Abstract
The present invention provides a method of manufacturing a semiconductor device, including the steps of forming a first film on an entire surface of a substrate having a recessed portion, including a bottom surface and a side wall of the recessed portion, without completely filling the recessed portion, forming a second film on an entire surface of the first film such that the recessed portion, on the bottom surface and the side wall of which the first film is formed, is completely filled, and polishing the first and second films by a chemical-mechanical polishing method such that the substrate is exposed and the first and second films in the recessed portion remain.
