  • Patent number: 9063408
    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.

  • Patent number: 8426025
    Abstract: The invention provides a modification of a polymer film surface interaction properties. In this process a polymer carrier object is covered by a chemical composition, comprising photo-polymerizable compounds, photo-initiators or catalysts with the ability to initiate polymerization and semi-fluorinated molecules. The so-produced polymer mold contains semi-fluorinated moieties, which are predominantly located on the surface and on the surface near region of the patterned surface. The polymer mold is suitable as a template with modified properties in a nano-imprint lithography process.
