A DSC type device manufacturing process includes placing a circuit assembly in a mold. The circuit assembly includes a first heat sink, a semiconductor chip mounted on the first heat sink, a second heat sink mounted on the semiconductor chip and a pin block electrically connected to the semiconductor chip. An outer surface of the first heat sink and an outer surface of the pin block are placed in contact with a first inner surface of the mold. A spacer insert is placed in contact with, and positioned between, a second inner surface of the mold and an outer surface of the second heat sink. The mold is filled with an insulating material that is subsequently hardened. After hardening, a resulting device is extracted from the mold with the outer surfaces of the first heat sink, the pin block and the second heat sink exposed.
