Abstract
A method for manufacturing a semiconductor device is disclosed. A semiconductor substrate such as bare silicon is provided, and a dielectric layer is formed over the semiconductor substrate. An opening is provided within the dielectric layer by removing a portion of the dielectric layer. A conformal first conductive layer is formed over the dielectric layer and the opening. A conformal second conductive layer is formed over the first conductive layer. A conformal barrier layer is formed over the second conductive layer.
