Abstract
A semiconductor device is fabricated by steps of forming, by atmospheric pressure CVD or low pressure CVD without using plasma, a first insulating layer that covers a semiconductor substrate having a protruded and recessed surface; forming, by bias plasma CVD using an electron cyclotron resonance process, a second insulating film that covers the first insulating layer; and planarizing the second insulating film by a CMP process. In this way, the time required for planarizing a surface of the semiconductor substrate by the CMP can be reduced.
