| abstract |
A pattern-forming method includes forming on one face side of a substrate, a directed self-assembling film, and removing a part of the directed self-assembling film. The directed self-assembling film is formed from a composition including a block copolymer and a solvent. The block copolymer includes a first block composed of a first repeating unit that includes a silicon atom, a second block composed of a second repeating unit that does not include a silicon atom, and a first group that bonds to at least one end of a main chain and links to the first block. The first group is a monovalent group that forms a compound having ClogP of no less than 2.4 provided that a methyl group is bonded to an atom on a side of the main chain. The first group does not comprise a hetero atom. |
