Abstract:
1. A mold for imprint, comprising: a first pattern area comprising a first cyclic interval structure, which comprises a plurality of first recesses; and a second pattern area comprising a second cyclic interval structure, which comprises a plurality of second recesses, for being used as an alignment mark, wherein the first cyclic interval structure and the second cyclic interval structure have different depths, and wherein the first pattern area and the second pattern area have an equal cyclic interval, wherein the first cyclic interval structure and the second cyclic interval structure maintain continuity of the equal cyclic interval at a boundary between outermost surface portions of the first cyclic interval structure and the second cyclic interval structure, and wherein the equal cyclic interval is smaller than a size of the second pattern area, wherein the second pattern area is formed in two planes which are both parallel to a plane in which the first pattern area is formed, where one of the two planes is higher than the plane in which the first pattern area is formed and another of the two planes is lower than the plane in which the first pattern area is formed.
