WebbAdhesion of semiconductor wafers and supporting glass plates During ultra-thin polishing of wafers, the wafer is bonded to a supporting glass plate with UV-curing liquid adhesive. The adhesive turns into a UV resin layer and comes off together with the glass plate after the process ends. In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer. It undergoes … Visa mer In the semiconductor or silicon wafer industry, the term wafer appeared in the 1950s to describe a thin round slice of semiconductor material, typically germanium or silicon.
