Title: Polishing method by alkaline suspension of silica particulate
Inventor: YOSHIDA KAZUAKI
IPC: B24B37/00
Filed: 2004-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a polishing method for improving a polishing speed by a polishing liquid including silica particulates, water and a basic substance.  <P>SOLUTION: This polishing method by an alkaline suspension of the silica particulates, improves the polishing speed by polishing by quickly supplying a mixed liquid 13 to a polishing surface by mixing a suspension 21 including the silica particulates and an aqueous solution 22 of the basic substance. That is, the suspension 21 including the silica particulates is set to high pH just before being used as the polishing liquid 13. This polishing method uses maintenance of high polishing force when using the suspension just after being prepared for the high pH since the polishing force reduces by dissolving the silica particulates in the suspension including the silica particulates of high pH.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
