Abstract:
1. A semiconductor device comprising first and second standard cells formed over a surface of a semiconductor substrate, wherein the first standard cell includes: a first functional device region formed over the surface of the semiconductor substrate; band-like first impurity diffusion regions formed over the surface of the semiconductor substrate and disposed opposedly to each other with both sides of the first functional device region therebetween; and metal layers disposed above the surface of the semiconductor substrate, the metal layers each including a trunk portion and an extending portion, the trunk portions of the metal layers extending above and along the first impurity diffusion regions respectively, the extending portions of the metal layers extending upwards of the first functional device region, wherein the second standard cell includes: a second functional device region formed over the surface of the semiconductor substrate; band-like second impurity diffusion regions formed over the surface of the semiconductor substrate and disposed opposedly to each other with both sides of the second functional device region therebetween, the second impurity diffusion regions being continuous with the first impurity diffusion regions respectively; and impurity diffusion regions for coupling formed over the surface of the semiconductor substrate to couple electrically between the second impurity diffusion regions and the second functional device region, and wherein the metal layers and the second functional device region are coupled electrically with each other through the trunk portions, the first impurity diffusion regions, the second impurity diffusion regions and the impurity diffusion regions for coupling.
