Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce rounding at the outer peripheral part of a wafer, increase flatness and shorten a polishing time, by warping and etching a semiconductor wafer, and grinding the surface of the wafer. SOLUTION: A silicon wafer subjected to beveling work is wrapt in a warping process (S103). The silicon wafer subjected to finish beveling is etched (S105). Thereby defects which have been generated on the surface of the wafer are eliminated. Grinding with less damage is performed on the surface of the wafer after etching, by using a resinoid bond grindstone (S105). After that, this ground surface of high flatness is polished (S111). Thereby a semiconductor wafer of high quality in which rounding in the outer peripheral part of the wafer are small is manufactured. Since the surface of the wafer is ground before polishing, a polishing time is shortened.
