Abstract
A semiconductor integrated circuit comprising a plurality of vertical static induction transistors (SITs) of normally-off type formed in a common semiconductor substrate in such a manner that the lateral dimension of the channel region of the SITs employed to form a hardware circuit region such as a logic circuit is designed greater than of the SITs which are employed to form a peripheral circuit region. Thus, it is possible to provide a semiconductor integrated circuit which concurrently satisfies a plurality of differently functioning semiconductor circuit requirements to exhibit different electric characteristics as represented by a high-speed operation and a high breakdown voltage.
