Master slice IC having n and p channel transistors

摘要

A semiconductor integrated circuit device of the master slice type which is suitable for use both in digital and analog circuits. The device includes a plurality of parallel basic elements, each including a plurality of p channel MOS transistors having gate electrodes connected commonly and source and drain regions separated from each other and a plurality of n channel MOS transistors having gate electrodes connected commonly and source and drain regions separated from each other. The source and drain regions of the p and n channel MOS transistors arranged in corresponding positions of the basic elements are common.
