Abstract:
1. A method of fabricating a semiconductor device comprising the steps of: (a) successively depositing a first insulating film and a conducting film at least including a metal on a semiconductor substrate; (b) patterning said conducting film and said first insulating film by etching with a photoresist film used as a mask into a gate electrode and a gate insulating film; (c) forming a second insulating film on at least an exposed portion of said semiconductor substrate through a reaction between oxygen and a semiconductor by subjecting, in an atmosphere including oxygen, said semiconductor substrate to plasma biased toward said semiconductor substrate, with said photoresist film kept; (d) removing said photoresist film; and (e) forming source/drain regions by introducing an impurity into regions positioned on both sides of said gate electrode in said semiconductor substrate.
