Abstract:
A semiconductor integrated circuit device comprising:a substrate; and a plurality of basic-cells formed on said substrate, wherein each of said plurality of basic cells comprises one or more transistors pairs, each of said one or more transistors pairs include a transistor of a first conductivity type and a transistor of a second conductivity type, said one or more transistor pairs are arranged such that they can be selectively combined with each other, said transistor of a first conductivity type and said transistor of a second conductivity type in each of said transistor pairs share a gate electrode, the gate electrode of each of said one or more transistor pairs in at least one of said plurality of basic cells has a gate length different from that of the gate electrode of each of said one or more transistor pairs in another basic cell, at least one of a plurality of transistors is arranged in a direction different from the direction in which another transistor is arranged in each of the basic cells, wherein at least one of a plurality of transistors has a gate length different from that of another transistor in each of the basic cells.
