PNPN SWITCH DEVICE |
摘要 |
<p>A PNPN switch device with a circuit for preventing an error due to a surge voltage. The circuit comprises two capacitors. The first capacitor is formed in a P-type gate region. The second capacitor of a capacitance of an insulation layer sandwiched between a MOS gate electrode and a capacitor electrode is provided outside the P-type gate region.</p> |
