  • Semiconductor integrated circuit device
    Patent number: 4862241
    Abstract: The inventive semiconductor integrated circuit device comprises a plurality of regularly disposed elementary units, each including a P channel MOS FET element paired with and an N channel MOS FET element. Desired ones of the elementary units each comprise a MOS field effect transistor having an ordinary form of a source-drain region formed by a diffusion region, while the remaining elementary units each have a diffusion region selectively connected to serve as a resistive element. Consequently, a desired circuit can be implemented without a resistive element being formed on each elementary unit.
