Abstract
A silicon nitride or silicon oxynitride film is deposited by plasma enhanced chemical vapor deposition from a precursor gas mixture of a silane, a nitrogen-containing organosilane and a nitrogen-containing gas at low temperatures of 300.degree.-400.degree. C. and pressure of 1-10 Torr. The silicon nitride films have low carbon content and low hydrogen content, low wet etch rates and they form conformal films over stepped topography.
