Abstract:
A method of fabricating a semiconductor device, comprising the sequential steps of:forming an uppermost interlayer isolation film of SiO2 on a semiconductor substrate; forming an uppermost wire, having an upper surface and side surfaces, on an upper surface of said uppermost interlayer isolation film; forming a silicon oxide film on said uppermost interlayer isolation film by a plasma method to cover said uppermost wire; etching said silicon oxide film to form an etched back film of silicon oxide covering the upper surface and side surfaces of said uppermost wire and continuing etching to remove a portion of the upper surface of said uppermost interlayer isolation film not located under said uppermost wire and not under the etched back silicon oxide film; forming a nitride film on said uppermost interlayer isolation film to cover the etched interlayer isolation film; and forming a polyimide film on said nitride film.
