Patent ID: 7854873

Claim:
A method of use of a moldable polymer stamp composition, the composition comprising one or more Cyclic Olefin Copolymers (COCs) as a constituent of a polymer foil having a surface on which a structured pattern is formed for use in an imprint process, comprising the steps of: contacting a pattern of a surface of a template with a polymer material comprising the one or more Cyclic Olefin Copolymers (COCs) to produce a flexible polymer replica having a structured surface with an inverse of the pattern of the template surface; releasing the flexible polymer replica from the template surface; and pressing the inverse pattern of the flexible polymer replica into a surface of an object, to imprint a replica of the pattern of the template surface in the surface of the object; wherein a surface tension of the template surface (σ solid , template material) is lower than a surface tension of the polymer foil in the liquid state (σ liquid , polymer material), and further wherein a surface tension of the polymer foil in the solid state (σ solid , polymer foil) is lower than a surface tension of the surface of the object (σ liquid , resist material).
