Abstract:
A packaged semiconductor device, comprising:a substrate having a first portion with a first lead connected thereto, a second portion electrically isolated from the first portion and having a second lead connected thereto, and a third lead electrically isolated from the first and second portions; a semiconductor die having top and bottom surfaces and an active electronic device formed therein, the device having a first terminal connected to a first conductive layer on the bottom surface of the die, a second terminal connected to a second conductive layer on the top surface of the die, and a third terminal connected to a third conductive layer on the bottom surface of the die, the third conductive layer being electrically isolated from the first conductive layer; and, a metal strap having a cover portion, a flange portion, and a down-set portion between the cover and flange portions, the first conductive layer on the die being attached to a top surface of the first portion of the substrate with a first joint of an electrically conductive material, the cover portion of the strap being attached to the second conductive layer on the die with a second joint of an electrically conductive material, the flange portion of the strap being attached to a top surface of the second portion of the substrate with a third joint of an electrically conductive material, and the third conductive layer on the die being attached to a top surface of the third lead with a fourth joint of an electrically conductive material, wherein the top surface of the second portion of the substrate has a recess therein, and wherein the flange portion of the metal strap is captivated within the recess.
