Patent ID: 8097936

Claim:
An apparatus comprising a first component and a second component stacked onto the first component, the first component comprising: a first device carrier comprising a first device carrier lead and a second device carrier lead, the first and second device carrier leads of the first device carrier being electrically insulated from one another; a first device applied to the first device carrier, the first device comprising a first device contact and a second device contact, the first and second device contacts being electrically insulated from one another; an insulating layer arranged at least partially on the first device carrier and the first device; a first conducting layer grown onto the first device, the first device carrier, and the insulating layer, wherein the first conducting layer electrically connects the second device contact with the second device carrier lead of the first device carrier; a heat sink formed by a portion of the first conducting layer overlying the second device contact, the heat sink portion having a larger layer thickness than a remainder of the first conducting layer and being electrically continuous with the remainder of the first conducting layer; and an insulating material applied to the first conducting layer, the insulating material defining a first package within which the first device carrier, the first device, and the first conductive layer are embedded such that the heat sink is exposed to a surface of the first package, wherein the first device is a semiconductor device, and wherein the first device contact is a drain contact and the second device contact is a source contact; the second component comprising: a conductive second device carrier comprising a first device carrier lead of the conductive second device carrier and a second device carrier lead of the conductive second device carrier insulated from one another; and a second device mounted to the conductive second device carrier; wherein the second component is mounted to the surface of the first package with one of the device carrier leads of the conductive second device carrier coupled to the heat sink of the first component, and wherein the second device carrier lead of the conductive second device carrier is electrically connected to the second device carrier lead of the first device carrier by a first via through the insulating material of the first package.
