Title: Polishing method for semiconductor wafer
Inventor: YUGAWA ISAO
IPC: H01L21/304
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To restrain movement between a protective member and a wafer, and prevent cracks on a wafer at the time of polishing, by making it an addi tional requisit that a heating and/or an ultraviolet ray irradiation processes are interposed after a coating process of liquid resin. SOLUTION: Liquid resin is spread to have a specified thickness on the surface side, for preventing a circuit 2 of the surface side before the back of a semiconductor wafer 1 is polished. In this case, heat or ultraviolet ray is applied from the surface side of the coated liquid resin, the curing of resin is promoted, and a protective member 3 having a specified hardness and rigidity can be adhered in a comparatively short time. When polishing is performed after the protective member 3 is formed, gaps of unevennesses of the surface side are absorbed. Since the protective member 3 having specified rigidity is collectively constituted, stress is absorbed in the protective member 3 even if the wafer 1 itself has a protrusion 4 such as a bump or a blow mark. The stress does not concentrate on the protrusion 4, so that cracking and breakdown can be prevented.
