  • Patent number: 8303291
    Abstract: Imprint templates for use in nanoimprint lithography methods, a nanoimprint device suitable for UV nanoimprint lithography methods and a nanostructuring method for direct structuring of a UV-sensitive imprint material on a substrate are provided. The imprint templates, nanoimprint device and nanostructuring method can be used both for ultraviolet nanoimprint lithography and for thermal nanoimprint lithography. The imprint template includes a nontransparent structured chip and a transparent substrate. An at least partially nontransparent imprint template as well as a UV source situated above the imprint template holder are used for structuring by indirect exposure by reflection of light emitted from the UV radiation source in the direction of a photoactive layer.
