Abstract
The combination of nanoimprint and UV-lithography has been demonstrated. For this purpose a UV-sensitive epoxy based resin with a low glass temperature was prepared by adding low molecular weight components, in particular by increasing the monomer content. The suitability of our approach to minimize process temperatures was tested by embossing and VU-lithography. Mix and match of both techniques was used to demonstrate that the embossing step did not degrade the UV sensitivity of the material. UV processing provided in addition a simple means for stabilization of this low Tg material. Resists like mr-L 6000-1 xp may close the gap between 'hot embossing' 'UV-molding' and UV-lithography.
