[0002] Wafer manufacturing requires the use of chemical plating or electroplating techniques to meet the performance and manufacturing requirements of advanced semiconductor devices. During chemical or electroplating, wafers must be held in place in the plating solution using racks to prevent displacement or damage due to flow or mechanical vibration. Using racks ensures uniform plating, improves production efficiency, and guarantees process stability.

[0003] Current wafer production methods, such as chemical plating or electroplating, require wafers of different sizes. Different sizes of wafers require different sizes of racks for support, and the development or purchase of different racks is costly.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The front rack and the rear rack have placement slots with the same outline as the through holes on their opposing inner sides. The placement slots are used to place wafers of different sizes. The placement slots are composed of a rectangular slot, an inverted trapezoidal slot, and a semi-circular slot arranged sequentially from top to bottom. The top of the rectangular slot is located inside the top surface of the front rack and the rear rack.

[0008] Furthermore, the through hole is composed of a rectangular hole, an inverted trapezoidal hole, and a semi-circular hole arranged sequentially from top to bottom. The top end of the inverted trapezoidal hole is connected to the rectangular hole, and the bottom end of the inverted trapezoidal hole is connected to the semi-circular hole.

[0009] Furthermore, the size of the placement groove is larger than the size of the through hole.

[0010] Furthermore, the top of the inverted trapezoidal groove is connected to the rectangular groove, and the bottom of the inverted trapezoidal groove is connected to the semi-circular groove.

[0011] Furthermore, the left and right sides of the placement slot are provided with multiple connection holes, which penetrate the main body of the front and rear mounting plates.

[0012] Furthermore, the multiple connecting holes are evenly distributed at equal intervals along the vertical direction.

[0013] Furthermore, a connector is inserted through the connection hole, which fixes the front mounting plate and the rear mounting plate together.

[0014] Furthermore, the top of both the front and rear mounting plates are provided with ear plates integrally formed therewith, and each ear plate is provided with a hanging hole.

[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0016] The front and rear mounting plates are provided with placement slots for placing wafers on their inner sides. The placement slots are composed of rectangular slots, inverted trapezoidal slots and semi-circular slots arranged from top to bottom. They can clamp and fix wafers of different sizes, and facilitate chemical plating or electroplating of wafers of different sizes.

[0024] like Figures 1-3As shown in the figure, this utility model provides a universal rack for wafer production, including a front rack 1 and a rear rack 2 symmetrically arranged. Both the front rack 1 and the rear rack 2 have through holes 5 on their main bodies for the flow of plating solution. The front rack 1 and the rear rack 2 have placement grooves 6 with the same outline as the through holes 5 on their opposing inner sides for placing wafers 8 of different sizes.

[0025] The through hole 5 is composed of a rectangular hole 51, an inverted trapezoidal hole 52 and a semi-circular hole 53 arranged sequentially from top to bottom. The top end of the inverted trapezoidal hole 52 is connected to the rectangular hole 51, and the bottom end of the inverted trapezoidal hole 52 is connected to the semi-circular hole 53.

[0026] The size of the placement slot 6 is larger than the size of the through hole 5.

[0027] The placement groove 6 is composed of a rectangular groove 61, an inverted trapezoidal groove 62 and a semi-circular groove 63 arranged sequentially from top to bottom. The top end of the inverted trapezoidal groove 62 is connected to the rectangular groove 61, and the bottom end of the inverted trapezoidal groove 62 is connected to the semi-circular groove 63.

[0028] The top of the rectangular groove 61 is located inside the top surfaces of the front mounting plate 1 and the rear mounting plate 2, and the wafer 8 is placed into the placement groove 6 from the top of the front mounting plate 1 and the rear mounting plate 2.

[0029] The placement slot 6 has multiple connecting holes 7 on its left and right sides respectively. The connecting holes 7 penetrate the main body of the front hanging plate 1 and the rear hanging plate 2. The multiple connecting holes 7 are evenly distributed at equal intervals along the vertical direction.

[0030] A connector is inserted through the connection hole 7, which fixes the front mounting plate 1 and the rear mounting plate 2 together, so that a clamping and placement space for the wafer 8 is formed between the front mounting plate 1 and the rear mounting plate 2.

[0031] The top of both the front mounting plate 1 and the rear mounting plate 2 is provided with an ear plate 3 integrally formed therewith, and the ear plate 3 is provided with a hanging hole 4. The ear plate 3 and the hanging hole 4 are manufactured according to the requirements of different production lines.
