Abstract
A method and associated structure. A substrate is provided. The substrate has an energetically neutral corrugated surface layer. A film is formed on the corrugated surface layer. The film includes a combination of a di-block copolymer and a stiffening compound. The di-block copolymer includes lamellar microdomains of a first polymer block and lamellar microdomains of a second polymer block. The stiffening compound is dissolved within the first polymer block. At least one lamellar microdomain is removed from the film such that an oriented structure remains on the surface layer.
