Patent ID: 8563086

Claim:
A method for forming a nano pattern, comprising: coating a part of a structural guide with a hydrophobic polymer, the structural guide including at least one protruded nano beam; selectively removing at least a part of the hydrophobic polymer coating of the at least one protruded nano beam to expose a portion of the at least one protruded nano beam leaving the hydrophobic polymer coating on an unexposed portion of the at least one protruded nano beam; after selectively removing the at least a part of the coating of the at least one protruded nano beam of the structural guide, positioning the coated unexposed portion of the at least one protruded nano beam of the structural guide on a surface of a substrate; after positioning the coated unexposed portion of the at least one protruded nano beam of the structural guide, coating at least a part of the surface of the substrate with a film made of a block copolymer, the block copolymer including: at least one hydrophobic block polymer; and at least one hydrophilic block polymer; annealing the film made of the block copolymer such that the hydrophobic polymer coating the unexposed portion of the at least one protruded nano beam of the structural guide causes the at least one hydrophobic block polymer of the film to align substantially according to a shape of the hydrophobic polymer coating the unexposed portion of the at least one protruded nano beam of the structural guide; and after annealing, selectively removing a part of the at least one hydrophilic block polymer of the film, leaving the at least one hydrophobic block polymer on the substrate.
