Abstract
An integrated circuit device includes insulated-gate field effect transistors employing a semiconductor gate electrode used as a logic element. Part of the input interconnection layer serves as the semiconductor gate electrode and orthogonally intersects with a conductive layer. The logic circuits are interconnected to constitute a random gate logic circuit that can be operated at high speeds and formed with a high density.
