Claim:
1. A semiconductor device package, comprising: a substrate; a metal pad formed on the substrate; a conductive element formed on the metal pad, wherein the metal pad electrically contacts the conductive element, and at least a portion of the conductive element is embedded in a molding compound, and wherein the conductive element has a recess away from the metal pad configured to provide an additional bonding interfacial area, and the recess has a first depth greater than a second depth from a top surface of the conductive element to a center of the conductive element; and a conductive connector bonded to the conductive element, wherein a melting point of the conductive element is higher than a melting point of the conductive connector, and the conductive connector is filled into the recess of the conductive element.
