The method involves directing alignment of self-assemblable block copolymer (BCP) composition in a trench in a resist layer on the substrate, having the substrate as base, with an epitaxy feature in the trench to cause the ordered BCP layer to have elongate domains stretching across the trench width, substantially parallel to each other and to the substrate. The ordered BCP layer is then used as a resist to pattern the substrate. A BCP composition adapted to assemble with spaced discontinuous elongate elliptical domains is disclosed. The method may allow for sub-resolution contact arrays to be formed using UV lithography.
