Abstract
Electrodes of one face of a semiconductor, which has electrodes formed on both faces, and a heat radiating plate are directly joined to quickly absorb and diffuse heat of the semiconductor, thereby improving a heat radiation effect. At the same time, electrodes on an opposite face of the semiconductor are connected to pillared electrodes that are thicker than a wire for wire bonding and larger in current capacity. These pillared electrodes can accordingly be utilized as connecting terminals to a circuit board. Ceramic is used for the heat radiating plate, so that semiconductors of different functions can be mounted simultaneously.
