Patent ID: 7812437

Claim:
A molded leadless package (MLP) semiconductor package assembly comprising: a planar contact pad with one or more first lands extending toward one edge of the packaged assembly; a second land in the same plane as the contact pad and disposed along the same edge as the one or more first lands; a set of electrically isolated, connectable lands in the same plane as the contact pad and disposed along an edge opposite from the first lands; a semiconductor die having both a first terminal and a second terminal on a bottom surface as well as a third terminal on a top surface, with the first terminal mounted to the contact pad to connect the first terminal to the first lands and the second terminal to the second land, the set of connectable lands being electrically isolated from the first, second and third terminal; a folded heat sink with a perimeter, the heat sink forming both an exposed upper surface and an exposed vertical edge of the package, the heat sink having a planar element contacting the third terminal of the semiconductor die and at least one third land that extends perpendicular to the contact pad to form the exposed vertical edge, the third land being disposed along the edge opposite from the first lands and terminating proximate to, but electrically isolated from, the set of connectable lands, the set of connectable lands and the third land being separated by an empty gap, the connectable lands being disposed entirely within the perimeter of the folded heat sink; a molding material with a top surface that is coplanar with the top surface of the semiconductor die.
