220 can discharge liquid onto the substrate WF. The liquid discharged onto the substrate WF can splash toward the collector 550 due to a centrifugal force generated by the rotation of the substrate support 210. The collector 550 can collect the liquid dispersed in all directions through an inlet 551. The collector 550 can be provided as a bowl.
[0112] The vertical movement device 560 can move the collector 550 vertically. The vertical movement device 560 can adjust the vertical height of each of the collector 550 and the inlet 551 so that liquid dispersed in all directions can flow into the inlet 551 of the collector 550. The vertical movement device 560 can appropriately adjust the vertical height of each of the collector 550 and the inlet 551 in consideration of the vertical distance from each of the collector 550 and the inlet 551 to the substrate WF and the angle at which liquid is splashed from the substrate WF. The vertical movement device 560 can move the substrate support 210 vertically without moving the collector 550 vertically. Alternatively, the vertical movement device 560 can move one or more (e.g., some or all) of the collector 550, the inlet 551, and the substrate support 210 vertically.
[0113] According to embodiments of the present disclosure, the vertical movement device 560 can include at least one actuator for moving one or both of the collector 550 and the substrate support 210.
[0114] When the first liquid supplier 220 and the second liquid supplier 230 respectively supply different liquids, the collector 550 can be provided as two collection tubes. Similarly, even when the first liquid supplier 220 and the third liquid supplier 530 respectively supply different liquids, the collector 550 can be provided as two collection tubes.
[0115] Each of the first collection tube and the second collection tube among the two collection tubes can be provided in a ring shape. The first collection tube can be installed to surround the substrate support 210. The other of the two collection tubes (i.e., the second collection tube) can be installed to surround the first collection tube. The collector 550 can be configured so that different collection tubes respectively collect different liquids so that reuse of each liquid can be achieved.
[0116] When cleaning the lower surface of the substrate WF, a chemical reaction caused by a chemical solution and a physical rotational force acting on the substrate WF can be used to remove foreign substances from the lower surface of the substrate WF. However, in this method, the cleaning power on the central portion of the substrate WF and the cleaning power on the edge portion of the substrate WF can be different from each other. Accordingly, in the comparative embodiment, this method has limitations in removing foreign substances strongly adhered to the surface of the substrate WF.
[0117] According to some example embodiments of the present disclosure, the foreign substance remover 240 including the brush 440 can be used so that foreign substances strongly adhered to the lower surface of the substrate WF can be completely removed and the entire area of the substrate WF can be uniformly cleaned.
[0118] According to some example embodiments of the present disclosure, the substrate processing system 100 can also include a controller configured to cause the substrate processing system 100 to perform its functions. For example, the controller can be configured to cause the components of the substrate processing system 100 (e.g., the EFEM 110, the buffer chamber 120, the substrate cleaning device 200, the transfer module, the load lock chamber 140, and / or the processing chamber) to perform their respective functions.
[0119] According to some example embodiments of the present disclosure, the controller can be wholly or partially within one or more (e.g., some or all) of the components (e.g., the EFEM 110, the buffer chamber 120, the substrate cleaning device 200, the transfer module, the load lock chamber 140, and / or the processing chamber).
[0120] According to some example embodiments of the present disclosure, the controller can include at least one processor and a memory storing computer instructions. The computer instructions can be configured to cause the controller to perform its functions when executed by the at least one processor.
[0121] While non-limiting example embodiments of the present disclosure have been described with reference to the drawings, embodiments of the present disclosure are not limited to the example embodiments and can be implemented in various different forms. Embodiments of the present disclosure can be practiced in other specific forms without departing from the spirit and scope of the present disclosure. Therefore, it should be understood that the example embodiments as described above are in all aspects illustrative and not restrictive.
