Each array is formed of a plurality of identical shapes repeating at every corresponding segmentation period, each shape having a predetermined length and a predetermined width. The shapes (protrusions or indentations) in the first array and the second array may have different lengths, in addition to the two arrays having different segmentation periods; a line feature on a template will thus appear asymmetric with respect to both the length and period of the shapes along the edges of the feature.
