[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0013] like Figure 1 , 2 As shown, in this embodiment, a device for reducing the fragmentation rate of manually taking out wafers after metallization comprises a base 1, and base grooves 2 are symmetrically provided at the bottom of the inner cavity of the base 1, and the spacing between the two base grooves 2 corresponds to the size of the wafer rack, so that the wafer rack 4 is arranged in the two base grooves 2. A buffer arranged along the width direction of the base is provided at the bottom of the inner cavity of the base 1, and the buffer is provided between the two base grooves 2, and the buffer exceeds the bottom of the wafer rack 4. During the wafer taking operation, the wafer rack 4 is placed in the base groove 2, and the wafer 5 is placed in the wafer rack 4, and the bottom of the wafer 5 contacts the buffer, thereby avoiding hard contact between the wafer and the wafer rack and reducing the wafer fragmentation rate.

[0015] The length of the buffer member matches the width of the base.
[0016] The base of the present application has two base grooves matching the wafer rack, ensuring that the wafer rack can be placed in the base stably and without falling over. A hollow hose with a length consistent with the width of the base is fixed in the base. The taken-out wafer is placed in the wafer rack, and the bottom of the wafer contacts the hollow hose, which solves the problem of hard contact between the wafer and the wafer rack. The present application has a simple and ingenious structure, reduces the wafer fragmentation rate, and reduces cost losses.
