A semiconductor device which is designed based on RDR, suppresses the occurrence of a trouble at the boundary between an active region and a power wire and therearound and is small in size and highly integrated. The semiconductor device includes a first conductive impurity region for functional elements which is formed over the main surface of a semiconductor substrate and a second conductive impurity region for power potential to which power potential is applied in at least one standard cell. It also includes insulating layers which are formed over the main surface of the semiconductor substrate and have throughholes reaching the main surface of the semiconductor substrate, and a conductive layer for contact formed in the throughholes of the insulating layers. The impurity region for functional elements and the impurity region for power potential are electrically coupled to each other through the conductive layer for contact which is formed astride the impurity region for functional elements and the impurity region for power potential.
