Patent ID: 8486489

Claim:
A method, comprising: applying a solution comprising two or more immiscible polymers to a substructure disposed on an exterior surface of a substrate, said exterior surface of the substrate having surface properties, said substructure comprising at least one feature having at least one sidewall and an adjoining bottom surface, said two or more immiscible polymers comprising a first polymer and a second polymer, said at least one sidewall comprising a first material, a selective chemical affinity of said first polymer for said first material being greater than a selective chemical affinity of said second polymer for said first material; segregating said first polymer from said second polymer, said first polymer selectively segregating to said at least one sidewall of said at least one feature, resulting in said first polymer being disposed between said sidewall and said second polymer to form a polymer segregation pattern in which said first polymer and said second polymer are distributed in a direction that is perpendicular to each sidewall of said at least one sidewall, wherein said first polymer and said second polymer have a same chemical affinity for the exterior surface of the substrate; and after said segregating, removing selectively one or more immiscible polymers of said two or more immiscible polymers, at least one immiscible polymer of said two or more immiscible polymers remaining on said substrate after said removing, resulting in forming structures on said substrate, said structures comprising said substructure and said at least one immiscible polymer remaining.
