ABSTRACT:
A semiconductor integrated circuit adaptable to any logic circuits using a common mask with the exception of a mask of metallic wirings so as to drastically improve performance of custom LSIs. The semiconductor integrated circuit comprises a logic circuit having a plurality of input terminals and at least one output terminal. The logic circuit includes a plurality of circuit blocks of the same circuit construction. Each of the circuit blocks has at least two stages of inverter formed by MOS semiconductor devices and at least one layer of a wiring pattern having a different pattern. The output signal of each block is defined by a predetermined function of an input signal.
