Abstract:
A method for making a semiconductor device, the method comprising:providing a substrate having at least coplanar first and second portions each including one or more leads, each said portion being electrically isolated from each other said portion; providing a semiconductor die having a first terminal electrically connected to a first conductive layer on a first surface of the die, and a second terminal electrically connected to a second conductive layer on an opposite second surface of the die; providing a metal strap having a cover portion at a first end thereof and an opposite second end, wherein said cover portion has a first surface and an opposite second surface; mounting the die on the substrate so that the first surface of the die faces the first portion of the substrate; attaching both the first conductive layer to the first portion of the substrate and the second end portion of the strap to the second portion of the substrate with an electrically conductive material; attaching the second conductive layer of the die to the first surface of the cover portion of the strap with an electrically and thermally conductive material; encapsulating the semiconductor die, at least a portion of the substrate, and the metal strap in a body of nonconductive material, while leaving the second surface of the cover portion of the strap exposed.
