MANUFACTURING METHOD FOR STRUCTURE INCLUDING PHASE SEPARATION STRUCTURE, BLOCK COPOLYMER COMPOSITION AND ORGANIC SOLVENT USED FOR BLOCK COPOLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for a structure including a phase separation structure.SOLUTION: A manufacturing method for a structure including a phase separation structure comprises a step A of coating a substrate with a block copolymer composition, containing a block copolymer, which is a couple of a block consisting of polystyrene or a polystyrene derivative with other blocks of one or more kinds, and an organic solvent component (S) to form a layer containing the block copolymer and a step B of phase-separating the layer containing the block copolymer, where the value of the interaction distance Ra(MPa) between a Hansen solubility parameter of the organic solvent component (S) and a Hansen solubility parameter of the polystyrene or the polystyrene derivative satisfies the following expression (1).SELECTED DRAWING: None
