Description

TECHNICAL FIELD

The present disclosure relates to the technical field of semiconductor manufacturing, in particular to an installation fixture for an electrode plate of a semiconductor equipment.

BACKGROUND

At present, in the technical field of semiconductors, the disassembly and assembly of an electrode plate of a semiconductor equipment usually requires at least two operators to complete, which wastes a lot of human resources. Meanwhile, during the mounting of the electrode plate, the operators are also required to manually align screws on the fixing disc with screw holes on the electrode plate. It is likely to cause the position of the lip seal ring on the fixing disc to deviate, thereby leading to leakage inside the cavity and ultimately affecting the etching of the semiconductor. In addition, the manual mounting by the operators is prone to bumps, which will cause damage to the electrode plate, thereby increasing the mounting cost of the electrode plate.

It should be noted that the information disclosed above is merely intended to facilitate a better understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

The exemplary embodiments are described more comprehensively below with reference to the drawings. The exemplary implementations may be implemented in various forms, and may not be construed as being limited to those described herein. On the contrary, these exemplary implementations are provided to make the present disclosure comprehensive and complete and to fully convey the concept manifested therein to those skilled in the art. The same reference numerals in the figures indicate the same or similar structures, and thus their detailed descriptions will be omitted.

The terms “a”, “an”, “the”, and “said” are used to indicate that there are one or more elements/components/etc. The terms “including” and “having” are used to mean open-ended inclusion and mean that there may be additional elements/components/etc. in addition to the listed elements/components/etc.

As shown in FIGS. 1 to 3, the present disclosure provides an installation fixture 2 for an electrode plate of a semiconductor equipment. The installation fixture 2 may include an alignment assembly, a drive assembly and a support assembly. The installation fixture 2 can realize the purpose of mounting an electrode plate 12 by a single person, thereby saving a lot of manpower resources and improving the mounting efficiency. Meanwhile, the installation fixture 2 of the present disclosure can also automatically align to prevent the impact on semiconductor etching due to the inaccurate alignment of the electrode plate 12. In addition, the installation fixture can also prevent damage to the electrode plate 12 due to a bump during manual mounting by an operator, thereby reducing the mounting cost of the electrode plate 12.

Further, as shown in FIGS. 2 and 3, the above-mentioned semiconductor equipment 1 may be provided with a fixing disc 11. The fixing disc 11 is used to mount the electrode plate 12. The fixing disc 11 may be provided with at least two positioning screws 111 and at least two fixing screws 112. It should be noted that the positioning screws 111 and the fixing screws 112 may be the same or different screws. Meanwhile, multiple lip seals may also be provided on the fixing disc 11 to seal and divide regions define by the fixing disc 11 and the electrode plate 12 so as to prevent leakage and mutual influence between different regions.

As shown in FIGS. 4 and 5, the electrode plate 12 may be provided with at least two positioning screw holes 121 and at least two fixing screw holes 122. The positioning screw holes 121 are matched with the positioning screws 111, and the fixing screw holes 122 are matched with the fixing screws 112. That is, the positioning screw holes 121 of the electrode plate 12 are connected to the positioning screws 111 of the fixing disc 11, so as to realize the positioning and connection of the electrode plate 12. The fixing screw holes 122 of the electrode plate 12 are connected to the fixing screws 112 of the fixing disc 11, so as to realize the connection and fixing of the electrode plate 12 to the fixing disc 11. It should be noted that the positioning screw holes 121 and the fixing screw holes 122 may be the same or different, which falls within the protection scope of the present disclosure.

Further, the electrode plate 12 may include an electrode 123 and a clamping ring 124. The electrode 123 may be mounted on the clamping ring 124, that is, the clamping ring 124 may be enclosed outside the electrode 123. For example, the electrode 123 and the clamping ring 124 may be integrally formed to define the electrode plate 12, but it is not limited thereto. The electrode 123 and the clamping ring 124 may also be manufactured separately. After the manufacturing of the electrode 123 and the clamping ring 124 is completed, they are connected together to form the electrode plate 12.

In an embodiment of the present disclosure, as shown in FIGS. 1 and 6 to 11, the alignment assembly may include a support disc 21 and at least two guide shafts 22. The support disc 21 may be provided with at least two positioning holes 211, at least two fixing holes 217 and at least two mounting holes 212. The positioning holes 211 may be aligned with the positioning screws 111 on the fixing disc 11, the fixing holes 217 may be aligned with the fixing screws 112 on the fixing disc 11, and the fixing screws 112 may pass through the fixing screw holes 122 and the fixing holes 217. After the electrode plate 12 is placed on the support disc 21, the positioning screw holes 121 and the fixing screw holes 122 on the electrode plate 12 are aligned with the positioning holes 211 and the fixing holes 217 on the support disc, respectively. Only by doing so, the positioning screw holes 121 are aligned with the positioning screws 111, and the fixing screw hole 122 are aligned with the fixing screws 112.

It should be noted that the number of the positioning holes 211 on the support disc 21 may be the same as that of the positioning screw holes 121 and that of the positioning screws 111. The number of the fixing holes 217 on the support disc 21 may be the same as that of the fixing screw holes 122 and that of the fixing screws 112. The diameter of the positioning holes 211 on the support disc 21 may be the same as that of the positioning screw holes 121.

The guide shafts 22 are able to pass through the positioning holes 211 and the positioning screw holes 121. One end of each of the guide shafts 22 may be provided with a positioning groove 221, and the positioning groove 221 is able to be connected to one of the positioning screws 111. Thus, the guide shafts 22 are able to be connected to the positioning screws 111 through positioning groove 221. The present disclosure does not limit the connection manner of the positioning grooves 221 and the positioning screws 111. For example, the positioning grooves 221 and the positioning screws 111 may be fixedly connected, or may be detachably connected. When the positioning grooves 221 are detachably connected to the positioning screws 111, the guide shafts 22 may be removed after the electrode plate 12 and the fixing disc 11 are aligned, so as to prevent the guide shafts 22 from affecting the operation of the semiconductor equipment. Meanwhile, after the guide shafts 22 are removed, the electrode plate 12 and the fixing disc may still be fixed by the positioning screws 111 and the positioning screw holes 121. That is, the positioning screws 111 and the positioning screw holes 121 function as the fixing screws 112 and the fixing screw holes 122, thereby making the fixing of the electrode plate 12 more stable and minimizing the number of the fixing screws 112 and the fixing screw holes 122.

Further, after the guide shafts 22 pass through the positioning screw holes 121 and the positioning holes 211, the electrode plate 12 may be further positioned. Thus, when the electrode plate 12 and the fixing disc 11 are finally fixed, the electrode plate 12 is prevented from deviating, so as to avoid the failure of the mounting of the electrode plate 12. It should be noted that the number of the guide shafts 22 may be the same as that of the positioning screws 111. The length of the guide shafts 22 may be greater than or equal to the total thickness of the electrode plate 12 and the fixing disc 11, and the diameter of the guide shafts 22 may be less than or equal to that of the positioning holes 211 and the positioning screw holes 121.

Preferably, the diameter of the guide shafts 22 may be slightly less than that of the positioning holes 211 and the positioning screw holes 121, such that the guide shafts 22 are transitionally fitted to the positioning holes 211 and the positioning screw holes 121. In this way, the electrode plate 12 is better positioned, ensuring that the alignment of the electrode plate 12 and the fixing disc 11 is more accurate.

As shown in FIGS. 12 to 17, the drive assembly may include a mounting plate assembly 31, at least two support rods 25 and a drive rod assembly 26. The support rods 25 may be connected to the mounting plate assembly 31, and one end of each of the support rods 25 may be connected to one of the mounting holes 212. It is understandable that connecting the support rods 25 to the mounting plate assembly 31 may enable the support rods 25 to move with the movement of the mounting plate assembly 31. One end of each of the support rods 25 may be fixedly connected to one of the mounting holes 212, or may be transitionally matched with one of the mounting holes 212, such that the support rods 25 drive the support disc 21 to move. However, the present disclosure does not limit the connection manner between one end of each of the support rods 25 and one of the mounting hole 212, as long as the support rods 25 can drive the support disc 21 to move, which falls within the protection scope of the present disclosure. In addition, the number of the support rods 25 may be the same as that of the mounting holes 212 or different from that of the mounting holes 212, which falls within the protection scope of the present disclosure.

The drive rod assembly 26 may also be connected to the mounting plate assembly 31 to drive the mounting plate assembly 31 to move and then to drive the support disc 21 to move, such that the electrode plate 12 on the support disc 21 moves toward the fixing disc 11.

As shown in FIGS. 18 to 20, the support assembly may include at least two support bases 28. The support bases 28 each may be provided with a mounting groove 281, and the other end of each of the support rods 25 may be located in the mounting groove 281. It is understandable that an end of each of the support bases 28 close to the mounting plate assembly 31 may be provided with one mounting groove 281, and may be connected to the other end of each of the support rods 25 through the mounting groove 281. It should be noted that when the drive assembly is at the highest position, the other end of each of the support rods 25 still needs to be located in the mounting groove 281. An end of each of the support bases 28 away from the mounting plate assembly 31 may be in contact with the ground to support the entire installation fixture 2.

Therefore, through the support of the support assembly, during the mounting of a motor plate, it is no longer necessary to manually hold the electrode plate 12. It only needs to place the electrode plate 12 on the support disc 21, thereby freeing both hands and saving labor. Meanwhile, the operator can only operate the drive rod assembly 26 to complete the alignment of the electrode plate 12 and the fixing disc 11, which further saves manpower and improves the mounting efficiency. In addition, the deviation of the lip seal rings due to the position deviation and the damage of the electrode plate 12 caused by manual mounting are prevented.

In an embodiment of the present disclosure, as shown in FIG. 8, the support disc 21 may further include snap ring guiders 213. The snap ring guiders 213 each may be provided with a first blocking portion 2131 and a first guiding portion 2132. The first blocking portion 2131 may be located at a periphery of the first guiding portion 2132 and may be connected to the first guiding portion 2132. The first blocking portion 2131 may be in contact with a side of the support disc 21 close to the mounting plate assembly 31. It is understandable that the first blocking portion 2131 is able to block the snap ring guider 213 from moving in a direction away from the mounting plate assembly 31. The first blocking portion 2131 may be composed of two blocking blocks or a blocking ring. The present disclosure does not limit the form of the first blocking portion 2131, as long as it can block the snap ring guider 213 from moving in the direction away from the mounting plate assembly 31, which falls within the protection scope of the present disclosure.

One end of the first guiding portion 2132 is able to pass through one of the positioning holes 211. The first guiding portion 2132 may be interference-fit with the positioning hole 211, but is not limited thereto. The first guiding portion 2132 and the positioning hole 211 may also be matched in other manners, depending on actual conditions.

Further, the first guiding portion 2132 may be provided with a through hole, and the guide shaft 22 is able to pass through the through hole. It is understandable that an extending direction of the through hole is the same as a moving direction of the guide shaft 22. In order to prevent the guide shaft 22 from damaging the support disc 21 when passing through the through hole, the length of the first guiding portion 2132 may be set to a value greater than the thickness of the support disc 21, such that an end of the first guiding portion 2132 away from the mounting plate assembly 31 is higher than the side of the support disc 21 away from the mounting plate assembly 31.

Further, when the end of the first guiding portion 2132 away from the mounting plate assembly 31 is higher than the side of the support disc 21 away from the mounting plate assembly 31, the first guiding portion 2132 is engaged with the positioning screw hole 121 on the electrode plate 12, such that the positioning screw hole 121 on the electrode plate 12 is more conveniently aligned with the positioning hole 211. This can also prevent the electrode plate 12 from deviating during movement after the positioning screw holes 121 of the electrode plate 12 are aligned with the positioning holes 211 on the support disc. However, it is not limited to this. The end of the first guiding portion 2132 away from the mounting plate assembly 31 may also be flush with the side of the support disc 21 away from the mounting plate assembly 31, or it may be lower than the side of the support disc 21 away from the mounting plate assembly 31, which falls within the protection scope of the present disclosure. In addition, the number of the snap ring guiders 213 may be the same as that of the positioning holes 211. That is, there is a snap ring guider 213 in each of the positioning holes 211.

In an embodiment of the present disclosure, as shown in FIG. 9, the support disc 21 may further include drive guiders 214. The drive guiders 214 each may be provided with a second blocking portion 2141 and a second guiding portion 2142. The second blocking portion 2141 may be located at a periphery of the second guiding portion 2142 and may be connected to the second guiding portion 2142. The second blocking portion 2141 may be in contact with the side of the support disc 21 close to the mounting plate assembly 31. It is understandable that the second blocking portion 2141 is able to block the drive guider 214 from moving in a direction away from the mounting plate assembly 31. The second blocking portion 2141 may be composed of two blocking blocks or a blocking ring. The present disclosure does not limit the form of the second blocking portion 2141, as long as it can block the drive guider 214 from moving in the direction away from the mounting plate assembly 31, which falls within the protection scope of the present disclosure.

The second guiding portion 2142 may be provided with a guiding groove 2143. The guiding groove 2143 is provided with an opening on a side close to the mounting plate assembly 31. An end of the second guiding portion 2142 away from the opening may pass through the mounting hole 212 and may be flush with the side of the support disc 21 away from the mounting plate assembly 31. The second guiding portion 2142 may be interference-fit with the mounting hole 212, but is not limited thereto. The present disclosure does not limit the matching manner between the second guiding portion 2142 and the mounting hole 212, which falls within the protection scope of the present disclosure. One end of the support rod 25 is connected to the guiding groove 2143 to realize the connection to the mounting hole 212. One end of the support rod 25 may be fixedly connected to the guiding groove 2143, or may be transitionally matched with the guiding groove 2143, as long as the support rod 25 can drive the support disc 21 to move, which falls within the protection scope of the present disclosure.

In addition, the number of the drive guiders 214 may be the same as that of the mounting holes 212, that is, the number of the drive guiders 214 may also be the same as that of the support rods 25.

In an embodiment of the present disclosure, as shown in FIG. 11, the alignment assembly may further include an engaging ring 215. The engaging ring 215 may be provided on the side of the support disc 21 away from the mounting plate assembly 31 and located at an edge of the support disc. The height of the engaging ring 215 may be equal to that of the clamping ring 124 of the electrode plate 12, so as to engage the electrode plate 12 and prevent the position of the electrode plate 12 from deviating during movement.

Further, as shown in FIG. 7, the alignment assembly may further include at least one engaging plate 216, and the engaging plate 216 may be provided with a connecting portion and an engaging portion. The connecting portion may be located on the side of the support disc 21 away from the mounting plate assembly 31 and may be connected to the support disc 21. The connecting portion may be provided with a connecting hole 2161, and orthographic projection of a center of the connecting hole 2161 and orthographic projection of a center of the fixing hole 217 may coincide with each other.

The engaging portion may be located on a side of the connecting portion close to a center of the support disc 21 and may be connected to the connecting portion to engage the electrode 123. Further, a side of the engaging portion close to the center of the support disc 21 may be an arc, so as to engage the electrode 123 through two corners of an arc-shaped edge. However, it is not limited to this. The arc may have the same radian as the electrode 123, so as to engage the electrode 123 better by the arc-shaped engaging portion.

In an embodiment of the present disclosure, as shown in FIGS. 13 and 16, the mounting plate assembly 31 may include a first mounting plate member 23 and a second mounting plate member 24. The first mounting plate member 23 may be located on a side of the drive assembly close to the support disc 21, and the second mounting plate member 24 may be located on a side of the drive assembly away from the support disc 21. The drive rod assembly 26 may pass through the second mounting plate member 24 and may be fixedly connected to the first mounting plate member 23. The support rods 25 may pass through the second mounting plate member 24 and may be connected to the first mounting plate member 23.

Further, the first mounting plate member 23 may be the same as the second mounting plate member 24, and orthographic projection of the first mounting plate member 23 and orthographic projection of the second mounting plate member 24 may coincide with each other.

In an embodiment of the present disclosure, as shown in FIG. 13, each of the support rods 25 may be provided with a rod portion 251 and a third blocking portion 252. One end of the rod portion 251 is able to pass through the first mounting plate member 23 and the second mounting plate member 24 and is connected to the guiding groove 2143. It should be noted that the diameter of the end of the support rod 25 connected to the guiding groove 2143 may be less than or equal to the inner diameter of the guiding groove 2143.

Further, in order to ensure a higher strength and a greater supporting force of the support rod 25, the diameter of other part of the support rod 25 may be greater than that of the end of the support rod 25 connected to the guiding groove 2143. The present disclosure does not limit the specific value of the diameter, and the diameter may be set according to actual needs.

The third blocking portion 252 may be located at a periphery of the rod portion 251 and may be connected to the rod portion 251, and the third blocking portion 252 may be in contact with a side of the first mounting plate member 23 close to the support disc 21. It is understandable that the third blocking portion 252 is able to block the support rod 25 from moving in a direction away from the support disc 21. The third blocking portion 252 may be composed of two blocking blocks or a blocking ring. The present disclosure does not limit the form of the third blocking portion 252, as long as it can block the support rod 25 from moving in the direction away from the support disc 21, which falls within the protection scope of the present disclosure.

In an embodiment of the present disclosure, as shown in FIG. 14, the drive rod assembly 26 may be provided with a drive rod 261 and a meshing device 262. An outer peripheral surface of the drive rod 261 may be provided with a first screw-thread, and one end of the drive rod 261 may be connected to the first mounting plate member 23. For example, one end of the drive rod 261 may be connected to the first mounting plate member 23 by a screw, but it is not limited to this. It may also be connected in other manners, which falls within the protection scope of the present disclosure. In addition, the present disclosure does not limit the specific size of the first screw-thread, which may be set according to actual needs.

The meshing device 262 may be provided with a meshing portion 2621. The meshing portion 2621 may pass through the second mounting plate member 24, and an inner surface of the meshing portion 2621 may be provided with a second screw-thread matched with the first screw-thread. The meshing portion 2621 may be meshed with the drive rod 261. When the drive rod 261 rotates, the drive rod 261 is displaced relative to the meshing portion 2621, so as to drive the first mounting plate member 23 to move, thereby driving the support disc 21 to move.

Further, the meshing portion 2621 may be interference-fit with the second mounting plate member 24 to prevent the meshing portion 2621 from falling off during the movement of the drive rod 261.

In order to further prevent the meshing portion 2621 from falling off, the meshing device 262 may also be provided with a fifth blocking portion 2622.

The fifth blocking portion 2622 may be composed of two blocking blocks or a blocking ring. The present disclosure does not limit the form of the fifth blocking portion 2622, as long as it can block the meshing device 262 from moving in the direction close to the support disc 21, which falls within the protection scope of the present disclosure.

Further, the drive rod assembly 26 may also be provided with a handle 263, and the handle 263 may be connected to an end of the drive rod 261 that is not connected to the first mounting plate member 23. The handle 263 makes it easier for the operator to turn the drive rod 261.

It should be noted that the drive assembly provided by the present disclosure may also be in other forms, such as hydraulic drive and electric drive, depending on actual needs, which falls within the protection scope of the present disclosure.

In an embodiment of the present disclosure, the drive assembly may further include at least one guide rod assembly 27. The guide rod assembly 27 may pass through the second mounting plate member 24 and may be fixedly connected to the first mounting plate member 23. In this way, it provides guidance for the movement of the first mounting plate member 23, so as to prevent the movement of the first mounting plate member 23 from deviating and make the movement of the first mounting plate member 23 smooth.

Further, as shown in FIG. 15, the guide rod assembly 27 may be provided with a guide rod 271 and a ball guider 272. The guide rod 271 may pass through the ball guider 272 and may be fixedly connected to the first mounting plate member 23. That is, an end of the guide rod 271 may be connected to the first mounting plate member 23. For example, the end of the guide rod 271 may be connected to the first mounting plate member 23 by a screw. However, it is not limited to this, and it may also be connected in other manners, which falls within the protection scope of the present disclosure.

The ball guider 272 may be provided with a ball guiding portion 2721, and the ball guiding portion 2721 is able to pass through the second mounting plate member 24. For example, the ball guiding portion 2721 may be a ball bearing, which may be interference-connected to the second mounting plate member 24 to prevent the ball guiding portion 2721 from falling off during the movement of the guide rod 271. The present disclosure does not limit the form and connection manner of the ball guiding portion 2721, and other form and connection manner may also be adopted, which falls within the protection scope of the present disclosure.

In order to further prevent the ball guiding portion from falling off, the ball guiding portion may also be provided with a fourth blocking portion 2722.
