Abstract
Embodiments of the invention relate to methods and apparatus useful in the nanopatterning of large area substrates, where a movable nanostructured film is used to image a radiation-sensitive material. The nanopatterning technique makes use of Near-Field photolithography, where the nanostructured film used to modulate light intensity reaching radiation-sensitive layer. The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a movable film comprises metal nano holes or nanoparticles.
