Abstract:
A method of manufacturing an imprint stamp including forming an imprint resist only in a second area of a sample substrate including a first area and the second area, pressing the imprint resist with the imprint stamp and curing the imprint resist, in which the imprint stamp includes a fine protrusion pattern that corresponds to the first area and the second area of the sample substrate, and separating the imprint stamp from the sample substrate such that a portion of the fine protrusion pattern corresponding to the second area is separated from the imprint stamp by the cured imprint resist.
