摘要: A method of patterning a block copolymer layer, the method including: providing a substrate including a topographic pattern on a surface of the substrate, wherein the topographic pattern includes a trench and a mesa; forming, on the surface of the substrate, an underlayer including a polymer, wherein the polymer includes a repeating unit derived from a substituted or unsubstituted aromatic vinyl monomer and has an anchoring group; heat-treating the underlayer to anchor the underlayer to the surface of the substrate via the anchoring group; irradiating the heat-treated underlayer with light to form a crosslinked polymer with a crosslink between carbon atoms of main chains of the polymer; forming a block copolymer layer on the underlayer including the crosslinked polymer; and heat-treating the block copolymer layer to form a self-assembled structure of the block copolymer directed by the topographic pattern.

摘要: A method of patterning a block copolymer layer includes: providing a guide pattern on a surface of a substrate, the guide pattern including sidewalls each elongated in a longitudinal direction and spaced apart from each other, a trench defined by a bottom surface and facing surfaces of the sidewalls, and having a uniform width over an entire length thereof in the longitudinal direction, and a latitudinal wall perpendicular to the longitudinal direction of the trench; providing a block copolymer layer on the surface of the substrate; and annealing the block copolymer to cause self-assembly of the block copolymer and to direct the same in the trench. The block copolymer has a microphase-separation into anisotropic discrete domains aligned with a period λo in the trench by the annealing.
