Abstract
A semiconductor device has first wiring layersand a plurality of dummy wiring layersthat are provided on the same level as the first wiring layersThe semiconductor device defines a row direction, and first virtual linear lines Lextending in a direction traversing the row direction. The row direction and the first virtual linear lines Ldefine an angle of 2-40 degrees, and the dummy wiring layersare disposed in a manner to be located on the first virtual linear lines LThe semiconductor device also defines a column direction perpendicular to the row direction, and second virtual linear lines Lextending in a direction traversing the column direction. The column direction and the second virtual linear lines Ldefine an angle of 2-40 degrees, and the dummy wiring layersare disposed in a manner to be located on the second virtual linear lines L
