Abstract
Semiconductor integrated circuit of the present invention comprises a signal output terminal, a load circuit connected to the signal output terminal, a transistor circuit which is constituted by at least one first channel MOS transistor and has an output terminal connected to the signal output terminal and an input terminal connected to a signal input terminal, and a first channel enhancement type MOS transistor that is inserted between the transistor circuit's output terminal and the signal output terminal and is made normally in an on state. It is an object of the present invention to provide a highly reliable semiconductor integrated circuit in which no deterioration of characteristics due to hot carriers occurs even when the circuit is constituted using short channel MOS transistors with an effective channel length of about 1 micron or less.
