Patent ID: 8133418

Claim:
A pattern transfer method, comprising: adjusting a relative position between a transferred object and a stamper having a concavo-convex pattern in a surface thereof; contacting and pressurizing a concavo-convex pattern plane of the stamper to the transferred object and thus transferring the concavo-convex pattern of the stamper to the transferred object; and detaching the stamper from the transferred object, wherein the step of adjusting a relative position between the transferred object and the stamper includes: taking at least one first two-dimensional image of two edge positions of the transferred object on at least one axis, compressing the at least one first two-dimensional image to at least one first one-dimensional image and calculating a center position of the transferred object on the at least one axis by performing a symmetry operation on the at least one first one-dimensional image; taking at least one second two-dimensional image of an edge of the stamper or two alignment marks formed in the stamper on the at least one axis where the at least one first two-dimensional image of the transferred object is taken, compressing the at least one second two-dimensional image to at least one second one-dimensional image and calculating a center position of the stamper on the at least one axis by performing a symmetry operation on the at least one second one-dimensional image; and adjusting a relative position between the transferred object and the stamper from a relation between the calculated center position of the transferred object and the calculated center position of the stamper.
