Patent attributes
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.
