Title: Polishing method
Inventor: KURATA YASUSHI
IPC: H01L21/304
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To polishe the surface of an SiO2 insulating film or the like at a high speed without flaws by a method in which a passivation film is formed only on the surface of a specific film out of the formed layers so as to prevent it from being continuously polished, and the other films are selectively polished.
