A method of forming one or more inductors on a substrate is disclosed. The method includes forming a first dielectric material over the substrate, forming a trench in the first dielectric material, and substantially filling the trench with copper to form the one or more inductors. The first dielectric material is removed and a second dielectric material is formed over the copper. The second dielectric material is removed from an uppermost portion of the copper, thus leaving a portion of the second dielectric material on the sidewalls of the copper.
