Patent ID: 7442316

Claim:
A microcontact printing method using an imprinted nanostructure wherein microcontact printing is introduced to a nanoimprint lithography process to pattern a SAM (self-assembled monolayer), the method comprising steps of: forming a nanostructure on a substrate by using the nanoimprint lithography process; and patterning the nanostructure with a microcontact printing method, wherein the step of patterning comprises steps of depositing a metal thin film on the nanostructure, contacting a plate with the nanostructure to selectively print the SAM on the nanostructure wherein the SAM is inked on the plate and the metal thin film is deposited on the nanostructure, selectively removing the metal thin film by using the SAM as a mask, removing the SAM from the nanostructure, and patterning the substrate by using the remaining metal thin film on the nanostructure as a mask, wherein the step of selectively removing the metal thin film from the nanostructure by using the SAM as a mask is performed by selectively removing only the metal thin film deposited in channels between the embossed portions of the nanostructure.
