  • Publication number: 20070122749
    Abstract: A method of nanopatterning includes the steps of providing a resist film (12) and forming a pattern in the resist film (12). The resist film (12) includes a copolymer consisting of an organosilicone component and an organic component. An article (10) includes a substrate (14) and the resist film (12) disposed on the substrate (14). The copolymer of the organosilicone component and the organic component is sufficiently elastic, due to the presence of the organosilicone component, to be capable of resisting fracture and delamination during mold release. Furthermore, during pattern formation, the copolymer develops relatively low surface energy at an interface with the surface of a mold, as compared to conventional polymeric materials, and preferentially adheres to the substrate (14) rather than the mold, which provides for relatively easy mold release. The presence of the organosilicone component in the copolymer also allows the resist film (12) to exhibit excellent resistance to oxygen plasma etching.
