Description

Technical Field

[0001] This utility model relates to the field of wafer processing technology, specifically to a film application device with an automatic flipping function. Background Technology

[0002] In the field of semiconductor chip manufacturing, wafers are the core basic material, and the precision and efficiency of their processing technology directly determine the performance and yield of the chips. During the manufacturing, processing, and transportation of wafers, in order to prevent physical damage, chemical contamination, and electrostatic interference to the surface, it is usually necessary to apply a protective film to the front side and polish the back side.

[0003] For example, patent CN222320202U discloses a wafer lamination device, including a stage, a lamination assembly, and a cutting assembly. The lamination assembly includes lamination rollers and a drive mechanism for driving the lamination rollers. The drive mechanism includes a rotary motor, a drive pulley, an intermediate pulley, a drive rod, a synchronous pulley, and a driven pulley. Connecting blocks are provided between the two ends of the lamination rollers and the second synchronous belt, and the lamination rollers are elastically connected to the connecting blocks. The cutting assembly includes a rotary cutting mechanism and a linear cutting mechanism that are elastically arranged. In this utility model, the rotary motor drives the connecting blocks on both sides to move synchronously through the drive pulley, the first synchronous pulley, the intermediate pulley, the drive rod, the synchronous pulley, and the second synchronous belt in sequence, thereby driving the lamination rollers between the two connecting blocks to reciprocate so that the protective film is laminated to the wafer to complete the lamination process.

[0004] However, the above technology does not flip the wafer after applying the film to the front side, which leads to the following problem: after applying the film to the front side of the wafer, the back side needs to be polished. However, the existing technology involves manual flipping, which is not only inefficient but also difficult to meet the needs of large-scale production.

[0005] Based on this, the present invention designs a film-applying device with an automatic flipping function to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] In some embodiments, please refer to the accompanying drawings. Figures 1-7A film applicator with an automatic flipping function includes a main body 1, an applicator 2, and a flipping and feeding assembly 3. The main body 1 is connected to the applicator 2, and the flipping and feeding assembly 3 is located on the left side of the main body 1.

[0032] The film-applying mechanism 2 includes a film-pressing assembly 21 with elastic adaptive function, a film-cutting module 22 adapted to different sizes, a film-separating module 23 for separating the film sheet from the master roll after film application, and a feeding module 24. The film-pressing assembly 21, the film-cutting module 22, the film-separating module 23, and the feeding module 24 are all installed on the main body 1 of the equipment.

[0033] This utility model achieves full automation of wafer lamination and unloading through the cooperation of the main body 1, the film lamination mechanism 2, and the flipping and unloading assembly 3. The film lamination assembly 21, the film cutting module 22, the film separating module 23, and the feeding module 24 work together to accurately complete the film conveying, lamination, cutting, and separation. The flipping and unloading assembly 3 uses the cam groove 34 to flip the wafer so that the film-laden side faces down, directly providing an operating reference surface for subsequent defect detection of the unlaminated side, such as optical inspection, electronic inspection, and processing processes such as etching, deposition, and grinding. This avoids contamination and damage caused by manual contact, while meeting the strict requirements of cleanrooms for dust-free operation and improving the automation level and process reliability of semiconductor manufacturing.

[0034] Meanwhile, the feeding module 24 and the flipping unloading component 3 enable rapid unloading. The overall equipment is efficient, precise, and intelligent, which can effectively improve the quality and efficiency of wafer production.

[0035] The main body of the equipment 1 includes a workbench 11, a double slider belt module 12, and a placement plate 15; the right side of the workbench 11 is fixedly connected to the double slider belt module 12, the left side of the workbench 11 is provided with a sliding groove 13, the middle part of the workbench 11 is provided with a slot 14, and the placement plate 15 is slidably connected to the slot 14.

[0036] The two output ends of the dual slider belt module 12 are connected to the film pressing assembly 21 and the film separating module 23 respectively. The slide 13 is connected to both the film pressing assembly 21 and the film separating module 23. The worktable 11 is connected to the film cutting module 22. The lower end of the placement plate 15 is connected to the feeding module 24.

[0037] The dual-slider belt module 12 adopts an existing mature structure and is a linear motion module based on synchronous belt drive. It drives two sliders (slide tables) through two synchronous belts to achieve independent linear motion in two stations.

[0038] like Figure 3 and Figure 4As shown, the pressing assembly 21 includes a first slider 211, a pressure roller 212, and a spring 213. There are two first sliders 211, which are located on the left and right sides of the worktable 11 respectively. One output end of the double slider belt module 12 is fixedly connected to one first slider 211, and the other first slider 211 is slidably connected to the slide groove 13. The upper inside of each of the two first sliders 211 is fixedly installed with a spring 213. The two ends of the pressure roller 212 are slidably connected to the inside of the two first sliders 211 respectively, and the lower ends of the two springs 213 are fixedly connected to the two ends of the pressure roller 212 respectively.

[0039] Effect: The external feeding assembly places the wafer on the upper end of the placement plate 15, and the external unwinding assembly passes the film through the fixing rod 232 and the pressure block 233, through the lower end of the pressure roller 212, and then unwinds it to the upper end of the placement plate 15.

[0040] Then cylinder 234 is started, cylinder 234 drives pressure block 233 to move downward, pressure block 233 drives the diaphragm to fit against the fixing rod 232, thereby fixing the diaphragm roll.

[0041] When one output end of the dual slider belt module 12 is activated, the dual slider belt module 12 drives the first slider 211 to move. The first slider 211 drives the pressure roller 212 to move and contact the diaphragm. Under the action of the spring 213, the pressure roller 212 puts the diaphragm into contact with the front side of the wafer.

[0042] The pressure roller 212, through the action of the spring 213, can evenly and tightly press the film onto the front side of the wafer, ensuring that there are no bubbles or wrinkles during the film application process, and significantly improving the film application quality and yield.

[0043] like Figures 3-5 As shown, the film cutting module 22 includes a fixed frame 221, a cylinder 222, a rotary actuator 223, a crossbar 224, and a blade 226. The left and right ends of the fixed frame 221 are fixedly connected to the left and right sides of the worktable 11, respectively. The upper end of the fixed frame 221 is fixedly connected to the cylinder 222. The output end of the cylinder 222 is fixedly connected to the rotary actuator 223. The output end of the rotary actuator 223 is fixedly connected to one end of the crossbar 224. A sliding groove 225 is provided in the middle of the crossbar 224. The sliding groove 225 is detachably connected to the upper end of the blade 226.

[0044] The rotary actuator 223 employs existing mature technologies, such as the Festo DRQD series of electrically driven rotary modules.

[0045] The blade 226 is detachably connected to the sliding groove 225 by bolts, allowing the blade 226 to be adjusted and fixed inside the sliding groove 225. The position of the blade 226 can be adjusted according to the radius of the wafer, realizing the function of adapting to wafers of different sizes, being compatible with products of different specifications, and improving the versatility of the equipment. The detachable design of the blade 226 supports quick replacement of worn tools, shortening equipment maintenance time.

[0046] Effect: After the diaphragm is attached to the front side of the wafer, cylinder 222 is activated, driving rotary actuator 223 to move downwards until the blade 226 contacts the diaphragm. Rotary actuator 223 then drives crossbar 224 to rotate, which in turn drives blade 226 to perform a 360-degree circular motion. This drives blade 226 to complete a circular cut along the edge of the wafer, thereby separating the diaphragm from the entire diaphragm roll. This ensures that the cutting trajectory accurately matches the wafer contour, avoiding the uneven edge problem caused by traditional straight-line cutting.

[0047] like Figure 5 As shown, the film-separating module 23 includes a second slider 231, a fixing rod 232, a pressure block 233, a second cylinder 234, and a connecting plate 235. Two of each of the second slider 231, pressure block 233, and second cylinder 234 are provided and located on the left and right sides of the worktable 11, respectively. The other output end of the double slider belt module 12 is fixedly connected to one of the second sliders 231, and the other second slider 231 is slidably connected to the slide groove 13. The left and right ends of the fixing rod 232 are fixedly connected to the inner sides of the two second sliders 231, and the left and right sides of the connecting plate 235 are fixedly connected to the two second sliders 231, respectively. The second cylinder 234 is fixedly installed on the upper end of the connecting plate 235, and the output end of the second cylinder 234 is fixedly connected to the pressure block 233.

[0048] Effect: After the wafer is coated, cylinder 234 is reset and drives the pressure block 233 to move upward, so that the pressure block 233 separates from the film.

[0049] The other output end of the dual slider belt module 12 is activated, driving the second slider 231 to move. The second slider 231 drives the fixed rod 232 and the pressure block 233 to move, so that the entire film roll is separated from the wafer, completing the material distribution and realizing the rapid separation of the film roll from the wafer after film application, reducing manual intervention.

[0050] The feeding module 24 includes a linear module slide 241 and a cylinder 242. The linear module slide 241 is fixedly installed at the lower end of the workbench 11, and the cylinder 242 is fixedly installed on the output end of the linear module slide 241. The output end of the cylinder 242 is fixedly connected to the lower end of the placement plate 15.

[0051] Effect: After the wafer is coated, cylinder 3 242 drives the placement plate 15 to move downwards, and linear module slide 1 241 drives cylinder 3 242 to move to the unloading position;

[0052] The linear module slide 241 is linked with the cylinder 242 to drive the placement plate 15 to quickly move the wafer after film application to the unloading position, shortening the loading and unloading cycle and improving production efficiency.

[0053] like Figure 6 and Figure 7 As shown, the flipping and unloading assembly 3 includes a linear module slide 2 31, a vertical rod 32, a mounting plate 33, a linear module slide 35, a flipping frame 36, a vacuum suction cup 37, a detection workbench 38, sliding wheels 39, a connecting block 310, and a fixing block 311. The output end of the linear module slide 2 31 is fixedly connected to one end of the mounting plate 33, and the vertical rod 32 is slidably connected to the other end of the mounting plate 33. The mounting plate 33 has a cam groove 34. The end of the linear module slide 35 is fixedly connected to the output end of the linear module slide 35 and is rotatably connected to the fixed block 311. One end of the connecting block 310 is fixedly connected to the fixed block 311, and the other end of the connecting block 310 is rotatably connected to the sliding wheel 39. The sliding wheel 39 is rotatably connected to the cam groove 34. The fixed block 311 is fixedly connected to the flipping frame 36. The lower end of the flipping frame 36 is fixedly connected to multiple vacuum suction cups 37. The detection workbench 38 is located at the front left end of the mounting plate 33.

[0054] The flipping frame 36 is composed of a grid-like frame structure made of multiple parallel long bars with a certain spacing between the bars;

[0055] The testing workbench 38 is also a frame structure composed of multiple parallel long rods, with supporting legs, and is table-shaped. The arrangement of the rods of the testing workbench 38 forms a space through which the flipping frame 36 can pass.

[0056] The cam groove 34 includes horizontal portions on both sides and a recessed portion in the middle. The horizontal portions and the recessed portion are smoothly connected. The cam groove 34 constrains the movement trajectory of the sliding wheel 39 through the geometry of the horizontal portions and the recessed portion, so that when the sliding wheel 39 passes through the recessed portion in the middle, it will drive the fixed block 311 to rotate 180 degrees.

[0057] The outer end of the sliding wheel 39 is fixedly installed with a bearing shaft, which can effectively support the sliding wheel 39, reduce the friction and wear generated when the sliding wheel 39 slides in the cam groove 34, and extend the service life of the sliding wheel 39.

[0058] Effect: The vacuum chuck 37 adsorbs the front film-coated side of the wafer. Then, the linear module slide 2 31 is activated. The output end of the linear module slide 2 31 drives the mounting plate 33 to move upward. Then, the linear module slide 35 is activated. The output end of the linear module slide 35 drives the fixed block 311 to move. The fixed block 311 moves the connecting block 310. The connecting block 310 drives the sliding wheel 39 to slide in the cam groove 34. Due to the special shape of the cam groove 34, the sliding wheel 39 moves horizontally while driving the fixed block 311 to rotate 180 degrees. This causes the flipping frame 36 to drive the vacuum chuck 37 to flip 180 degrees. The vacuum chuck 37 drives the wafer to flip 180 degrees, so that the reverse side of the wafer is facing upward. At this time, the linear module slide 2 31 is activated and the mounting plate 33 moves downward. The mounting plate 33 drives the wafer to move downward and places the wafer on the upper end of the inspection workbench 38, completing the wafer unloading.

[0059] This utility model enables automated wafer unloading, and during the unloading process, the wafer is flipped so that the film-coated side is facing down and the reverse side is facing up. This not only avoids dust adhering to the reverse side during unloading, but more importantly, it provides a direct operating surface for wafer reverse side defect detection and subsequent processing, eliminating the need for manual flipping, reducing the risk of contamination and scratches, meeting the requirements for fine processing of both sides in semiconductor processes, and improving the level of automation and production efficiency of the entire process.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
