Abstract:
1. A method of packaging a semiconductor device comprising the steps of: providing a first leadframe portion having a perimeter that defines a cavity and a plurality of leads extending inwardly from the perimeter, wherein the first leadframe portion has first and second sides and a first thickness; applying an adhesive to a first side of the first leadframe portion; providing a second leadframe portion including a die paddle having first and second surfaces and a second thickness that is greater than the first thickness; attaching a semiconductor die to the second surface of the die paddle using a high temperature die attach process, wherein the semiconductor die has a plurality of bonding pads on a surface thereof; stacking the second leadframe portion on the first leadframe portion such that the first surface of the die paddle is received within the cavity and contacts the adhesive; electrically connecting the plurality of die bonding pads with respective ones of the plurality of leads with a plurality of wires, wherein the wires are connected to the leads using a low temperature wire bonding process; forming a mold compound over the second side of the second leadframe portion, the semiconductor die, and the electrical connections; and removing the adhesive from the first side of the first leadframe portion and from the first surface of the second leadframe portion so that the leads and the first surface of the second leadframe portion are exposed.
