Abstract
A semiconductor device of an embodiment includes: a plurality of power lines extending in a first direction; and a plurality of cells arrayed along the first direction and a second direction intersecting the first direction and having a cell height of an integer multiple of a distance between the power lines adjacent to each other in the second direction, the cell height being a dimension in the second direction, wherein the plurality of cells include: a functional cell that contributes to a function of the semiconductor device; and a capacitance cell including a diffusion region of a first conductivity type and a gate electrode stacked above the diffusion region, and functioning as a decoupling capacitor, the capacitance cell is configured as a multi-height cell having a cell height of two or more times the distance, the capacitance cell includes a plurality of overlapping regions that are regions of the gate electrode overlapping the diffusion region in a stacking direction, the overlapping regions being aligned in the second direction, and the plurality of overlapping regions are arranged in one continuous well of a second conductivity type different from the first conductivity type.
