Description

Technical Field

[0001] The present invention relates to the technical field of centrifugal layer expansion containers, and particularly to a centrifugal layer expansion container for a frame bonding and glue tearing machine. Background Art

[0002] A frame bonding and glue tearing machine ionizes oxygen or other reaction gases by using microwave plasma to form chemically active free radicals, which then react with the photoresist to generate volatile substances that are evacuated from the cavity by a vacuum pump, thereby achieving the functions of photoresist etching and removal. A wafer refers to a silicon wafer used for fabricating silicon semiconductor integrated circuits. Since its shape is circular, it is called a wafer; various circuit element structures can be fabricated on the silicon wafer to form an integrated circuit product with specific electrical functions. A wafer manufacturing factory melts this polysilicon, then seeds a seed crystal in the melt, and then slowly pulls it out to form a cylindrical single crystal silicon ingot. Since the silicon ingot is gradually formed from a seed crystal with a determined crystal plane orientation in the molten silicon raw material. The silicon ingot is then cut into segments, ground, sliced, chamfered, polished, laser engraved, and packaged to become the basic raw material of an integrated circuit factory - a silicon wafer, which is the "wafer". A centrifugal layer expansion container is a device used for coating a resist on the surface of a wafer.

[0003] In the prior art, during the use of a centrifugal layer expansion container, it is not convenient to position the wafer and not convenient to quickly and evenly dry the resist, which leads to a reduction in the production efficiency of silicon wafers. For this reason, we propose a centrifugal layer expansion container for a frame bonding and glue tearing machine to solve the above problems. Summary of the Invention

The outer side of the third rotating shaft 28 is slidably connected to the inner wall of the fifth through hole. One end of the third rotating shaft 28 is fixedly installed with a gear 29 by welding. The gear 29 meshes with the rack 26. When the rack 26 moves vertically, the rack 26 can drive the gear 29 to rotate.

[0032] In this embodiment, a third sliding slot is formed in the top inner wall of the fourth empty slot. The third sliding slot communicates with the third empty slot 27.

The top of the rectangular rod 25 is fixedly connected to one end of the rack 26 by welding. A waist-shaped slot is formed on the outer side of the rectangular rod 25. Through the setting that the outer side of the connecting column 24 is slidably connected to the inner wall of the waist-shaped slot, when the connecting column 24 makes a circular motion, the connecting column 24 can drive the rectangular rod 25 to move vertically in a reciprocating manner.

[0033] In this embodiment, a fourth through hole is formed in one inner wall of the second empty slot 18. The fourth through hole communicates with the fourth empty slot.

[0034] Working principle: When in use, the wafer can be placed on the top of the disc 6, and then the handwheel 15 is rotated. The handwheel 15 drives the first rotating shaft 14 to rotate. The first rotating shaft 14 drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the second bevel gear 17 to rotate. The second bevel gear 17 drives the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives two first sliders 8 to approach each other. The two first sliders 8 respectively drive two fixing blocks 9 to approach each other. The two fixing blocks 9 respectively drive two second sliders 10 and two arc-shaped clamping plates 11 to approach each other. Thus, the two arc-shaped clamping plates 11 can clamp and position the wafer. Then, the resist is applied to the surface of the wafer. The motor 19 and the blower 34 are turned on. The motor 19 drives the worm 20 to rotate. The worm 20 drives the connecting plate 5 to rotate. The connecting plate 5 drives the disc 6 to rotate. The disc 6 drives the wafer to rotate. Thus, the resist on the surface of the wafer can be evenly coated by the rotational centrifugal force. At the same time, the blower 34 generates wind pressure. Turning on multiple electric heating rods 33 can generate heat. The wind pressure generated by the blower 34 can discharge the heat generated by the multiple electric heating rods 33 through the corrugated pipe 31 and the air outlet 30. Thus, the discharged heat can quickly dry the applied resist. At the same time, the worm 20 drives the worm wheel 22 to rotate. The worm wheel 22 drives the second rotating shaft 21 to rotate. The second rotating shaft 21 drives the turntable 23 to rotate. The turntable 23 drives the connecting column 24 to perform a circular motion. Through the setting that the outer side of the connecting column 24 is slidably connected to the inner wall of the waist-shaped groove, the connecting column 24 can drive the rectangular rod 25 to move vertically in a reciprocating manner. The rectangular rod 25 drives the toothed rod 26 to move vertically in a reciprocating manner. The toothed rod 26 drives the gear 29 to reciprocate and rotate forward and backward. The gear 29 drives the third rotating shaft 28 and the air outlet 30 to reciprocate and rotate forward and backward. Thus, the air outlet 30 can evenly discharge the heat, thereby evenly and quickly drying the applied resist layer and improving the production efficiency of the silicon wafer.

[0035] Embodiment 2

[0036] The difference from the first embodiment is as follows: A cover plate 2 is hinged to the outer side of the housing 1. A drying box 3 is fixedly installed at the top of the housing 1 by welding. A support 4 is fixedly installed at the bottom inner wall of the housing 1 by welding. A rotating groove is formed at the top of the support 4. A connecting plate 5 is rotatably installed in the rotating groove. A disc 6 is fixedly installed at the top of the connecting plate 5 by welding. An annular groove is formed in the inner wall of the rotating groove. Two guiding blocks 36 are slidably installed in the annular groove. The outer sides of the two guiding blocks 36 are fixedly connected to the outer side of the connecting plate 5. Two symmetric first sliding grooves 7 are formed in the disc 6. First sliders 8 are slidably installed in the two first sliding grooves 7. A positioning mechanism is arranged on the two first sliders 8. A first empty groove is formed in the disc 6. A second empty groove 18 is formed in the support 4. An installation hole is formed in the bottom inner wall of the drying box 3. A corrugated pipe 31 is fixedly installed in the installation hole. One end of the corrugated pipe 31 is fixedly communicated with an air outlet 30. An air inlet is formed in the top of the drying box 3. A dust-proof plate 35 is fixedly installed in the air inlet by bolts. A third empty groove 27 and a fourth empty groove are formed in the housing 1. A motor 19 is fixedly installed at the bottom inner wall of the second empty groove 18 by welding. A third through hole is formed in the bottom inner wall of the rotating groove. The third through hole communicates with the second empty groove 18. A worm 20 is rotatably installed in the third through hole. The two ends of the worm 20 are fixedly connected to the output shaft of the motor 19 and the bottom of the connecting plate 5 by welding respectively. When the motor 19 is turned on, the worm 20 can drive the connecting plate 5 to rotate.

[0037] Working principle: When in use, the wafer can be placed on the top of the disc 6, and then the handwheel 15 is rotated. The handwheel 15 drives the first rotating shaft 14 to rotate. The first rotating shaft 14 drives the first bevel gear 16 to rotate. The first bevel gear 16 drives the second bevel gear 17 to rotate. The second bevel gear 17 drives the bidirectional lead screw 13 to rotate. The bidirectional lead screw 13 drives two first sliders 8 to approach each other. The two first sliders 8 respectively drive two fixing blocks 9 to approach each other. The two fixing blocks 9 respectively drive two second sliders 10 and two arc-shaped clamping plates 11 to approach each other. Thus, the two arc-shaped clamping plates 11 can clamp and position the wafer. Then, the resist is applied to the surface of the wafer. The motor 19 and the blower 34 are turned on. The motor 19 drives the worm 20 to rotate. The worm 20 drives the connecting plate 5 to rotate. The two guide blocks 36 can play a role in stabilizing the rotation of the connecting plate 5. The connecting plate 5 drives the disc 6 to rotate. The disc 6 drives the wafer to rotate. Thus, the resist on the surface of the wafer can be evenly coated by the rotational centrifugal force. At the same time, the blower 34 generates air pressure. Turning on multiple electric heating rods 33 can generate heat. The air pressure generated by the blower 34 can discharge the heat generated by the multiple electric heating rods 33 through the corrugated pipe 31 and the air outlet 30. Thus, the discharged heat can quickly dry the coated resist. At the same time, the worm 20 drives the worm wheel 22 to rotate. The worm wheel 22 drives the second rotating shaft 21 to rotate. The second rotating shaft 21 drives the turntable 23 to rotate. The turntable 23 drives the connecting column 24 to move in a circular motion. Through the setting that the outer side of the connecting column 24 is slidably connected to the inner wall of the waist-shaped groove, the connecting column 24 can drive the rectangular rod 25 to move vertically in a reciprocating manner. The rectangular rod 25 drives the toothed rod 26 to move vertically in a reciprocating manner. The toothed rod 26 drives the gear 29 to rotate forward and backward reciprocally. The gear 29 drives the third rotating shaft 28 and the air outlet 30 to rotate forward and backward reciprocally. Thus, the air outlet 30 can evenly discharge the heat, so that the coated resist layer can be evenly and quickly dried, improving the production efficiency of the silicon wafer.
