Abstract
Description
Technical Field
[0001] This application relates to the field of semiconductor technology, specifically to a robotic arm, a semiconductor device, and a method for adjusting the robotic arm. Background Technology
[0002] In the semiconductor field, electroplating refers to the process of depositing a thin metal film on a substrate. In advanced packaging technology, electroplating is commonly used to form different structures such as copper pillars and solder joints on the substrate to achieve chip interconnection.
[0003] Electroplating equipment is semiconductor equipment used to perform electroplating processes. Electroplating equipment includes an electroplating chamber and fixtures, as well as a robotic arm capable of placing or removing substrates from the fixtures. After the robotic arm removes the substrate from the Equipment Front End Module (EFEM) or the cleaning structure, it places the substrate into the fixture. Once the fixture secures the substrate, the surface of the substrate to be electroplated is immersed in the electroplating solution within the electroplating chamber to perform the electroplating process. After electroplating is complete, the robotic arm removes the substrate from the fixture.
[0004] like Figure 1 , Figure 2 and Figure 3 As shown, the clamp 200 in the electroplating equipment generally has an openable structure. The upper structure 201 of the clamp 200 can move upward to form an opening 203 with the lower structure 202. The robot can place the substrate at the bottom of the lower structure 202 through the opening 203. Then, the upper structure 201 of the clamp 200 moves downward to contact the substrate and apply downward pressure, so that the edge of the downward-facing surface of the substrate to be electroplated is fixed on the annular sealing ring 204 at the bottom.
[0005] The lower structure 202 of the fixture 200 includes an annular wall, with an annular sealing ring 204 disposed below the wall and an annular protruding wall 2021 disposed above the wall. The protruding wall 2021 has a certain width and a certain height from the surface of the protruding wall 2021 to the surface of the annular sealing ring 204. When the robot arm places a substrate into or removes a substrate from the opening 203 of the fixture 200, two conditions must be met: first, the robot arm must not interfere with the protruding wall 2021; and second, the robot arm must be able to enter the bottom of the lower structure 202 to place or remove the substrate.
[0006] In existing related technologies, the adsorption part of the robotic arm is connected to a vacuum tube via a connector, and the vacuum tube is connected to a fixing part via another connector. The adsorption part includes an adsorption end capable of adsorbing a substrate. However, with this structure, if the position of the adsorption end needs to be adjusted, the required length of the new vacuum tube needs to be determined and the current vacuum tube replaced with a new one. Therefore, the adjustment process is relatively cumbersome, time-consuming, and labor-intensive. Furthermore, the method of connecting the two ends of the vacuum tube with connectors results in poor sealing and easy air leakage, which may cause the adsorption end to fail to adsorb the substrate, or cause the substrate adsorbed on the adsorption end to fall off. Summary of the Invention

The method for adjusting the robotic arm includes: moving the movable part of the robotic arm relative to the fixed part of the robotic arm to change the extension length of the movable part, so that the outer convex wall portion of the receiving groove of the clamp extends into the through groove of the movable part, thereby placing a substrate in the clamp or removing a substrate from the clamp after the movable part and the clamp are correspondingly matched; wherein, before and after the movable part moves relative to the fixed part, the substrate adsorption channel formed by the movable part and the fixed part is in a sealed state.

Figure 6 The image shows a magnified view of the robotic arm in region B.
[0038] like Figures 1-7 As shown, this application embodiment provides a robotic arm 100, which is disposed in a semiconductor device 300 and used to place a substrate into or remove a substrate from a clamp 200 of the semiconductor device 300. The robotic arm 100 includes a moving part 101 and a fixed part 102, which are sealed together. The moving part 101 has a through groove, and the clamp 200 has a receiving groove. The outer protruding wall 2021 of the receiving groove can partially extend into the through groove. The end of the moving part 101 is provided with an adsorption end 1011 capable of adsorbing a substrate. The adsorption end 1011 is provided with an adsorption hole 10111. The moving part 101 forms a through first air passage 1012, which communicates with the adsorption hole 10111. A second air passage 1021 is formed inside the fixing part 102. The second air passage 1021 communicates with the first air passage 1012 and with the adsorption hole 10111 through the first air passage 1012. The second air passage 1021, the first air passage 1012, and the adsorption hole 10111 form a substrate adsorption channel for adsorbing the substrate. The moving part 101 can move relative to the fixing part 102 to change the extension length of the moving part 101. After the outer convex wall 2021 of the receiving groove extends into the through groove, the moving part 101 is matched with the clamp 200 to place the substrate into the clamp 200 or remove the substrate from the clamp 200. Before and after the moving part 101 moves relative to the fixing part 102, the substrate adsorption channel formed by the moving part 101 and the fixing part 102 is in a sealed state.
[0039] For example, the substrate is a wafer.
[0040] For example, the movable part 101 and the fixed part 102 are sealed by a sealing ring.
[0041] For example, the second air passage 1021 can be connected to a vacuum pump. By drawing gas from the second air passage 1021, the vacuum pump can draw away the gas in the first air passage 1012 and the adsorption hole 10111, so that the adsorption hole 10111 generates suction to adsorb the substrate.
[0042] In the above embodiments, since the moving part 101 can move relative to the fixed part 102 to change the extension length of the moving part 101, and the substrate adsorption channel formed by the moving part 101 and the fixed part 102 is in a sealed state before and after the moving part 101 moves relative to the fixed part 102, the robot 100 provided in this application embodiment can freely and flexibly adjust the extension length of the moving part 101, thereby flexibly adjusting the position of the adsorption end 1011 so that after the outer convex wall 2021 of the receiving groove extends into the through groove, the moving part 101 and the clamp 200 can be matched accordingly and the substrate can be placed into or removed from the clamp 200 (through the adsorption end 1011) without replacing the vacuum tube, which is convenient, time-saving and labor-saving. Furthermore, since the substrate adsorption channel formed by the moving part 101 and the fixed part 102 can always be in a sealed state before and after the moving part 101 moves relative to the fixed part 102, the sealing performance of adjusting the extension length of the moving part 101 is guaranteed.
[0043] In some embodiments, such as Figure 6 and Figure 7As shown, the fixing part 102 has a first opening 1022 (located at the dotted line indicated by 1022) communicating with the second air passage 1021. The first air passage 1012 includes a first sub-air passage 10121 and a second sub-air passage 10122. The moving part 101 includes a vacuum connector 1013 and an adsorption assembly 1014. At least a portion of the vacuum connector 1013 extends into the second air passage 1021 through the first opening 1022. The vacuum connector 1013 has a first sub-air passage 10121 and a second opening 10131 and a third opening 10132 communicating with the first sub-air passage 10121. The second opening 10131 is located within the second air passage 1021, and the first sub-air passage 10121 communicates with the second air passage 1021 through the second opening 10131. The adsorption assembly 1014 has an adsorption hole 10111, a second sub-gas channel 10122, and a connecting hole 10141. The second sub-gas channel 10122 communicates with the adsorption hole 10111 and the connecting hole 10141. One end of the adsorption assembly 1014 with the connecting hole 10141 is connected to one end of the vacuum connector 1013 with the third opening 10132. The second sub-gas channel 10122 communicates with the first sub-gas channel 10121 through the connecting hole 10141 and the third opening 10132. That is, in a generally left-to-right direction, the adsorption hole 10111, the second sub-gas channel 10122, the connecting hole 10141, the third opening 10132, the first sub-gas channel 10121, the second opening 10131, and the second gas channel 1021 are sequentially connected to form a substrate adsorption channel. The robotic arm 100 also includes a first sealing member 103. The first sealing member 103 is disposed between the end face of the adsorption assembly 1014 having the connecting hole 10141 and the end face of the vacuum connector 1013 having the third opening 10132, and is disposed around the third opening 10132, and is configured to seal the gap between the third opening 10132 and the connecting hole 10141.
[0044] For example, the first seal 103 is an annular sealing ring.
[0045] In the above embodiments, by providing a first sealing member 103 between the end face of the adsorption component 1014 with the connecting hole 10141 and the end face of the vacuum connector 1013 with the third opening 10132, the gap between the third opening 10132 and the connecting hole 10141 can be sealed well to prevent air leakage.
[0046] In some embodiments, such as Figure 7 As shown, the robotic arm 100 further includes at least one second seal 104. The at least one second seal 104 is disposed between the inner wall of the second air passage 1021 and the outer side of the end of the vacuum connector 1013 having the second opening 10131, and is configured to seal the gap between the inner wall of the second air passage 1021 and the vacuum connector 1013.
[0047] For example, the second seal 104 is an annular sealing ring.
[0048] For example, there may be two, three or four second seals 104.
[0049] In the above embodiments, by providing a second sealing member 104 between the inner wall of the second air passage 1021 and the outer side of the end of the vacuum connector 1013 with the second opening 10131, the gap between the inner wall of the second air passage 1021 and the vacuum connector 1013 can be sealed well to prevent air leakage.
[0050] In some embodiments, such as Figure 7 As shown, there are multiple second seals 104, which are arranged sequentially along the extension direction of the vacuum connector 1013.
[0051] For example, there are two second seals 104, and two second seals 104 are arranged sequentially along the extension direction of the vacuum connector 1013.
[0052] In the above embodiments, by providing multiple second seals 104, the sealing performance between the inner wall of the second air passage 1021 and the vacuum connector 1013 can be improved. The more second seals 104 provided, the better the sealing performance between the inner wall of the second air passage 1021 and the vacuum connector 1013.
[0053] Figure 8 The image shown is an exemplary embodiment of this application. Figure 6 The image shows a magnified view of the robotic arm in region C.
[0054] In some embodiments, such as Figure 8 As shown, the maximum distance that the moving part 101 moves away from the fixed part 102 is the target distance between the second seal 104 closest to the first opening 1022 and the end face of the fixed part 102 having the first opening 1022, wherein the target distance ranges from 0 mm to 30 mm. Correspondingly, the maximum distance that the moving part 101 moves closer to the fixed part 102 is from 0 mm to 30 mm.
[0055] For example, the target distance is 10 mm, 20 mm or 30 mm.
[0056] In the above embodiments, by making the target distance range from 0 mm to 30 mm, the extension length of the moving part 101 can be flexibly adjusted so that the adsorption end 1011 can be inserted into the appropriate position in the clamp 200 to place or remove the substrate.
[0057] It should be understood that the above distance values are set in conjunction with the actual application field of the semiconductor device 300 in this embodiment. In different application fields, the position of the second seal 104 can be set according to the actual situation to change the target distance. For example, the target distance can be adjusted to different data such as 0 mm to 50 mm depending on the actual application.
[0058] In some embodiments, such as Figure 7 and Figure 8 As shown, the vacuum connector 1013 includes an insertion portion 10136 and an abutment portion 10137. The insertion portion 10136 extends at least partially into the second air passage 1021 through the first opening 1022. The abutment portion 10137 is located on the side of the insertion portion 10136 away from the fixing portion 102, and is located between the adsorption assembly 1014 and the fixing portion 102, and is connected to the insertion portion 10136. When the insertion portion 10136 is entirely within the second air passage 1021, and the abutment portion 10137 abuts against the fixing portion 102, the target distance is 30 mm. When the second sealing member 104 closest to the first opening 1022 and the end face of the fixing portion 102 having the first opening 1022 are positioned at the same position in the extending direction of the vacuum connector 1013, the target distance is 0 mm.
[0059] Specifically, in order for the second seal 104 to function as a seal, the second seal 104 cannot detach from the second air passage 1021 and must always remain between the inner wall of the second air passage 1021 and the vacuum connector 1013. Furthermore, if the abutting part 10137 abuts against the fixing part 102, the moving part 101 cannot move towards the fixing part 102. Therefore, when the inserting part 10136 is completely located in the second air passage 1021 and the abutting part 10137 abuts against the fixing part 102, the target distance is at its maximum (i.e., 30 mm). When the second seal 104 closest to the first opening 1022 and the end face of the fixing part 102 with the first opening 1022 are positioned in the same direction as the extension of the vacuum connector 1013, i.e., when the second seal 104 is about to detach from the second air passage 1021, the target distance is at its minimum (i.e., 0 mm). Correspondingly, the maximum distance that the moving part 101 can move towards the fixing part 102 is at its maximum (i.e., 30 mm).
[0060] In some embodiments, such as Figures 5-7As shown, the adsorption assembly 1014 includes: two clamping portions 10142, at least one first screwed member, and an adsorption portion 10143. The two clamping portions 10142 are respectively disposed on both sides of the end of the vacuum connector 1013 and the fixing portion 102 having a first opening 1022 in a first direction (i.e., the X direction in the figure). One clamping portion 10142 has at least one first through hole 101422 extending along the first direction, and the other clamping portion 10142 has at least one first threaded portion extending along the first direction, which is parallel to the end face of the fixing portion 102 having the first opening 1022. The first screwed member passes through the first through hole 101422 and is screwed to the first threaded portion. The adsorption portion 10143 is disposed on the side of the vacuum connector 1013 away from the fixing portion 102 and is connected to the two clamping portions 10142. The adsorption portion 10143 has an adsorption hole 10111, a second sub-air passage 10122, and a connecting hole 10141.
[0061] For example, the first direction is a horizontal direction that is perpendicular to the extension direction of the vacuum connector 1013.
[0062] For example, another clamping part 10142 has at least one first threaded hole 101421 extending in a first direction, the first threaded part being the thread within the first threaded hole 101421.
[0063] For example, the first threaded component is a screw or bolt.
[0064] For example, there are multiple first through holes 101422, which are arranged sequentially along a second direction (i.e., the Y direction in the figure) and / or, the multiple first through holes 101422 are arranged sequentially along a third direction (i.e., the Z direction in the figure). The first direction, the second direction, and the third direction intersect each other, such as the first direction, the second direction, and the third direction (such as the vertical direction) are perpendicular to each other. Correspondingly, there are multiple first threaded portions, which are arranged sequentially along the second direction and / or, the multiple first threaded portions are arranged sequentially along the third direction.
[0065] For example, one clamping part 10142 has two first through holes at one end in the third direction and two first through holes at the other end in the third direction. The two first through holes at the same end of the clamping part 10142 in the third direction are spaced apart along a second direction. Correspondingly, another clamping part 10142 has two first threaded portions at one end in the third direction and two first threaded portions at the other end in the third direction. The two first threaded portions at the same end of the other clamping part 10142 in the third direction are spaced apart along a second direction.
[0066] In the above embodiments, the moving part 101 and the fixed part 102 can be fastened together by the two clamping parts 10142 and at least one first screw connector.
[0067] Figure 9 The image shown is an exemplary embodiment of this application. Figure 7 The image shows a cross-sectional view of the robotic arm along the EE direction.
[0068] In some embodiments, such as Figure 9 As shown, the adsorption part 10143 has at least one second threaded portion adjacent to the connecting hole 10141 at one end. The second threaded portion extends along a second direction. A first sealing member 103 is disposed between the second threaded portion and the connecting hole 10141. The second direction intersects the first direction. The vacuum connector 1013 has at least one second through hole 10133 extending along the second direction. The adsorption assembly 1014 further includes at least one second screw connector 10144. The second screw connector 10144 passes through the second through hole 10133 and is screwed onto the second threaded portion.
[0069] For example, one end of the adsorption part 10143 having a connecting hole 10141 has at least one second threaded hole disposed adjacent to the connecting hole 10141, and the second threaded part is the thread inside the second threaded hole.
[0070] For example, the second screw connector 10144 is a screw or bolt.
[0071] For example, there are multiple second threaded portions, which are arranged around the first seal 103.
[0072] For example, the number of second threaded portions may be 2, 3, or 4.
[0073] In the above embodiments, the adsorption part 10143 and the vacuum connector 1013 can be fixed to each other by means of the second threaded part and the second screw connector 10144. By placing the first sealing member 103 between the second threaded part and the connecting hole 10141, instead of placing the second threaded part between the first sealing member 103 and the connecting hole 10141, air leakage at the location of the second threaded part can be avoided.
[0074] In some embodiments, the end face of the vacuum connector 1013 having a third opening 10132 has a first annular groove 10134 disposed around the third opening 10132, and the first seal 103 has an annular shape and is partially disposed in the first annular groove 10134.
[0075] In the above embodiments, by providing a first annular groove 10134 to accommodate at least a portion of the first seal 103, the first seal 103 can be securely fixed.
[0076] In some embodiments, the outer wall of the vacuum connector 1013 has a second annular groove 10135 disposed circumferentially along the vacuum connector 1013, and the second seal 104 is annular in shape and is partially disposed in the second annular groove 10135.
[0077] For example, if there are multiple second seals 104, and the multiple second seals 104 are arranged sequentially along the extension direction of the vacuum connector 1013, correspondingly, there are multiple second annular grooves 10135, and the multiple second annular grooves 10135 are arranged sequentially along the extension direction of the vacuum connector 1013, so that each second annular groove 10135 can accommodate at least a portion of a corresponding second seal 104.
[0078] In the above embodiments, by providing a second annular groove 10135 to accommodate at least a portion of the second seal 104, the second seal 104 can be securely fixed.
