Abstract: A patterning method using an imprint mold, to form an imprinted pattern structure, includes providing a resist layer from which the pattern structure will be formed, performing a first imprint process on a first area of the resist layer by using the imprint mold to form a first pattern of the pattern structure through deformation of the resist layer in the first area, and performing a second imprint process on a second area of the resist layer by using the imprint mold to form a second pattern of the pattern structure through deformation of the resist layer in the second area. The first and second areas are overlapped with each other in a third area of the resist layer, and the performing the second imprint process deforms a first portion of the first pattern in the third area to form the second pattern.
