ABSTRACT:
The present invention includes a method of determining an alignment between a substrate and a template spaced-apart from the substrate and having a distance defined therebetween, the substrate having a first pattern disposed thereon and the template having a second pattern disposed thereon, the method including, sensing the first and the second pattern, with the distance being established such that the first and the second pattern form a desired moiré pattern when the template and the substrate are in a desired spatial relationship.
