Abstract: 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.
