A method for depositing a low k dielectric film comprising silicon, carbon, and nitrogen is provided. The low k dielectric film is formed by a gas mixture comprising a silicon source, a carbon source, and NR1R2R3, wherein R1, R2, and R3 are selected from the group consisting of alkyl and phenyl groups. The low k dielectric film may be used as a barrier layer, an etch stop, an anti-reflective coating, or a hard mask.
