Abstract
An imprinting stamper which can transfer a microscopic pattern to a medium bearing a convex area or local projection, with high accuracy. A convexo-concave pattern is formed on a surface of the imprinting stamper. It includes a pattern layer having the convexo-concave pattern; and a stamper backside layer arranged on a backside of the pattern layer. Young's modulus of the pattern layer is 500 MPa to 10 GPa; and Young's modulus of the stamper backside layer is smaller than Young's modulus of the pattern layer.
