Claim:
A reticle used for forming a plurality of vias for connecting a plurality of first wirings provided in a first wiring layer and a plurality of second wirings provided in a second wiring layer formed above the first wiring layer to each other, the plurality of first wirings and the plurality of second wirings being provided along one of a first direction and a second direction, the first direction and the second direction perpendicularly crossing each other, the reticle comprising a plurality of via opening patterns for forming the plurality of vias, wherein each of the plurality of via opening patterns has a rectangular shape, wherein the plurality of via opening patterns are arranged to cause each side of each of the plurality of via opening patterns to be diagonal with respect to both of the first direction and the second direction, and wherein a minimum distance between neighboring two of the plurality of via opening patterns, which are arranged diagonally with respect to the first direction and the second direction, is made to be larger, by rotating the plurality of via opening patterns with a center point of each of the plurality of via opening patterns being fixed, than a minimum distance between the plurality of via opening patterns when the plurality of via opening patterns are arranged to cause each side of each of the plurality of via opening patterns to be one of parallel to and perpendicular to the first direction and the second direction.
