Abstract
A semiconductor structure having a cap layer formed over a metalized dielectric layer is formed by depositing manganese on the surface of the metalized dielectric layer. The deposited manganese serves as a first cap layer to remove oxidation on the surface of the metalized dielectric layer. The presence of oxidation on the surface of the metalized dielectric layer can be delirious for performance of a device constructed out of the semiconductor structure. A second cap layer is then formed by depositing silicon carbide or nitrogen enriched silicon carbide over the first cap layer.
