主 题：nanoimprinting electric-driven flexible-roller warped stress-sensitive
摘 要：Surface nanopatterning of semiconductor optoelectronic devices is a powerful way to improve their quality and ***,photoelectric devices’inherent stress sensitivity and inevitable warpage pose a huge challenge on fabricating nanostructures ***-driven flexible-roller nanoimprint lithography for nanopatterning the optoelectronic wafer is proposed in this *** flexible nanoimprint template twining around a roller is continuously released and recovered,controlled by the roller’s simple *** electric field applied to the template and substrate provides the driving *** contact line of the template and the substrate gradually moves with the roller to enable scanning and adapting to the entire warped substrate,under the electric *** addition,the driving force generated from electric field is applied to the surface of substrate,so that the substrate is free from external ***,liquid resist completely fills in microcavities on the template by powerful electric field force,to ensure the fidelity of the *** proposed nanoimprint technology is validated on the ***,nano-grating structures are fabricated on a gallium nitride light-emitting diode chip adopting the solution,achieving polarization of the light source.
