Abstract

The invention provides a silicon wafer cleaning device and a control method thereof. The silicon wafer cleaning device comprises a containing groove, a bearing seat which is located on a bottom wall in the containing groove and used for abutting against a silicon wafer so as to bear the silicon wafer, a first water outlet spray head which is located on one side of an opening of the containing groove and faces the silicon wafer, and a lifting assembly, wherein the lifting assembly is connected with the bottom of the containing groove, the lifting assembly comprises a first lifting mechanism located at a first end and a second lifting mechanism located at a second end, the first end and the second end are two opposite ends of the containing groove, and the first lifting mechanism and the second lifting mechanism are used for lifting so as to adjust an inclination angle of the silicon wafer in the containing groove. The silicon wafer cleaning device is advantaged in that the silicon wafercleaning effect can be improved.

Description

technical field [0001] The invention relates to the technical field of silicon wafer processing, in particular to a silicon wafer cleaning device and a control method thereof. Background technique [0002] Single crystal silicon wafers are used as the substrate material of chips. The particles and metals on the surface of silicon wafers have a great impact on the yield of chips. Therefore, it is necessary to use a large amount of pure water to clean the particles on the surface of silicon wafers during the processing of silicon wafers. with metal. [0003] In the related art, the facing angle between the silicon wafer and the water outlet is small during the cleaning process of the silicon wafer, which leads to the problem of poor flushing effect. Contents of the invention [0004] Embodiments of the present invention provide a silicon wafer cleaning device and a control method thereof, so as to solve the problem of poor flushing effect caused by a small direct angle betw...
