Description

Technical field [0001] The present invention relates to the field of wafer cleaning, and in particular, a wafer surface dry purge apparatus. Background technique [0002] The wafer is the most commonly used semiconductor material, and is also a carrier used in the smart chip, as a circle is circular, referred to as a wafer. After the wafer is completed, the wafer is attached to an approximately 2 μm Al. 2 O 3 And the glycerol mixed liquid protection layer (hereinafter referred to as the protective layer), the wafer first needs to be cleaned before making a smart chip. [0003] The wafer production surface cleaning apparatus is a auxiliary device for wafer, a protective layer that is dissolved on a protective layer thereof in the surface, is widely used in wafer production. The general wafer produces a surface cleaning device, and the multi-set wafer is placed directly on the mesh, causing a multi-set wafer to be placed, stacked with each other, and chemical solutions in the proce...

Problems solved by technology

However, the above solution can only clean the surface of a wafer of one specification, and has poor versatility; and after cleaning the surface of the wafer, the wafer needs to be moved to another drying device for drying
