3-DIMENSIONAL ALIGNED NANOSTRUCTURE PREPARED BY BOTH IMPRINT LITHOGRAPHY AND LIFT-OFF PROCESSES, AND METHOD OF MANUFACTURING FOR THE SAME

摘要

PURPOSE: A 3-dimensional aligned nanostructure prepared by both imprint lithography and lift-off processes is provided to have a uniform size, various shape and constant arrangement by controlling the ratio of dry etching. CONSTITUTION: A manufacturing method a 3-dimensional aligned nanostructure comprises: a step of forming a polymer layer(102) on a substrate(101); a step of forming a photosensitive metal-organic material precursor layer on the upper part of the polymer layer; a step of preparing an imprint stamp; a step of pressurizing the photosensitive metal-organic precursor layer by the imprint stamp; and a step of forming a metal oxide thin-film pattern(105)by hardening the metal-organic precursor layer; a step of removing the imprint stamp from the metal oxide thin film pattern; a step of forming an undercut(106) by etching the polymer layer; a step of forming a metal oxide film(107); and a step of lift-offing the metal oxide thin film pattern and etching the polymer layer with an under cut.
