Abstract:
A template for producing an image, the template characterized by a minimum template size, the template comprising:a feature having a nominal size and having a first edge and a second edge opposite the first edge; and a first array of shapes and a second array of shapes disposed on the first edge and second edge respectively, each of the first array and the second array being one of an array of protrusions from the feature and an array of indentations in the feature, the first array and the second array having a first segmentation period and a second segmentation period measured along the first edge and the second edge respectively, the first segmentation period being different from the second segmentation period so that the first array is different from the second array, thereby causing the feature to be asymmetrical, wherein said template causes the image to have a size differing from the nominal size by an increment which is a fraction of the minimum template size.
