Abstract
A gate array includes a plurality of basic cells which each include normally-on type transistors and a plurality of normally-off type transistors. The source electrode, drain electrode and gate electrode of each normally-off type transistor are not connected in common to the electrodes of the other transistors in the cell. Thus, a desired number of normally-off type transistors can be connected to a particular normally-on type transistor by wiring. Thus, unnecessary connections of normally-off type transistors to a normally-on type transistor can be avoided.
