Abstract: A semiconductor integrated circuit device includes a substrate structure layer including a substrate having a well and a diffusion region thereon, an interconnect layer including a pair of power supply lines arranged at a preset spacing from the substrate structure layer; the interconnect layer also including an input side interconnect and an output side interconnect between the pair of power supply lines, a standard cell having a logic circuit on the substrate; the logic circuit being electrically connected to the pair of power supply lines, the input side interconnect and the output side interconnect, and one or more capacitances arranged between the substrate structure layer and the interconnect layer and arranged in a region between the pair of power supply lines, the region being inclusive of a region superposed with the pair of power supply lines.

Abstract: A capacitance cell includes a substrate structure layer having pair diffusion regions, and an interconnect layer having pair of power supply lines. The capacitance cell also includes a capacitance composed of a first electrode, a dielectric member and a second electrode stacked together, and is formed in a frame shape and disposed in a space between the substrate structure layer and the interconnect layer so as to extend along an outer rim of the frame shape of a standard cell region in which a standard cell is arranged. The capacitance cell also includes a first substrate contact that electrically connects one of the pair of power supply lines to one of the diffusion regions externally of the standard cell region. The capacitance cell also includes a second substrate contact that electrically connects the other power supply line to the other diffusion region, externally of the standard cell region.
