Abstract

PURPOSE:To upgrade integrity of the whole integrated circuit, by disposing a plurality of fundamental functional cells on spare regions inside the arrangement of input/output cells and recognition cells in a semiconductor chip. CONSTITUTION:A plurality of input/output buffer cells 2 and recognition cells 4 are arranged on respective peripheral sides of a semiconductor chip 1a, and a macro cell 3 with prescribed functions is disposed inside this arrangement, and power source wirings 5a are equipped. Fundamental function cells 6a to 6e with respective fundamental functions are disposed on spare regions inside the arrangement of the cells 2 and 4, and separate power source wirings 5a are equipped to connect these cells 6a to 6e. Wirings 7 are equipped for respective cells 2, 3, 6a to 6e, so as to compose semiconductor chips 1b with prescribed functions. Hence integrity of the whole semiconductor integrated circuit can be upgraded.
