Abstract
A semiconductor device having a structure which can be manufactured with a higher yield includes a local interconnection layer(a first interconnection layer) on a semiconductor substrateand a global interconnection layer(a second interconnection layer) on the local interconnection layerThe local interconnection layerand the global interconnection layerinclude a local interconnection(a first interconnection) and a global interconnection(a second interconnection), respectively, and the global interconnectionis thicker than the local interconnectionThe local interconnection layerand the global interconnection layeralso have a dummy interconnection(a first dummy interconnection) and a dummy interconnection(a second dummy interconnection), respectively. The dummy interconnectionis narrower than the dummy interconnection
