Abstract

An improvement of a resistance to electrostatic discharge of a semiconductor integrated circuit device is aimed. An IC having a high ESD immunity is realized by causing a surface concentration of N type impurities in a drain area of an N-channel type MOS transistor to be more than 5 E 18/cm.sup.3 in maximum in the direction of gate electrode of a gate electrode terminal and to have a monotonous concentration profile in which there is no kink in a portion less than 5 E 18/cm.sup.3 in the surface direction.
