Patent ID: 7935575

Claim:
A method of forming a semiconductor package comprising: forming a first leadframe of the semiconductor package having a plurality of die attach areas on a first surface of the first leadframe wherein the plurality of die attach areas are separated from each other by a recess in the first surface including forming a support element of the first leadframe extending away from the first surface at a first angle; forming a second leadframe of the semiconductor package having a plurality of contact pads for electrically contacting electrodes of a semiconductor die wherein the electrodes are on a first surface of the semiconductor die including forming the second leadframe having a positioning element with a positioning feature that is formed to mate with the support element of the first leadframe; attaching the semiconductor die to a first die attach area of the plurality of die attach areas with a die attachment material; positioning the first leadframe over the second leadframe with the support element of the first leadframe mating with the positioning feature to position the electrodes of the semiconductor die to overlie at least a portion of the plurality of contact pads of the second leadframe; attaching the first and second contact pads of the second leadframe to the electrodes of the semiconductor die; and encapsulating the first and second leadframes with an encapsulating material wherein a portion of the plurality of contact pads are exposed to form first and second leads of the semiconductor package and wherein a distal end of the support element is exposed to form a third lead of the semiconductor package.
