Patent ID: 8278150

Claim:
A method of packaging a semiconductor device, the method comprising: mounting an electrical component to an inner portion die pad, the die pad being a portion of a substrate strip component of a first leadless three-dimensional stackable semiconductor package; securing a plurality of bond wires from a plurality of bond pads on the electrical component to corresponding ones of a plurality of wirebond pads included on a leadless outer portion of the substrate strip component; selecting a sidewall of each of the plurality of wirebond pads, the sidewall having a height to be greater than a combined height of the electrical component and the inner portion die pad; and covering the electrical component, bond wires, and any exposed uppermost portions of the die pad with an encapsulating material to the uppermost portion of the sidewalls on the leadless outer portion, wherein an outer side surface of the sidewalls form a substantially continuous outermost edge of the semiconductor package.
