Patent 8192920 was granted and assigned to Rolith on June, 2012 by the United States Patent and Trademark Office.
Embodiments of the invention relate to lithography method useful for patterning at sub-micron resolution. This method comprised of deposition and patterning self-assembled monolayer resists using rolling applicator and rolling mask exposure apparatus. Typically the application of these self-assembled monolayers involves contacting substrate materials with a rotatable applicator in the shape of cylinder or cone wetted with precursor materials. The nanopatterning technique makes use of Near-Field photolithography, where the mask used to pattern the substrate is in contact with self-assembled monolayer. The Near-Field photolithography may make use of an elastomeric phase-shifting mask, or may employ surface plasmon technology, where a rotating mask surface comprises metal nano holes or nanoparticles.
