Abstract
An improvement is achieved in the performance of a semiconductor-device. The semiconductor device includes MISFETs formed in the upper surface of a substrate, a plurality of wiring layers stacked over the upper surface of the substrate, and a plurality of plugs each coupling two of the wiring layers to each other. The wiring layers located under the uppermost wiring layer include wires. The uppermost wiring layer includes a pad, an insulating film formed over the pad, and an opening extending through the insulating film and reaching the pad. The MISFETs and the wires overlap the opening in plan view. None of the plurality of plugs overlaps the opening in plan view.
