Abstract
Soft ultraviolet nanoimprint lithography is a cost-effective and versatile technique for the transfer of nano-scaled patterns to various surfaces. Here, we report on the fabrication of sub-micron square pillar arrays in epitaxial Ba 0.7Sr 0.3TiO 3 ceramic films, using a combination of nanoimprint lithography and inductively coupled plasma etching techniques. Based on a similar approach we have also succeeded in preparing positive (direct) and negative (inverse) replicas of silicon master molds. Such a generic process could find application in various materials.
