Title: Polishing method of semiconductor wafer and polishing cloth used for this polishing method
Inventor: SUZUKI KIYOSHI
IPC: B24B37/24
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To provide a silicon wafer having excellent surface roughness of the silicon wafer mirror surface by performing finishing polishing by finishing polishing cloth having specific foaming density of a pore of the polishing cloth surface and the compressibility. SOLUTION: Mechanochemical polishing is performed by slidingly rubbing motion between a wafer 12, an abrasive 16 and polishing cloth 14 existing on the under surface in a state of interposing a slurry-like abrasive 16 by a slurry supply pipe 15 between the wafer 12 and the polishing cloth 14 stuck on a base material. In this case, the finishing polishing cloth 14 having foaming density not less than 150 pieces/cm<2> and compressibility less than 9% is desirably used. This is thought because of the action of eliminating application nonuniformity of the wafer 12 and the polishing cloth 14 by reducing compressibility and improving hitching of the polishing cloth 14 and the abrasive 16 by increasing foaming density. The finishing polishing cloth 14 having this foaming density not less than 100 pieces/cm<2> and compresibility less than 7% is desirably used.
