Abstract: Compositions for directed self-assembly patterning techniques are provided which avoid the need for separate anti-reflective coatings and brush neutral layers in the process. Methods for directed self-assembly are also provided in which a self-assembling material, such as a directed self-assembly block copolymer, can be applied directly to the silicon hardmask neutral layer and then self-assembled to form the desired pattern. Directed self-assembly patterned structures are also disclosed herein.
