Title: Chemical mechanical polishing method and manufacturing method for semiconductor device
Inventor: MIZUNO NAOTO
IPC: B24B53/017
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a CMP method and a CMP treatment system which can carry out the conditioning of a polishing cloth efficiently by using a dresser having satisfactory efficiency for the polishing cloth. SOLUTION: In the CMP treatment system, the polishing cloth 221 is conditioned by using the dresser 233, comprising diamond grains having uniform diameters and arranged at equal intervals, with a low load, while a wafer 223 is subjected to CMP treatment. In the CMP treatment, polishing wastes of metal films, oxide films, etc., and polishing grains and chemicals, such as solvents, etc., in a slurry remain on the polishing cloth and they are accumulated over a long lapse of time to deteriorate a polishing rate. If the dresser is pressed against the surface of the polishing cloth for conditioning while a silicon semiconductor substrate having unevenness is polished, the polishing wastes and polishing grains can be removed without accumulation on the polishing cloth, so that the deterioration of the polishing rate can be suppressed.
