[0002] The wafer in the prior art refers to the substrate (also called base) for manufacturing semiconductor transistors or integrated circuits. It is called a wafer because it is made of crystalline material and is round in shape. The wafer suction plate is used to vacuum-absorb the wafer and fix it on the suction plate during the semiconductor manufacturing process, and perform photolithography and glue coating operations on the wafer.

[0003] The Chinese patent with publication number CN211788958U discloses a semiconductor wafer suction cup, which solves the technical problem that the current suction cup can only handle wafers of a single size. It includes a suction cup body, a connecting sleeve with an internal thread, and a connecting piece with an external thread. The connecting sleeve and the suction cup body are detachably connected, and the connecting piece passes through the connecting sleeve and is threadedly connected to the suction cup body, so that the suction cup body and the connecting sleeve are detachably fixed together. According to the above technical scheme, the wafer suction cup structure with suction cup bodies of different sizes can be replaced, so that after the suction cup is equipped, the purpose of handling multiple sizes of wafers can be achieved by disassembling the suction cup body.

[0004] The above semiconductor wafer suction cup needs to replace the suction cup body when sucking and picking up semiconductor wafers of different sizes, and needs to be stopped for replacement. It is inconvenient to replace and also increases the operation time, reducing the suction efficiency of the wafer.

[0005] In view of this, the present utility model is proposed. Utility Model Content
