Patent ID: 7238610

Claim:
A method of forming a semiconductor structure comprising: forming an ILD layer above a substrate, wherein said ILD layer has a top surface; forming a trench in said ILD layer, wherein said trench has a bottom surface and a sidewall surface; depositing a seed layer above said top surface of said ILD layer and above said bottom surface and said sidewall surface of said trench; depositing an inhibiting layer above the portion of said seed layer that is above said top surface of said ILD layer, but not above the portion of said seed layer that is above said bottom surface and said sidewall surface of said trench, wherein said inhibiting layer does not modify said seed layer, and wherein said inhibiting layer is comprised of a material selected from the group consisting of a wax, a grease, an oil or a surfactant; and depositing a metal layer above the portion of said seed layer that is above said bottom surface and said sidewall surface of said trench, wherein said inhibiting layer prevents the deposition of said metal layer above the portion of said seed layer that is above said top surface of said ILD layer.
