    Abstract: A method is disclosed to form a row of mutually spaced elongate lithography features along an axis on a substrate, for instance for use as contact electrodes for a NAND device. 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.

    Abstract: A method of forming a patterned chemical epitaxy template, for orientation of a self-assemblable block copolymer including first and second polymer blocks, on a surface of a substrate, the method including applying a primer layer of a primer composition to the surface, the primer composition including a first polymer moiety having a chemical affinity with the first polymer blocks and a second polymer moiety having a chemical affinity with the second polymer blocks, selectively exposing the surface, the primer layer and any overlying layer to actinic radiation to provide exposed and unexposed regions, to render labile the first polymer moiety in the exposed region, and removing the labile first polymer moiety from the exposed region to deplete the primer layer surface in the exposed region of first polymer moiety to form the patterned chemical epitaxy template.
