Patent ID: 8343578

Claim:
A method, comprising: providing a di-block copolymer, said di-block copolymer comprising a first block of a first polymer, said first block being covalently bonded to a second block of a second polymer to form a repeating unit of the di-block copolymer, said first and second polymers being different; providing a substrate having an energetically neutral surface layer, said surface layer having a corrugation integrally disposed thereon, said corrugation characterized by a direction of corrugation; providing a third material, said third material being miscible with said first polymer; combining said di-block copolymer with said third material to form a combination of said di-block copolymer and said third material; forming a film of said combination onto said corrugated surface layer; and assembling lamellar microdomains of said di-block copolymer within said film, said microdomains forming self-assembled structures within said film, said structures having an orientational direction substantially normal to said direction of corrugation and substantially parallel to said surface layer, wherein presence of said third material within said first block induces lamellar microdomains of said di-block copolymer to align with respect to said corrugated surface layer, after said film is formed on said corrugated surface layer.
