Claim:
1. A method of manufacturing a semiconductor device, comprising: receiving film thickness distribution data indicative of a film thickness distribution of a polished first insulating film of a substrate; calculating processing data for reducing a difference between a film thickness at a center side of the substrate and a film thickness at a periphery side of the substrate, based on the film thickness distribution data; loading the substrate into a process chamber; supplying a process gas to the substrate; and correcting the film thickness distribution of the first insulating film by activating the process gas, based on the processing data, to form a second insulating film on the first insulating film, a concentration of active species of the activated process gas generated at the center side of the substrate differing from a concentration of active species of the activated process gas generated at the periphery side of the substrate.
