Abstract
PURPOSE:To obtain a protection diode effectively functioning without supplying a bias voltage thereto by forming a gate oxide film having desired charge at a part of an MOS semiconductor device and applying a potential effectively to the gate. CONSTITUTION:An N<+> type silicon layer 14 is formed on the first element region 13a isolated by the field silicon oxide film 12 of a P type silicon substrate 11. A gate oxide film 17 having negative charge made of alumina covering the P-N junction 16 of the peripheral edge of an N<+> type Si layer 14 and P type Si substrate 11 is formed on a gate oxide film 15 made of SiO2 formed on the surface of the element region 13a. A wire 20 is formed through an insulating film 18, and connected to the drain 22 of an MOS transistor. Negative potential is applied to the gate oxide film 17' by the negative load of the alumina layer 17, the breakdown voltage of the P-N junction is decreased to protect the drain.
