Patent ID: 8101261

Claim:
A method of forming a nanostructured polymer material on a substrate, comprising: forming a self-assembling block copolymer material within a single trench or a plurality of trenches having ends not aligned, said trench(es) in a material layer on the substrate, the trench(es) having a neutral wetting floor, and opposing sidewalls and ends that are preferentially wetting to a minority block of the block copolymer; and annealing the block copolymer material such that said block copolymer material self-assembles into cylindrical domains of the first block of the block copolymer within a matrix of a second block of the block copolymer, said self-assembled block copolymer material having a thickness, and the cylindrical polymer domains oriented perpendicular to the trench floor and extending through said thickness of the self-assembled block copolymer material in a one-dimensional (1-D) array of a single row for the length of the trench(es).
