Abstract: 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.

Abstract: Methods are provided for depositing a low dielectric constant material. In one aspects, a method is provided for depositing a low dielectric constant material including introducing a processing gas comprising hydrogen and an oxygen-containing organosilicon compound, an oxygen-free organosilicon compound, or combinations thereof, to a substrate surface in a processing chamber and reacting the processing gas at processing conditions to deposit the low dielectric constant material on the substrate surface, wherein the low k dielectric material comprises at least silicon and carbon. The processing gas may further include an inert gas, a meta-stable compound, or combinations thereof. The method may further include treating the low dielectric constant material with a hydrogen containing plasma, annealing the deposited low dielectric constant material, or combinations thereof.
