Patent ID: 8114300

Claim:
A method of forming a nanostructured polymer material on a substrate, comprising: depositing a block copolymer material within a trench in a material layer on the substrate to a thickness of about 5-30% less than a thickness of the block copolymer material to form surface parallel-oriented cylinders upon annealing, the trench having a length, and a floor, opposing sidewalls and ends that are preferentially wetting to a minority block of the block copolymer, and the block copolymer material having an inherent pitch value (L); and annealing the block copolymer material such that said block copolymer material self-assembles into a plurality of perpendicular-oriented cylindrical domains of the minority block within a matrix of a second block of the block copolymer, the cylindrical domains being aligned with the sidewalls in a single row for the length of the trench, and said cylindrical domains having a face exposed at an air interface with the self-assembled block copolymer material and an opposing end embedded within and surrounded by said matrix of the second block.
