COPOLYMER FORMULATION FOR DIRECTED SELF-ASSEMBLY, METHODS FOR MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a copolymer formulation for directed self-assembly.SOLUTION: This invention relates to a composition, comprising: a block copolymer, wherein the block copolymer comprises a first polymer and a second polymer, the first polymer and the second polymer of the block copolymer are different from each other, and the block copolymer forms a phase separated structure; an additive polymer, wherein the additive polymer comprises a bottlebrush polymer, and the bottlebrush polymer comprises a polymer that is chemically and structurally the same as one of the polymers in the block copolymer, or the bottlebrush polymer comprises a polymer that has a preferential interaction with one of the blocks of the block copolymers; and a solvent.SELECTED DRAWING: Figure 11
