Abstract

It is a purpose of the invention to provide a semiconductor device comprising a high density integrated circuit having a large number of insulated gate field effect transistors having minute size and improved performance and uniformity. The source contact resistance is set in a value smaller than that of the drain contact resistance by making the diameter of a source contact of an insulated gate field effect transistor larger than that of the drain contact, so as to improve the current driving capability of the transistor and to reduce the variation in the capability.
