Abstract

An integrated circuit device includes a plurality of basic cells that each have a first transistor pair including two p-channel transistors of a first-type and a second transistor pair including two p-channel transistors of a second-type. The second-type transistors are configured to consume less power and operate more slowly than the first-type transistors. The basic cell further includes a third transistor pair of two n-channel transistors of a third-type. The third transistor pair is disposed between the first and second transistor pairs. Gate electrodes are separately provided for each transistor in the first, second, and third transistor pairs. The basic cell thus formed can be used to fabricate various circuit elements by making wiring connections between various transistor pairs and/or basic cells.
