Title: SEMICONDUCTOR DEVICE
Abstract:
Provided is a semiconductor device capable of providing sufficient wiring resources and reliably supplying a substrate power supply without an increase in the surface area. This invention is provided with: impurity diffusion regions formed in well regions; local wiring in contact with the impurity diffusion regions, the local wiring extending in the longitudinal direction; potential feed wiring formed in the layer above the local wiring, the potential feed wiring extending in the lateral direction; and contact holes for connecting the local wiring and the potential feed wiring to each other. A substrate potential is supplied to the well regions through the potential feed wiring, contact holes, local wiring, and impurity diffusion regions.
