US Patent 7854873 Imprint stamp comprising cyclic olefin copolymer

A method is provided for transferring a pattern from a template (1) to an object (12) in an imprint process, using a two-step process. The first step includes contacting a pattern of the template surface with a polymer material comprising 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. In a second step, after releasing the flexible polymer replica from the template, the inverse pattern of the flexible polymer replica is pressed into a resist layer on a substrate, to imprint a replica of the pattern of the template surface in therein.
