Description

Technical Field

[0001] This invention relates to the field of wafer cleaning technology, and more particularly to a horizontal centralized wafer cleaning device. Background Technology

[0002] A wafer is a circular piece of high-purity silicon material used to manufacture silicon semiconductor circuits. The manufacturing process begins with polycrystalline silicon raw material, which is purified, dissolved, and doped with silicon seed crystals. This is then slowly stretched into a cylindrical single-crystal silicon rod. Next, this silicon rod undergoes meticulous grinding, polishing, and slicing processes to finally obtain the wafer we know today. Currently, the mainstream wafer sizes in China are 8 inches and 12 inches. In the later stages of wafer fabrication, removing the adhesive and impurities from the wafer surface is a crucial step, preparing it for subsequent dicing and processing.

[0003] Existing wafer cleaning methods typically require robotic arms to repeatedly grip the wafer and place it into different cleaning tanks for cleaning. This reduces work efficiency, is time-consuming and labor-intensive, and repeated gripping can easily cause irreversible damage to the wafer. It also significantly delays cleaning time and reduces cleaning efficiency. Furthermore, existing wafer cleaning methods leave cleaning solution residues, resulting in insufficient cleaning effectiveness. Summary of the Invention

[0031] The rinsing mechanism includes multiple nozzles 26 arranged horizontally inside the swing chamber 21. Multiple nozzles 27 are arranged on the lower sidewall of each nozzle 26. One end of each nozzle 26 is rotatably connected to the inner wall of the swing chamber 21, and the other end of each nozzle 26 penetrates the inner wall of the swing chamber 21 and extends to the outside of the mounting plate 8. An air tank 10 is located at the upper end of the base 1, and an air valve 11 is connected to the air tank 10. An air supply pipe 9 is connected to the output end of the air valve 11.

[0032] The drive mechanism includes a motor 31 mounted on the inner wall of the device slot 28. The output shaft of the motor 31 is fixedly connected to a first rotating shaft 30. The end of the first rotating shaft 30 away from the motor 31 is rotatably connected to the inner wall of the device slot 28. A turntable 29 is fixedly sleeved on the first rotating shaft 30. Multiple pressing protrusions 47 are fixed on the side wall of the turntable 29 near the second rack 24. The multiple pressing protrusions 47 are evenly distributed along the circumference of the side wall of the turntable 29. When the pressing protrusions 47 press against the second rack 24, the second rack 24 can move. When the pressing protrusions 47 separate from the second rack 24, the elastic force of the second spring 23 can act on the second rack 24, causing the second rack 24 to reset and move.

[0033] The linkage mechanism includes a second rotating shaft 37 rotatably connected to the inner wall of the second device cavity 35. The second rotating shaft 37 passes through the inner wall of the second device cavity 35 and extends to the outside of the side plate 34. A third gear 38 is fixedly connected to one end of the second rotating shaft 37 outside the side plate 34. A second sprocket 36 is fixedly sleeved on the side wall of the second rotating shaft 37 inside the second device cavity 35. A first sprocket 32 ​​is fixedly sleeved on the first rotating shaft 30. The first sprocket 32 ​​and the second sprocket 36 are connected by a transmission chain 33.

[0034] The loading mechanism includes a placement rack 42, with multiple placement slots 43 arranged at the upper end of the placement rack 42. Ball bearings are embedded in the inner walls of the placement slots 43 for positioning the wafer body 46. Each placement slot 43 contains a wafer body 46. Connecting blocks 44 are fixedly connected to the left and right side walls of the placement rack 42. Connecting seats 45 are fixedly connected to the side walls of the two side plates 34. The connecting blocks 44 are rectangular blocks, and the connecting seats 45 have rectangular slots that mate with the connecting blocks 44. The two connecting blocks 44 are located on two connecting... Inside the receiving base 45, a third rotating shaft 40 is provided through the interior of the placement rack 42. One end of the third rotating shaft 40 is rotatably connected to the interior of the placement rack 42, and the other end of the third rotating shaft 40 extends out of the placement rack 42 and is fixedly connected to a third gear 38 and a fourth gear 39. The fourth gear 39 meshes with the third gear 38. Multiple friction rollers 41 are fixedly sleeved on the side wall of the third rotating shaft 40. The multiple friction rollers 41 extend into the interior of multiple placement slots 43, and the friction rollers 41 are in contact with the bottom of the wafer body 46.

[0035] The inner wall of the first device cavity 18 is provided with a limiting groove 15. The end of the first rack 17 away from the traction rope 5 is slidably inserted into the interior of the limiting groove 15. The base 1 is equipped with a reversing wheel 20, and the traction rope 5 is wound around the reversing wheel 20.

[0036] When using this invention, the wafer body 46 is placed inside the placement slot 43, then the placement rack 42 is placed between the two side plates 34, and then the connecting block 44 is inserted into the connecting seat 45 to complete the loading of the wafer body 46. At this time, the third gear 38 and the fourth gear 39 mesh.

[0037] Then, the electric telescopic rod 7 is activated to extend, causing the moving plate 6 to move downwards, which in turn causes the mounting plate 8 to move downwards. This allows the placement rack 42 and the wafer body 46 to move into the cleaning box 12. Simultaneously, the nozzle 27 is inserted into the cleaning fluid in the cleaning box 12. The air valve 11 is activated to discharge the high-pressure gas from the air tank 10 and spray it into the cleaning fluid through the nozzle 27. This allows the airflow to carry the cleaning fluid and rinse the wafer body 46. The motor 31 is activated to drive the first rotating shaft 30 to rotate. The first rotating shaft 30 drives the turntable 29 to rotate, which in turn causes the extrusion protrusion 47 to intermittently extrude the second rack 24, causing the second rack 24 to reciprocate. Since the second rack 24 meshes with the second gear 25, it drives the second gear 25 to reciprocate, which in turn drives the nozzle 26 to oscillate back and forth. This, in turn, drives the nozzle 27 to oscillate back and forth, thus preventing impurities from adhering during the cleaning process and effectively cleaning the wafer body 46, improving the cleaning effect.

[0038] When the first rotating shaft 30 rotates, it can drive the first sprocket 32 ​​to rotate. Through the transmission action of the transmission chain 33, it can drive the second sprocket 36 to rotate, which in turn drives the second rotating shaft 37 to rotate. The second rotating shaft 37 drives the third gear 38 to rotate. Since the third gear 38 meshes with the fourth gear 39, it can drive the third rotating shaft 40 to rotate. The third rotating shaft 40 drives the friction roller 41 to rotate. Through the friction force of the friction roller 41 contacting the wafer body 46, it can drive the wafer body 46 inside the placement rack 42 to rotate. Thus, while cleaning the wafer body 46, it drives the wafer body 46 to rotate, which can achieve thorough cleaning of the wafer body 46 and further improve the cleaning effect.

[0039] After cleaning is completed, the electric telescopic rod 7 is retracted, which moves the moving plate 6 upward and moves the wafer body 46 out of the cleaning box 12. During the upward movement of the moving plate 6, the first rack 17 is pulled by the traction rope 5. When the first rack 17 moves, it can drive the first gear 16 to rotate. At this time, the one-way bearing can drive the rotating column 14 to rotate. The rotating column 14 drives the turntable 13 to rotate. The rotation of the turntable 13 drives the cleaning box 12 to rotate. Thus, the position of the cleaning box 12 can be automatically changed after each cleaning of the wafer body 46.

[0040] Repeat the above process to perform the next cleaning of the wafer body 46.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
