A method for forming a stressed passivation film. In one embodiment, the method includes depositing a silicon nitride film over an integrated circuit structure on a substrate and embedding oxygen into a surface of the silicon nitride film by exposing the silicon nitride film to a process gas containing oxygen radicals formed by non-ionizing electromagnetic radiation induced dissociation of an oxygen-containing gas or an oxygen- and nitrogen-containing gas. The method further includes heat-treating the oxygen-embedded silicon nitride film to form a stressed silicon oxynitride film.
