Abstract
A master slice type semiconductor integrated circuit which includes a semiconductor chip, input/output cells arranged in a peripheral portion of the semiconductor chip, and basic cells arranged in an entire central portion of the semiconductor chip excluding the peripheral portion of the semiconductor chip. Each of the basic cells are formed by a complementary metal oxide semiconductor (MOS) forming part and an N-channel metal oxide semiconductor (NMOS) forming part. The CMOS forming part forms a CMOS by employing same number of P-channel metal oxide semiconductor (PMOS) transistors and NMOS transistors, while the NMOS forming part forms a plurality of NMOS transistors on at least one end of the CMOS forming part in a direction parallel to the CMOS forming part.
