Abstract:
1. A method of fabricating a semiconductor device, comprising the steps of: forming an etching stopper film on a substrate; depositing an interlayer insulation film on said etching stopper film; and patterning said interlayer insulation film to form an opening, said step of forming said etching stopper film comprising the steps of: introducing said substrate into a reaction chamber of a processing apparatus; supplying an organic Si compound containing an organic silazane bond therein into said reaction chamber as a gaseous source; forming a plasma of the gaseous source in said reaction chamber; and depositing an SiNCH film containing Si, C, N, and H as primary constituent elements on a surface of said substrate as said etching stopper films, wherein said step of depositing said SiNCH film is conducted with such a plasma power that said silazane bond in said organic Si compound is substantially preserved in said SiNCH film.
