Abstract

A first dummy via pattern having high density is arranged in the vicinity of first and second wirings on a semiconductor device, and a second dummy via pattern having low density is arranged in a distant region from the first and second wirings, with reference to the first dummy via pattern. Accordingly, it is possible to suppress expansion of the file size of layout CAD data due to dummy vias, while complying with a design standard regulated for each semiconductor process, regardless of the presence or absence of vias which connect the first wirings to the second wirings.
