Patent ID: 8227358

Claim:
A method of forming a silicon-containing film on a substrate comprising: a) providing a precursor having the formula: wherein Y is a hydrocarbyl group, a substituted hydrocarbyl group, oxygen, or an amino group; R 1 , R 2 , R 3 , and R 4 are each independently a hydrogen group, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, wherein R 1 , R 2 , R 3 , and R 4 may be the same or different from one another; X 1 , X 2 , X 3 , and X 4 are each independently a hydrogen group, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, or a hydrazino group, wherein X 1 , X 2 , X 3 , and X 4 may be the same or different from one another; b) vaporizing the precursor to form a vapor; and c) contacting the substrate with the vapor so as to form the silicon-containing film on the substrate.
