Abstract
A self-assembled film forming composition for forming a phase-separated structure of a block copolymer layer on a substrate, containing a block copolymer and a solvent, and is configured such that: the block copolymer is obtained by bonding a silicon-free polymer to a silicon-containing polymer that contains, as a constituent unit, styrene that is substituted by a silicon-containing group; the silicon-free polymer contains a structure derived from formula [1-1] or formula [1-2]; and the silicon-containing group contains one silicon atom. [In formula [1-1] or formula [1-2], each of Rand Rindependently represents a hydrogen atom, a halogen atom or an alkyl group having 1-10 carbon atoms; and each of R-Rindependently represents a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group having 1-10 carbon atoms, an alkoxy group having 1-10 carbon atoms, a cyano group, an amino group, an amide group or a carbonyl group.]
