Abstract: A pattern forming method includes forming a coating film containing a hydrophilic first homopolymer having a first bonding group and a hydrophobic second homopolymer having a second bonding group capable of bonding with the first bonding group, forming a bond between the first and second bonding group to produce a block copolymer of the first and second homopolymers, and heating the coating film to microphase-separating the copolymer into a hydrophilic domain and a hydrophobic domain. The hydrophilic and hydrophobic domains are arranged alternately. The bond is broken, then selectively dissolving-removing either domain by a solvent to provide a polymer pattern of a remainder domain.
