Patent ID: 8283758

Claim:
A microelectronic package, comprising: a semiconductor die having a bond site at a first side and a second side opposite the first side, the semiconductor die further including a thermally conductive material formed on the second side of the semiconductor die; a lead frame proximate the semiconductor die, the lead frame having a lead finger; a solder ball between the bond site of the semiconductor die and the lead finger, the solder ball forming an electrical connection between the bond site of the semiconductor die and the lead finger of the lead frame; an encapsulant at least partially encapsulating the semiconductor die, the lead frame, and the solder ball, the encapsulant having a first surface opposite a second surface, and the encapsulant also including a plurality of openings extending toward the semiconductor die from the second surface; and wherein the plurality of openings individually expose a portion of the thermally conductive material and the thermally conductive material is generally solderable.
