Abstract:
1. A method of packaging a semiconductor die, comprising: attaching an adhesive tape to a plate surface; forming lead fingers on the tape; forming a heat sink on the tape; providing a semiconductor IC die with bonding pads on a top surface thereof; placing a bottom surface of the die on the heat sink; electrically connecting respective ones of the die bonding pads with respective ones of the tape lead fingers with a plurality of wires, wherein the connections of the wires to the lead fingers are ball bonds; performing a reflow process on the die, the tape and the plate, wherein the ball bonds and the lead fingers melt during the reflow process and form controlled collapse chip carrier connection (C5) type interconnects when cooled; performing a molding process, wherein a mold compound is formed over the die and the tape; and removing the tape and the plate such that the heat sink and a surface of the C5 type interconnects are exposed.
