Abstract:
1. Nanoimprint device for UV nanoimprint lithography methods, comprising: a chuck accommodating a substrate with a layer of photoactive material situated on the substrate, a holder accommodating an imprint template, the template being positioned by adjusting the holder above the substrate, and a UV radiation source situated above the imprint template, wherein the template comprises an unstructured substrate and a structured chip fastened to the unstructured substrate, the structured chip containing a negative imprint structure and having side edges of lengths smaller or as long as corresponding side edges of the unstructured substrate, the structured chip consisting of a material nontransparent to ultraviolet light and the unstructured substrate comprising a material transparent to ultraviolet light, the photoactive material layer of the substrate to be imprinted is shaded from direct exposure to the UV radiation source by the nontransparent material of the structured chip, and all components are arranged to facilitate reflection of ultraviolet light emitted from the UV radiation source to an underside of the shaded photoactive material layer.
