ABSTRACT:
A high impedance can be maintained at a back gate of a MOS transistor constituting a CMOS integrated circuit when power is not supplied, and is switched to an impedance lower than the impedance in use of the CMOS integrated circuit by a switch driven by a power supply of the CMOS integrated circuit. Thus, it is possible to prevent surge breakdown and electrostatic breakdown, and to prevent occurrence of latch up breakdown.
