Abstract:
1. A method for forming a dielectric film on at least one surface of a substrate by a deposition process chosen from a chemical vapor deposition process and an atomic layer deposition process, the method comprising: providing the at least one surface of the substrate in a reaction chamber; introducing at least one halogenated organoaminosilane precursor having the following Formula I: wherein X is a halide selected from the group consisting of Cl, Br, I; R 1 is independently selected from a linear or branched C 1 to C 10 alkyl group, a C 2 to C 12 alkenyl group, a C 2 to C 12 alkynyl group, a C 4 to C 10 cyclic alkyl, and a C 6 to C 10 aryl group; R 2 is selected from a linear or branched C 1 to C 10 alkyl group, a C 3 to C 12 alkenyl group, a C 3 to C 12 alkynyl group, a C 4 to C 10 cyclic alkyl group, and a C 6 to C 10 aryl group; R 3 is selected from a branched C 3 to C 10 alkyl group, a C 3 to C 12 alkenyl group, a C 3 to C 12 alkynyl group, a C 4 to C 10 cyclic alkyl group, and a C 6 to C 10 aryl group; m is 1 or 2; n is 0, 1, or 2; p is 0, 1 or 2; and the sum of (m+n+p) is less than 4 and wherein R 2 and R 3 are linked to form a ring; introducing a nitrogen-containing source into the reaction chamber wherein the at least one halogenated organoaminosilane precursor and the nitrogen-containing source react to provide the dielectric film on the at least one surface wherein the at least one organoaminosilane precursor is selected from the group consisting of 2,6-dimethylpiperidinodichlorosilane, 2,6-dimethylpiperidinochlorosilane, cyclohexylmethylaminochlorosilane, cyclohexylethylaminochlorosilane, and cyclohexyl-iso-propylaminochlorosilane.
