Abstract:
1. A method of forming a nanostructure having a high aspect ratio, comprising: forming a polymer thin film on a substrate; contacting a mold with the polymer thin film evenly by applying 0.1 to 10 atmospheric pressure to the mold; forming a polymer pattern contacting a background surface of an engraved part of the mold by making the polymer thin film flow based on the capillary phenomenon; and forming a nanostructure with the polymer pattern extended out by removing the mold out of the polymer thin film with the polymer pattern formed thereon, wherein a surface energy difference between the substrate and the polymer thin film is less than a surface energy difference between the polymer thin film and the mold, and an extent of the extension of the polymer pattern is controlled by adjusting the surface energy difference between the polymer thin film and the mold.
