Method of producing semiconductor wafer

Abstract

A method of producing a semiconductor wafer, which can prevent the breakage of a wafer, and also can reduce the working time in a series of operations attended by back surface grinding of the semiconductor wafer. The method involves producing a semiconductor wafer wherein an adhesive tape is applied on the surface of the semiconductor wafer and, after grinding the back surface of the semiconductor wafer using a grinding machine, the adhesive tape is peeled off, said process comprises using an adhesive tape having heat shrinkability as the adhesive tape, grinding the back surface of the semiconductor wafer and heating the adhesive tape in the grinding machine, thereby peeling off the adhesive tape from the surface of the semiconductor wafer.
