ABSTRACT:
A semiconductor device includes a semiconductor chip and leads electrically connected to the electrodes of the semiconductor chip. A hollow radiator base houses the semiconductor device which is molded with high-thermal-conductivity resin having an electrical insulating property. The radiator base has a cooling-medium channel therein or radiating fins on the outside. Alternatively, the radiator base is housed in a second radiator base.
