A method for forming a strained metal silicon nitride film and a semiconductor device containing the strained metal silicon nitride film. The method includes exposing a substrate to a gas containing a metal precursor, exposing a substrate to a gas containing a silicon precursor, exposing the substrate to a gas containing a first nitrogen precursor configured to react with the metal precursor or the silicon precursor with a first reactivity characteristic, and exposing the substrate to a gas pulse containing a second nitrogen precursor configured to react with the metal precursor or the silicon precursor with a second reactivity characteristic different than the first reactivity characteristic such that a property of the metal silicon nitride film formed on the substrate changes to provide a strained metal silicon nitride film.
