[0027] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.
[0028] Referring to Figures 1 to 4 As shown, it shows an embodiment of the temperature control device and the thin film deposition equipment of the present utility model. The temperature control device includes a pipeline 110 assembly 10 and a temperature control assembly 20. The pipeline 110 assembly 10 includes a pipeline 110 and a base 120. The pipeline 110 is connected to a plasma generating device 30 and a reaction chamber. The base 120 is sleeved outside the pipeline 110, and a temperature control chamber 130 is formed between the base 120 and the pipeline 110. The temperature control assembly 20 includes a cold water device 210. Both ends of the cold water device 210 are respectively communicated with both sides of the temperature control chamber 130, and the cold water device 210 and the temperature control chamber 130 form a cold water loop. Among them, when performing the cleaning work, cold water flows along the cold water loop.
[0029] Specifically, when the thick film process is running in the thin film deposition equipment, the wafer needs to be cleaned first and then deposited to form a thick film on the wafer surface. However, when the thin film deposition equipment performs the cleaning work, since the plasma runs in the pipeline 110 of the thin film deposition equipment for a long time, the temperature of the pipeline at the bottom of the plasma generating device is too high, resulting in uneven growth of aluminum fluoride built on the spray plate and the heating plate, and further resulting in a change in the overall radio frequency impedance in the chamber, making the quality of the wafer coating poor. Therefore, the temperature control device is fixedly arranged on the thin film deposition equipment to control the pipeline temperature of the thin film deposition equipment.
[0030] In this embodiment, the thin film deposition equipment includes a plasma generating device 30 for generating plasma. The plasma generating device 30 is arranged above the workbench. The thin film deposition equipment further includes two reaction chambers. The reaction chambers are arranged inside the workbench. One of the reaction chambers is used for cleaning the wafer, that is, the cleaning work of the thin film deposition equipment is mainly carried out in this reaction chamber, and the other reaction chamber is used for depositing the thin film, that is, the deposition work of the thin film deposition equipment is mainly carried out in the other reaction chamber. The plasma generating device 30 and the reaction chambers are communicated through the pipeline 110 assembly 10, that is, the plasma generating device generates plasma, and the plasma enters the reaction chambers along the pipeline 110 assembly 10.
[0031] More specifically, the pipeline 110 assembly 10 includes a pipeline 110 and a base 120. The pipeline 110 connects a plasma generating device 30 and a reaction chamber. The pipeline 110 is provided at the bottom of the plasma generating device 30 and is located inside the workbench. One end of the pipeline 110 is connected to the bottom end of the plasma generating device 30, and the other end extends downward and then extends toward the two reaction chambers respectively and is connected to the two reaction chambers respectively. Where the pipeline 110 extends toward the two reaction chambers respectively forms a bifurcation of the pipeline 110; the base 120 is sleeved outside the pipeline 110, and the base 120 is located at the bifurcation of the pipeline 110. A temperature control chamber 130 is formed between the base 120 and the pipeline 110. The temperature control chamber 130 is used to adjust the temperature of the pipeline 110. The base 120 and the pipeline 110 are of an integral structure.
[0032] The temperature control device further includes a temperature control component 20. The temperature control component 20 includes a cold water device 210. Two ends of the cold water device 210 are respectively communicated with two sides of the temperature control chamber 130, so that the cold water device 210 and the temperature control chamber 130 form a cold water loop. The cold water device 210 is used to divert cold water into the temperature control chamber 130 and make the cold water circulate in the cold water device 210 and the temperature control chamber 130.
[0033] Refer to Figure 2 and Figure 3 As shown, when the thin film deposition equipment performs a cleaning operation, cold water flows in the cold water device 210 and the temperature control chamber 130 along the cold water loop, thereby cooling the base 120 and the pipeline 110 inside the base 120 to reduce the temperature of the pipeline 110, and further reducing the temperature of the plasma inside the pipeline 110, so as to avoid the plasma having too high a temperature. When the thin film deposition equipment performs a cleaning operation, it plays a role in inhibiting the growth of aluminum fluoride, making the growth of aluminum fluoride uniform, so that the rate of wafer thin film deposition remains stable, and the uniformity of the deposited thin film is high, so as to improve the product quality; on the other hand, the cold water reduces the temperature of the pipeline 110 and the base 120, thereby avoiding the phenomenon of corrosion of the rubber ring inside the thin film deposition equipment and improving the service life of the rubber ring; at the same time, it avoids the problems that the process performance stability of the thin film deposition equipment is affected due to the too high temperature at the bottom of the plasma generating device 30, and the maintenance cycle of the thin film deposition equipment is shortened and the maintenance cost is high.
[0034] In this application, a temperature control chamber 130 is provided between the pipeline 110 and the base 120, and a cold water device 210 is communicated with both sides of the temperature control chamber 130, so that the cold water device 210 and the temperature control chamber 130 form a cold water circuit. When the thin film deposition equipment starts the cleaning work, cold water flows along the cold water circuit, thereby cooling the pipeline 110 and the base 120 in the temperature control chamber 130 to stabilize the stability of thin film deposition, so as to ensure the uniformity of the deposited thin film and improve the product quality.
[0035] In one embodiment, referring to Figures 1 to 4 As shown, the temperature control component 20 further includes a hot water device 220. Both ends of the hot water device 220 are communicated with both sides of the temperature control chamber 130, and the hot water device 220 and the temperature control chamber 130 form a hot water circuit. Among them, when performing the deposition work, hot water flows along the hot water circuit. Specifically, the temperature control component 20 further includes a hot water device 220, and the hot water device 220 is used to divert hot water to the temperature control chamber 130 to heat the pipeline 110; both ends of the hot water device 220 are communicated with both sides of the temperature control chamber 130 respectively, so that the hot water device 220 and the temperature control chamber 130 form a hot water circuit, and the hot water device 220 is used to divert hot water into the temperature control chamber 130 and make the hot water circulate in the hot water device 220 and the temperature control chamber 130.
[0036] Referring to Figure 1 and Figure 4 As shown, when the thin film deposition equipment performs the deposition work, hot water flows in the hot water device 220 and the temperature control chamber 130 along the hot water circuit, thereby heating the base 120 and the pipeline 110 inside the base 120 to increase the temperature of the pipeline 110, and further increase the temperature of the plasma inside the pipeline 110, so as to avoid the low temperature of the plasma. When the thin film deposition equipment performs the deposition work, during the thin film deposition process, the plasma generating device 30 is in a non-working state. Continuing to pass cold water will reduce the overall temperature of the pipeline 110 and affect the vaporization state of the liquid source. At this time, the thin film deposition equipment introduces a heat source at a certain temperature during the thin film deposition process, that is, the hot water circulates in the hot water circuit to heat the pipeline 110, ensure the stability of the overall temperature of the pipeline 110, make the deposition process stable, and improve the product quality.

And the two water delivery pipes 140 are respectively communicated with two sides of the temperature control chamber 130. Specifically, the cold water device 210 includes a cold water pipe 211, the hot water device 220 includes a hot water pipe 221. The cold water pipe 211 and the hot water pipe 221 are respectively used for guiding cold water or hot water, that is, the cold water pipe 211 and the hot water pipe 221 are respectively used for inputting cold water or hot water into the temperature control chamber 130 and outputting the cold water or hot water in the temperature control chamber 130. The pipe 110 assembly 10 further includes two water delivery pipes 140. One ends of the two water delivery pipes 140 are both fixedly connected to the cold water pipe 211 and the hot water pipe 221. The other ends of the two water delivery pipes 140 are both fixedly connected to two sides of the base 120. That is, the ends of the water delivery pipes 140 connected to the cold water pipe 211 and the hot water pipe 221 are located above the workbench, and the other ends of the water delivery pipes 140 connected to the base 120 are located inside the workbench. The water delivery pipes 140 are used for connecting the cold water pipe 211, the hot water pipe 221 and the base 120. And the cold water pipe 211 or the hot water pipe 221 is communicated with the temperature control chamber 130, so that the cold water or hot water in the cold water pipe 211 or the hot water pipe 221 flows to the temperature control chamber 130 through the water delivery pipes 140.
[0038] In this application, the cold water pipe 211, the hot water pipe 221 and the temperature control chamber 130 are communicated through the water delivery pipes 140, which improves the structural stability of the temperature control device. And the connection parts of the cold water pipe 211, the hot water pipe 221 and the water delivery pipes 140 are located above the workbench, and the other ends of the water delivery pipes 140 are fixedly connected to the base 120 inside the workbench. Therefore, when connecting the cold water pipe 211, the hot water pipe 221 and the base 120, it is only necessary to connect the cold water pipe 211 and the hot water pipe 221 to the water delivery pipes 140. The connection method is simple and fast, and the connection is stable.
[0039] In a specific embodiment, the water delivery pipe 140 includes a first connection section and a second connection section (not shown in the figure). The first connection section and the second connection section are perpendicularly connected. One end of the first connection section is connected to the cold water pipe 211 and the hot water pipe 221, and one end of the second connection section is connected to the base 120. Specifically, one end of the water delivery pipe 140 is fixedly connected to the cold water pipe 211 and the hot water pipe 221, and the other end of the water delivery pipe 140 is fixedly connected to the base 120. One end of the water delivery pipe 140 is located above the workbench, and the other end of the water delivery pipe 140 is located inside the workbench.

The first connection section and the second connection section are perpendicularly connected, and one end of the first connection section is fixedly connected to the cold water pipe 211 and the hot water pipe 221. One end of the second connection section is fixedly connected to the base 120, that is, the second connection section is fixedly connected to the base 120 parallel to the workbench, and the first connection section extends perpendicularly to the second connection section above the workbench to be fixedly connected to the cold water pipe 211 and the hot water pipe 221. Cold water or hot water flows from the cold water pipe 211 or the hot water pipe 221 to the first connection section and the second connection section and then into the temperature adjustment chamber 130. The water delivery pipe 140 has a 90° structure to connect the base 120, the cold water pipe 211, and the hot water pipe 221. The structure of the water delivery pipe 140 is stable, and it is convenient to arrange one end of the water delivery pipe 140 inside the workbench and the other end outside the workbench, so that the connection structure of the cold water pipe 211, the hot water pipe 221, the base 120, and the water delivery pipe 140 has high stability, thereby improving the structural stability of the temperature adjustment device.

Specifically, one end of the water delivery pipe 140 away from the base 120 is respectively connected to the cold water pipe 211 and the hot water pipe 221. Therefore, the cold water pipe 211 and the hot water pipe 221 are connected to the water delivery pipe 140.

[0042] In this embodiment, the reversing valve 141 is fixedly provided at one end of the water delivery pipe 140 away from the base 120.

[0048] Refer to Figure 1 and Figure 4As shown, when the film deposition equipment performs deposition work, the three-way valve 234 of the cold water device 210 closes the port connected to the water inlet pipe 241 and the three-way valve 234, opens the port connected to the second circulation pipe 233 and the three-way valve 234, and opens the port connected to the first circulation pipe 232 and the three-way valve 234, so that cold water circulates in the water collecting member 231, the first circulation pipe 232 and the second circulation pipe 233, that is, the cold water does not flow to the water delivery pipe 140; at the same time, the three-way valve 234 of the hot water device 220 closes the port connected to the first circulation pipe 232 and the three-way valve 234, opens the port connected to the second circulation pipe 233 and the three-way valve 234, and opens the port connected to the water inlet pipe 241 and the three-way valve 234, so that hot water circulates in the direction from the water collecting member 231 along the second circulation pipe 233, the water inlet pipe 241, the water delivery pipe 140 and the water outlet pipe 242 and then back to the water collecting member 231, so as to heat up the pipeline 110 and the base 120 with hot water. That is, at this time, the cold water device 210 is in the closed state, the hot water device 220 is in the open state, and the hot water flows from the water collecting member 231 into the second circulation pipe 233 to the water inlet pipe 241 and the water delivery pipe 140, and flows to the temperature control chamber 130, and finally flows from the temperature control chamber 130 to the water outlet pipe 242 and finally to the water collecting member 231, so as to circulate.
[0049] In this application, by setting the first circulation pipe 232, the second circulation pipe 233 and the three-way valve 234, cold water or hot water can circulate in the water delivery assembly. Thus, when the cold water device 210 is controlled to be closed, the hot water device 220 circulates along the hot water circuit; when the hot water device 220 is controlled to be closed, the cold water device 210 circulates along the cold water circuit. The structures of the cold water device 210 and the hot water device 220 are simple, and the control accuracy is high, and the temperature control function of cooling or heating the base 120 can be realized.
[0050] In an embodiment, the water inlet pipe 241 and the water outlet pipe 242 are flexible hoses; and / or, the water delivery pipe 140 is a rigid pipe. Specifically, the water inlet pipe 241 and the water outlet pipe 242 are arranged above the workbench. A part of the water delivery pipe 140 is located inside the workbench, and the other part is located above the workbench. In this embodiment, the water inlet pipe 241 and the water outlet pipe 242 are made of flexible hose material, so that the positions of the water inlet pipe 241 and the water outlet pipe 242 are convenient to set and the applicability is higher; and / or, the water delivery pipe 140 is made of rigid pipe material. The water delivery pipe 140 has high hardness, so that the connection between the water inlet pipe 241 and the water outlet pipe 242 and the water delivery pipe 140 is more stable and the structure is more reliable.
[0051] This embodiment also provides a thin film deposition device (not shown in the figure). The thin film deposition device includes a temperature regulating device, and the temperature regulating device can adopt any one of the temperature regulating devices provided by the present utility model. Since the specific structure and working principle of the temperature regulating device have been introduced in detail in the previous description, for the sake of simplicity of the description, it will not be repeated here.
[0052] In the thin film deposition device of this embodiment, due to the adoption of the temperature regulating device provided by the present utility model, the temperature of the pipeline 110 can be adjusted to control the temperature of the plasma, so that when the thin film deposition device performs the cleaning work, the temperature of the pipeline 110 and the base 120 can be reduced, avoiding the problem that the growth of aluminum fluoride on the spray plate and the heating plate in the chamber affects the process repeatability due to the long-term operation of the thin film deposition device. Finally, the quality of the products produced by the thin film deposition device is improved. At the same time, the equipment maintenance cycle can be extended on the thin film deposition device, the production capacity can be increased, and the temperature can be reduced to protect the sealing rubber ring of the thin film deposition device, improving the service life of related hardware; and during the thin film deposition process, the plasma generating device 30 is in a non-working state, and continuously passing cold water will reduce the overall temperature of the pipeline 110, affecting the vaporization state of the liquid source. At this time, a heat source at a certain temperature is introduced during the film deposition process of the equipment to ensure the stability of the overall temperature of the pipeline 110.
