Patent ID: 8268209

Claim:
A pattern forming method of pressing a mold, in which a concavo-convex pattern is formed, against a substrate to which a resin film is applied, and thereby transferring this concavo-convex pattern to a surface of the substrate, wherein the mold has two or more alignment marks for determining a relative positional relation between the substrate and the mold, on a concentric circle, wherein alignment between the mold and the substrate is carried out from the relative positional relation between the alignment mark and an edge of a circular opening of the substrate, wherein the concentric circle, formed by the alignment mark, has a radius that is smaller than a radius of the circular opening of the substrate, and wherein the mold is a flat plate that has no opening at a position corresponding to the circular opening of the substrate, wherein the alignment mark on the mold does not transfer on the substrate when the mold is pressed onto the substrate, wherein a fine concavo-convex pattern and the alignment marks have different depths and wherein the alignment marks are arc shaped.
