Patent ID: 8471049

Claim:
A method for forming a metal-containing film on at least a surface of a substrate comprising: forming via vapor deposition the metal-containing film on the surface from a composition comprising Group 4 metal-containing precursor having the following formula I: wherein M is Ti; R and R 1 are each independently selected from an alkyl group comprising from 1 to 10 carbon atoms; R 2 is an alkyl group comprising from 1 to 10 carbon atoms; R 3 is chosen from hydrogen or an alkyl group comprising from 1 to 3 carbon atoms; R 4 is an alkyl group comprising from 1 to 6 carbon atoms and wherein R 2 and R 4 are different alkyl groups; and at least one solvent selected from the group consisting of: an aliphatic hydrocarbon, an aromatic hydrocarbon, an ether, an ester, a nitrite, an amine, an organic amide, an alcohol, an imine, a carbodiimide, a ketone, an aldehyde, an amidine, a guandadine, an isourea, a glyme solvent having from 1 to 6 oxygen atoms and mixtures thereof wherein the viscosity of the composition at a temperature of 25° C. is 50 centipoise or less, wherein the vapor deposition is at least one selected from cyclic chemical vapor deposition, plasma enhanced chemical vapor deposition, or atomic layer deposition.
