Patent ID: 7311946

Claim:
A process for forming a metal film on an at least one surface of a diffusion barrier layer, the process consisting of: providing the at least one surface of the diffusion barrier layer comprising at least one material selected from the group consisting of a metal carbide, a metal nitride, a metal carbonitride, a metal silicon carbide, a metal silicon nitride, a metal silicon carbonitride, and mixtures therefrom, and wherein the diffusion barrier layer has an orientation of at least 95% substantially (111) preferred orientation; and forming the metal film on at least a portion of the surface by either a chemical vapor deposition process or an atomic layer deposition process with at least one organometallic precursor, wherein the organometallic precursor comprises a metal selected from the group consisting of copper, platinum, nickel, cobalt, palladium, ruthenium, rhodium, inidium, gold, and silver.
