Patent ID: 8496841

Claim:
A nano patterning method, comprising: forming a polymer film having an electrification property on a surface of a stamp having convexed portions; contacting the stamp having the polymer film formed thereon, on a surface of a substrate, and applying a voltage between a metal layer of the stamp and the substrate; separating the stamp from the substrate, and transferring, onto the substrate, a remaining polymer film having an electrification region charged with negative charges (−) or positive charges (+); immersing the substrate including the remaining polymer film in a solution where thiol-terminated nanospheres are dissolved, thereby forming a nanosphere colloidal monolayer on a surface of the remaining polymer film in a self assembly manner; removing polymers absorbed to surfaces of the nanospheres, and an exposed portion of the polymer film except for a portion covered by the nanospheres; depositing a predetermined thin film on an entire surface of the substrate including a pattern of the nanospheres; and selectively removing the nanospheres and the thin film deposited above the nanospheres, thereby forming, on the substrate, a plurality of nano holes arranged in a hexagonal lattice with a predetermined period.
