Abstract:
1. A method of manufacturing a semiconductor device, comprising: (a) obtaining a surface of a polishing target, wherein an insulating film and a metal film are exposed, and a part of said metal film is on said insulating film; and (b) polishing said surface having said exposed insulating film and said exposed metal film, wherein said step (b) includes: (b1) polishing said surface in a condition with high frictional force, and (b2) polishing said surface in a condition with usual frictional force lower than said high frictional force after said step (b1); wherein said step (b1) includes: (b11) polishing said surface under a high load, wherein said step (b2) includes: (b21) polishing said surface under a usual load lower than said high load after said step (b11) and wherein said step (b1) includes: (b11) polishing said surface under a high load for a duration of 1 to 15 seconds.
