INSULATED-GATE SEMICONDUCTOR DEVICE |
摘要 |
Channel regions continuous with transistor cells are disposed also below a gate pad electrode. The channel region below the gate pad electrode is fixed to a source potential. Thus, a predetermined reverse breakdown voltage between a drain and a source is secured without forming a p+ type impurity region below the entire lower surface of the gate pad electrode. Furthermore, a protection diode is formed in a conductive layer disposed at the outer periphery of an operation region.
