    Abstract: A semiconductor package includes a pad and leads, the pad and leads including a base metal predominantly including copper, a first plated metal layer predominantly including nickel in contact with the base metal, and a second plated metal layer predominantly including silver in contact with the first plated metal layer. The first plated metal layer has a first plated metal layer thickness of 0.1 to 5 microns, and the second plated metal layer has a second plated metal layer thickness of 0.2 to 5 microns. The semiconductor package further includes an adhesion promotion coating predominantly including silver oxide in contact with the second plated metal layer opposite the first plated metal layer, a semiconductor die mounted on the pad, a wire bond extending between the semiconductor die and a lead of the leads, and a mold compound covering the semiconductor die and the wire bond.
