Abstract
A semiconductor device formed by using a standard cell system is a semiconductor device using a multi-layered wiring system. At this time, inter-cell wirings for electrically connecting different standard cells are formed of only a conductive layer which is disposed above a conductive layer constituting intra-cell wirings of the standard cells. Connection between the inter-cell wirings is made above an occupied area of the standard cells on the semiconductor substrate so as to eliminate a channel region.
