Patent ID: 8722465

Claim:
A method of assembling a semiconductor device, comprising: providing a heat sink array structure having an array of heat sinks supported by a heat sink support frame and a plurality of tie bars, wherein each heat sink comprises a heat sink element having a top surface and a bottom surface, and an integral tie bar of the plurality of tie bars, extending outwardly from a side of the heat sink element; mounting a plurality of semiconductor dies on top surfaces of the heat sink elements; providing an electrically insulating substrate having an array of apertures and bearing electrical contact elements; assembling together said electrically insulating substrate and said heat sink array structure bearing said semiconductor dies, wherein said array of heat sinks is disposed in said array of apertures; connecting said semiconductor dies electrically with said electrical contact elements; encapsulating in a molding compound said semiconductor dies mounted on said array of heat sinks and assembled with said electrically insulating substrate; and singulating encapsulated units of said semiconductor dies with the corresponding heat sinks, surrounding portions of said electrically insulating substrate and electrical contact elements, wherein the bottom surface of the heat sink element, the second surface of the insulating substrate, and distal ends of the tie bars are exposed.
