Abstract: The invention to provide curable materials, comprising photo-reactive compounds, in particular, photoinitiators and polymerizable mono- or multifunctional monomers such as acrylates or epoxides. The material may also contain fluoro-surfactants completely or partly terminated by functional groups with the ability to bind covalently to said chemical composition under curing. The curable compositions are either purely acrylate based or a hybrid of different types of monomers such as acrylates, epoxides or vinyl ethers. The polymerizable monomers may cure with the use of different types of photoinitiator, such as free radical photoinitiators or cationic photoinitiators, ultimately forming a hybrid resist comprising interpenetrating networks of different types of monomers e.g. acrylates and epoxides. The acrylate/epoxide hybrid system has showed improved replication properties in terms of high nano-imprint lithography process fidelity, due to increased conversion of acrylates and low shrinkage.

Abstract: 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.

Abstract: The electrodeposited Nickel stamp is replicated from a conductive master, e.g. Titanium metallic master instead of a photoresist patterned master. The conductive layer is served as a working electrode in the subsequent electrodepositing of the Nickel metal. After the electroplating, Nickel stamps are obtained by peeling the Nickel metal sheet off the conductive layer of the metallic master. Low adhesion between metallic master and Nickel stamp make it possible to delaminate the Nickel stamp without any defects.
