Abstract:
A method for forming a micro-pattern on a substrate, the method comprising the steps of:(a) coating polymer material having a solvent on the substrate, thereby forming a polymer film on the substrate; (b) pressing a mold having a predetermined shape into the polymer film on the substrate by employing a predetermined compression technique to entail a plastic deformation of the polymer film, thereby patterning the polymer film; and (c) performing etching on the substrate through the use of the patterned polymer film as an etching mask, thereby forming a micro-pattern on the substrate, wherein the method further comprises the step of: (b1) before said step (b), increasing a free volume in the polymer film so that a pressure applied on the polymer material needed to plastically deform the polymer film is reduced.
