Abstract
A first cell having a cell height N times as large as a reference cell height (N is an integer equal to or more than 2) is adjoined by a second cell in the cell width direction. A diffusion interconnect made of an impurity diffusion region is formed under a metal interconnect for power supply in the second cell. The first cell includes a transistor diffusion region formed, opposed to the diffusion interconnect, so as to stride across a region extended in the cell with direction of the metal interconnect. The diffusion interconnect is placed apart from the cell boundary in the cell width direction.
