Abstract
A substrate treatment method of treating a substrate using a block copolymer containing a hydrophilic polymer and a hydrophobic polymer, includes: a resist pattern formation step of forming a predetermined resist pattern by a resist film on the substrate; a thin film formation step of forming a thin film for suppressing deformation of the resist pattern on a surface of the resist pattern; a block copolymer coating step of applying a block copolymer to the substrate after the formation of the thin film; and a polymer separation step of phase-separating the block copolymer into the hydrophilic polymer and the hydrophobic polymer.
