Method for producing a doped nitride film, doped oxide film and other doped films

摘要

Adding at least one non-silicon precursor (such as a germanium precursor, a carbon precursor, etc.) during formation of a silicon nitride, silicon oxide, silicon oxynitride or silicon carbide film improves the deposition rate and/or makes possible tuning of properties of the film, such as tuning of the stress of the film. Also, in a doped silicon oxide or doped silicon nitride or other doped structure, the presence of the dopant may be used for measuring a signal associated with the dopant, as an etch-stop or otherwise for achieving control during etching.
