Description

Technical Field

[0002] Wafer refers to the silicon wafer used to make silicon semiconductor circuits. Its raw material is silicon. High-purity polycrystalline silicon dissolves and infiltrates into silicon crystal seeds, and then slowly pulls out to form cylindrical single crystal silicon. After grinding, polishing, and slicing, the silicon crystal rod forms a silicon wafer, also known as a wafer.

[0003] The main processing methods for wafers are piece processing and batch processing, that is, processing one or more wafers at the same time. As the feature size of semiconductors becomes smaller and smaller, and the processing and measurement equipment becomes more and more advanced, new data characteristics have emerged in wafer processing. At the same time, the reduction in feature size has increased the impact of the number of particles in the air in the wafer processing room on the quality reliability of wafer processing.

[0004] Wafer processing also requires cleaning and coating processes to ensure the quality of the wafer after processing. As the characteristic size of wafers is getting smaller and smaller, wafers are generally processed in batches in subsequent processing operations to improve work efficiency. Semiconductor fixtures are needed for subsequent wafer processing. Most of the semiconductor fixtures currently on the market cannot uniformly process batches of wafers, resulting in low production efficiency. Utility Model Content

[0034] refer to Figures 1 to 4 A semiconductor clamp according to a preferred embodiment of the utility model will be described in detail below. The semiconductor clamp includes a carrier plate 10 and a clamping unit 20. The carrier plate 10 is provided with a plurality of mounting grooves 11. The semiconductor is placed in the mounting grooves 11. The clamping unit 20 is installed in the mounting grooves 11 for fixing the semiconductor installed in the mounting grooves 11.

[0035] Specifically, the cross-sectional shape of the mounting groove 11 is an inverted trapezoid, that is, the diameter of the mounting groove 11 gradually decreases from top to bottom. This arrangement can adapt to semiconductor wafers of more specifications. It is worth mentioning that the depth of the mounting groove 11 is less than the thickness of the wafer, which is convenient for subsequent cleaning and lamination.

[0036] Specifically, the clamping unit 20 includes a suction component 21 , and the suction component 21 is installed in the mounting groove 11 , that is, the suction component 21 generates suction to adsorb and fix the wafer placed in the mounting groove 11 .

[0037] Preferably, the suction assembly 21 includes a support plate 211, a plurality of suction holes 212, and an air pump 213, wherein the support plate 211 is mounted on the mounting slot 11, the support plate 211 is arranged in parallel, and is used to support the wafer; the suction holes 212 are opened on the support plate 211, and the air pump 213 is connected to the suction holes 212. In this way, when the air pump 213 is working, the air pump 213 generates suction, so that the wafer placed on the support plate 211 can be stably adsorbed on the support plate 211.

[0038] Specifically, the semiconductor fixture includes an elastic member 30, and the elastic member 30 is installed in the mounting groove 11. It is worth mentioning that the elastic member 30 includes a rubber pad 31, and the rubber pad 31 is adapted to the mounting groove 11. It is worth mentioning that the side of the rubber pad 31 connected to the support plate 211 is set in a grid shape.

[0039] That is, when the vacuum pump 213 is working, suction is generated to adsorb the wafer to the side close to the support plate 211, and the wafer is pressed against the rubber pad 31. After the rubber pad 31 is deformed, the wafer is more stably fixed on the support plate 211.

[0040] It is worth mentioning that the elastic member 30 also includes a metal frame 32, the shape of the metal frame 32 is the same as the grid shape of the rubber pad 31, and is used to support the grid shape of the rubber pad 31 to prevent the grid-shaped part of the rubber pad 31 from breaking and damaging due to continuous backlog during use.

[0041] Specifically, the metal skeleton 32 includes a plurality of metal bars, which are arranged in a predetermined order to form a plurality of quadrilaterals. In this way, the grid shape of the rubber pad 31 will not affect the wind force generated by the suction hole 212 , and the metal skeleton 32 can increase the service life of the rubber pad 31 .

[0042] Preferably, the rubber pad 31 includes a lap 33, the lap 33 is annular and connected to the side of the rubber pad 31 away from the grid shape, and the lap 33 is connected to the upper surface of the carrier plate 10.

[0043] Specifically, the suction assembly 21 also includes a blower 214, which is installed in the suction hole 212. In the present embodiment, the blower 214 and the vacuum pump 213 work at opposite working hours. The blower 214 can generate wind force on the suction hole 212, and can push the wafer installed in the mounting groove 11 out of the mounting groove 11, so as to facilitate the operator to disassemble.

[0044] Specifically, a label plate 40 is provided on the carrier tray 10 , and the label plate 40 is installed on the side wall of the carrier tray 10 , so that an operator can know the specifications of the semiconductor chips on the carrier tray 10 through the label plate 40 .

[0045] In summary, the operator places the wafers to be cleaned or coated in the mounting groove 11 of the carrier plate 10 in accordance with the specifications, and turns on the vacuum pump 213, so that the wafers are stably fixed in the mounting groove 11, and the upper surface of the wafer protrudes from the carrier plate 10, and the cleaning or coating work can be performed. When the wafer is cleaned or coated, the vacuum pump 213 stops working, and the blower 214 is turned on at this time, so that the wafer can be easily taken out of the mounting groove 11.
