Abstract:
1. A method of producing a structure containing a phase-separated structure, the method comprising: (1) forming, on a substrate, a layer containing a block copolymer having a block of a polyhedral oligomeric silsesquioxane structure-containing structural unit, (2) forming a top coat film by applying, to the layer containing the block copolymer, a top coat material comprising a polymeric compound having a structural unit (Tc1) which undergoes a change in s polarity upon heating and a structural unit (Tc2) which controls a surface energy of the layer containing the block copolymer, and (3) subjecting the layer containing the block copolymer with the top coat film formed thereon to phase separation by thermal annealing.
