ABSTRACT:
A semiconductor device has a substrate comprising at least one dielectric layer and at least one metal layer on a first surface of the substrate. A die is attached to the first surface of the substrate. A mold compound is used to encapsulate the die and partially encapsulate the first surface of the substrate. The mold compound has a protrusion proximate to the at least one metal layer. A conductive material covers the mold compound, including the protrusion, and contacts the at least one metal layer.
