Abstract:
1. A method of forming a nanostructured polymer material on a substrate, comprising: forming a self-assembling block copolymer material within a trench in a material layer on the substrate, the trench having a length, a neutral wetting floor, and opposing sidewalls and ends that are preferentially wetting to a minority block of the block copolymer; applying a material preferentially wetting to the minority block over and in contact with the block copolymer material within the trench; and annealing the block copolymer material such that the block copolymer material self-assembles into one or more rows of half cylinders of the minority block of the block copolymer within a matrix of a majority block of the block copolymer, the one or more rows of half cylinders oriented parallel to the trench floor and extending the length of the trench, with a face oriented toward and wetting the neutral wetting trench floor.
