Patent ID: 8133427

Claim:
A photo nanoimprint lithography comprising the steps of: discretely applying a photo-curable resist drop-wise onto a substrate; filling a first asperity pattern of a mold with the photo-curable resist by bringing the mold having the first asperity pattern formed therein into contact with the photo-curable resist; curing the photo-curable resist by irradiating the resist with a light; releasing from the mold the photo-curable resist which has been photo-cured to form a second asperity pattern on the photo-curable resist, which has been photo-cured; and forming an intermediary layer which has a larger interfacial tension than the surface tension of the photo-curable resist on a surface of the substrate and has a predetermined thickness before the step of discretely applying the photo-curable resist drop-wise onto the substrate, wherein the thickness the intermediary layer is determined so as to be commensurate with the etching resistance of the resist and the thickness of a base layer, with the thickness of the base layer including the intermediary layer being half or less than a half of the height of the second asperity pattern of the photo-curable-resist, wherein the intermediary layer is combined with the surface of the substrate through a chemical bond, wherein a functional group to be combined with the surface of the substrate is a silane coupling group.
