A method of forming a variable pattern across a wafer using a reticle forms a plurality of first patterns on the wafer. The first pattern is repeated across the wafer and each first pattern has a first readable element. The method also forms a plurality of second patterns on the wafer. The second patterns is repeated across the wafer and each second pattern has a second readable element. The second patterns are positioned relative to the first patterns by aligning a first second pattern relative to one portion of a corresponding first pattern and then incrementally misaligning each successive second pattern in a row or a column relative to its corresponding first pattern. Thus, each corresponding first readable element and second readable element form a corresponding variable pattern.
