Abstract
A method includes forming a first opening in a dielectric layer over a substrate, lining sidewalls and a bottom of the first opening with a conductive barrier layer, and depositing a seed layer over the conductive barrier layer. The method further includes treating the seed layer with a plasma process, and filling the first opening with a conductive material after the treating the seed layer.
