Abstract
A semiconductor device having a heat radiating member and a laminated structure for improvements in electrical and heat radiating characteristics. The heat radiating member is partially exposed outside a resin package of the semiconductor device to radiate heat generated by a semiconductor element to the outside of the device. In the laminated structure, a capacitor having a small capacity is formed by two electrically conductive plates one of which is connected to power supply leads and the other of which is connected to a grounded portion of the semiconductor element and to a grounding lead.
