摘要:
A semiconductor integrated circuit device includes: a master chip(203) including a basic cell region(201) having a plurality of basic cell arrays(206) arranged thereon, and an input/output cell region(202) having a plurality of input/output cells(207) arranged along the periphery of the basic cell region; a first wiring layer formed on the basic cell region and the input/output cell region via a first insulation layer having contact holes at predetermined positions, the first wiring layer including fixed wirings(LA,508); and a second wiring layer formed on the first wiring layer via a second insulation layer having through holes at predetermined positions, the second wiring layer including programmed wirings(LB,507). Only the wiring pattern of the second wiring layer is suitably changed in accordance with conditions of circuits applied to the input/output cell region and the basic cell region in regions corresponding to the input/output cell region and the basic cell region, thereby greatly reducing a turnaround time of the device.
