Abstract

A packaged semiconductor device includes a semiconductor die including a substrate having a topside including active circuitry and a bottomside with at least one backside metal layer directly attached. A package including a molding material having a die pad and a plurality of leads is encapsulated within the molding material, wherein the leads include an exposed portion that includes a bonding portion. The topside of the semiconductor die is attached to the die pad, and the package includes a gap that exposes the backside metal layer along a bottom surface of the package. Bond wires couple pads on the topside of the semiconductor die to the leads. The bonding portions, the molding material along the bottom surface of the package, and the backside metal layer are all substantially planar to one another.
