Abstract

A local interconnect is formed in contact with an upper surface of an impurity diffusion region and extends to below a potential supply interconnect. A contact hole electrically couples the local interconnect to the potential supply interconnect. The local interconnect, which is formed in contact with the upper surface of the impurity diffusion region, is used for electrically coupling the impurity diffusion region to the potential supply interconnect.
