Abstract
A method of manufacturing a semiconductor device includes forming a first insulating film as a portion of a laminated insulating film on a substrate in which a plurality of circuit configurations is formed; polishing the first insulating film; measuring a film thickness distribution of the first insulating film; and forming a second insulating film as a portion of the laminated insulating film on the polished first insulating film at a film thickness distribution differing from the film thickness distribution of the first insulating film to correct a film thickness of the laminated insulating film.
