Abstract:
1. A method of producing a structure containing a phase-separated structure, comprising: applying an undercoat agent to a substrate, so as to form a neutralization film on the substrate; applying a block copolymer composition to the neutralization film, so as to form a block copolymer layer on the neutralization film, the block copolymer having a PA block and a PB block being mutually bonded; and annealing the block copolymer layer; and forming a phase-separated structure selected from the group consisting of a PA matrix cylindrical structure, a lamellar structure, or a PB matrix cylindrical structure, wherein a surface free energy of the P wherein, when the phase-separated structure is the P wherein, when the phase-separated structure is the lamellar structure, the coordinate point N of the neutralization film is within the range of an ellipse E, wherein a point 0 is a center of the ellipse E and divides a line segment AB in the ratio of 5:5, the line segment AB is on a minor axis of the ellipse E, a minor radius of the ellipse E is 0.6 times the length of the line segment AB, and a major radius of the ellipse E is 3 times the length of the line segment AB; and wherein, when the phase-separated structure is the P
