Patent ID: 7875556

Claim:
A process for forming silicon nitride or silicon carbo-nitride films on a substrate through chemical vapor deposition of a silicon nitride or silicon carbo-nitride film forming precursor which comprises: using a precursor selected from the group consisting of an aminosilane represented by the formulas: and mixtures thereof, wherein R is selected from C 1 -C 10 alkyl groups, linear, branched, or cyclic, saturated or unsaturated; aromatic, heterocyclic, amine groups, or silyl in formula C, R 1 is selected from C 3 -C 10 alkyl groups, branched, or cyclic, saturated or unsaturated; aromatic, heterocyclic, hydrogen, silyl groups with or without substituents with R and R 1 in formula A also being combinable into a cyclic group (CH 2 ) n , wherein n is from 2-6, R and R in formula C also being combinable into a cyclic group and R 2 representing a single bond, (CH 2 ) m chain, a ring, SiR 2 , or SiH 2 and wherein R and R 1 in Formula A are each independently C 3 -C 10 branched alkyl groups.
