1. A method for forming a MSiN dielectric film comprising the steps of:
a) vaporizing a metal source (M) to form a vaporized metal source;
b) providing a vapor phase silicon source, wherein said silicon source has a vapor pressure of at least 50 torr at about 20° C.;
c) feeding a plurality of precursors to a deposition device having a substrate disposed therein, wherein said precursors comprise said vaporized metal source, said silicon source, and a nitrogen source; wherein said nitrogen source and said silicon source comprise respective molecular structures absent carbon; and
d) forming the MSiN dielectric film on the substrate, wherein said dielectric film is formed from the said precursors in a single step such that the MSiN dielectric film is fully formed absent a post deposition step.
