The application discloses a wafer defect detection device and method, and belongs to the field of semiconductor element detection. The wafer defect detection device comprises a detection substrate, and further comprises a support assembly for fixing a wafer, the support assembly being reversibly mounted on the detection substrate; an air jet assembly for cleaning the surface of the wafer; and a coating assembly for spraying detection material on the surface of the wafer, the coating assembly being movably arranged above the support assembly. The wafer defect detection device can select the number of suction cups according to the size of the wafer, the contact friction between the suction cups and the wafer is small, and the damage to the wafer is reduced as much as possible. The size of the recess defect on the wafer is increased, so that the recess defect can be conveniently detected, the occurrence of the defect can be effectively detected in time, and the loss caused by the defect is reduced. The air pipe is used to remove dust on the surface of the wafer, and the coating of a compound and the timely surface cleaning can be realized.

This application discloses a tire mold, belonging to the field of tire mold technology. The tire mold includes: a base and a tread pattern shell. The base is provided with multiple positioning elements; the tread pattern shell is provided with a positioning groove, and the tread pattern shell is installed on the positioning elements. A flow guiding gap is formed between the tread pattern shell, the positioning elements, and the base. The flow guiding gap includes a first gap. The top surface of the positioning element abuts against the bottom wall of the positioning groove, and a first gap is formed between the tread pattern shell and the mounting surface. The base is provided with a first exhaust channel, and the positioning elements are provided with a second exhaust channel. The first exhaust channel and the second exhaust channel are connected, and the flow guiding gap is connected to the second exhaust channel. The tread pattern shell includes an arc-shaped transition section, which extends from the starting position to the side where the positioning groove is located. The tangent of the arc-shaped transition section at the starting position has an angle α with a preset direction, and the value range of α is: 0°≤α≤60°. This solves the technical problems of inconvenient tread pattern replacement and easy clogging of the exhaust structure in existing tire molds.
