Abstract

PURPOSE:To obtain a protective circuit which can prevent a short between a drain and gate and has low PN-junction dielectric strength and high discharge performance. CONSTITUTION:Input terminal 3 is connected to N-type drain layer 12 of MOSFET9 via N layer 6 in a P-type substrate, and Al wiring 11 is led to input gate 1. The gate electrode of protective FET9 is connected to earth line 17. Source 14 and poly-Si resistance 10 are connected together via the Al wiring and then connected to earth line 17 at opening part 16. Source and drain terminals are pointeed. When a large electrostatic voltage is applied, an avalanche breakdown starts in the pointed region at a low voltage and produced positive holes decrease the potential of the substrate to discharge static charges. By this current and resistance 10, the source potential risis, so that the discharge will stop. Since those are carried out momently, charges are not injected until a short occurs between the drain and gate. In this way, MOSFET1 can be protected.
