Hybrid topographical and chemical pre-patterns for directed self-assembly of block copolymers

Hybrid pre-patterns were prepared for directed self-assembly of a given block copolymer capable of forming a lamellar domain pattern. The hybrid pre-patterns have top surfaces comprising independent elevated surfaces interspersed with adjacent recessed surfaces. The elevated surfaces are neutral wet...
