PURPOSE:To enable to operate a semiconductor integrated circuit device at high speed even when the large scale logic circuit is constituted of a gate array by a method wherein a programmable logic array and the fundamental cells of the gate are integrally formed on the semiconductor substrate. CONSTITUTION:A PLA consisting of an AND circuit 6, an OR circuit 7, an input register 9 and an output register 11, which have been all disposed at the left lower part of a plane whereon fundamental cells 5 have been arranged, is subjected to a patterning. There is no trouble that the number of the PLA is plural pieces. Using this structure as a standard matrix body, a wiring layer on each wiring region 4 is formed and a semiconductor integrated circuit device is completed by connecting each element together. According to such a constitution, even when the circuit is enlarged on a large scale, the control of the circuit is simplified and the circuit can be actuated at high speed. As a result, the integration degree of the circuit can be improved and a large scale circuit can be designed in a short period. |
