Abstract
A semiconductor integrated circuit device includes cells A-1, B-1, and C-1 that have the same logic. Cell B-1 has cell width Wlarger than a cell width of cell A-1, but gate length Lof a MOS transistor is equal to that of cell A-1. Cell C-1 has cell width Wequal to a cell width of cell B-1, but has a MOS transistor having large gate length L. A circuit delay of cell C-1 becomes large as compared with that of cells A-1 and B-1, but leak current becomes small. Therefore, by replacing cell A-1 adjacent to a space area with cell B-1, and by replacing cell B-1 in a path having room in timing with cell C-1, for example, leak current can be suppressed without increasing a chip area.
