Abstract:
1. A method of forming a dielectric film, comprising: introducing a source gas comprising Si, N, H, and optionally C and having at least one bond selected from Si—N, Si—Si, and Si—H into a reaction chamber where a substrate is placed; depositing a silazane-based film comprising Si, N, H, and optionally C on the substrate in a liquid or flowable state by plasma reaction at −50° C. to 50° C., wherein the film is free of exposure of a solvent comprising C, H, and optionally O; heat-treating the silazane-based film on the substrate in a heat-treating chamber while introducing an oxygen-supplying source into the heat-treating chamber to release C from the film and increase Si—O bonds in the film; and high heat-treating the film at a temperature of 700° C.-1,000° C. in an inert gas environment upon the heat treatment step.
