Patent ID: 7910765

Claim:
A method of forming a silicon-containing film on a substrate, comprising contacting the substrate under vapor deposition conditions with a precursor of the formula [SiX n (NR 1 R 2 ) 3-n ] 2 selected from the group consisting of: (i) precursors of said formula wherein: R 1 =R 2 =C 3 -C 6 cycloalkyl; X is selected from the group consisting of halogen, hydrogen and deuterium; and 0<n<2; (ii) precursors of said formula wherein: at least one of R 1 and R 2 is H, and the other is selected from the group consisting of H, C 1 -C 5 alkyl, and C 3 -C 6 cycloalkyl; X is selected from the group consisting of halogen, hydrogen and deuterium; and 0<n<2; (iii) precursors of said formula wherein: one of R 1 and R 2 is H, and the other is C 1 -C 5 alkyl; X is selected from the group consisting of halogen, hydrogen and deuterium; and 0<n<2; and (iv) precursors of said formula wherein: one of R 1 and R 2 is H, and the other is ethyl or butyl; X is chlorine; and n is 0 or 1.
