Abstract: PURPOSE:To prevent latch-up without forming a parasitic thyristor which exists in a semiconductor device using complementary MIS transistors, by forming source and drain diffused layer electrodes of the semiconductor device in a second-layer polycrystalline silicon film. CONSTITUTION:When a voltage higher than a threshold value of MIS transistors is impressed on a first gate electrode, a channel or an inversion layer is formed along 104 and 107. In the case when the voltage impressed between a source and a drain is sufficient enough for electrons in the inversion layer to go over a barrier of a second gate insulation film 107, on the occasion, the electrons flow into a drain electrode and, in addition, a part thereof goes over the barrier of the second insulation film 107 and is accumulated in a second-layer polycrystalline silicon film 103 insulated electrically from other electrodes. Thereby a threshold value voltage of the MIS transistors is shifted to be the higher when viewed from the first gate electrode.

Abstract: PURPOSE:To inhibit the hot carrier phenomenon of a fine MOS transistor and a logic circuit, etc. using the MOS transistor by increasing one N-channel MOS transistor to one logic transistor. CONSTITUTION:When an input signal to an input terminal 4 is a high level signal, a transistor 1 is turned ON, and a gate for a MOS transistor 2 is connected to a power supply VDD and the transistor 2 is turned ON at all times, thus outputting a low level signal to an output terminal 5.
