Substrate treatment method, computer readable storage medium and substrate treatment system

A substrate treatment method includes: forming a plurality of circular patterns of a resist film on a substrate; thereafter applying a first block copolymer; then phase-separating the first block copolymer into a hydrophilic polymer and a hydrophobic polymer; thereafter selectively removing the hydr...

Zusammenfassung:A substrate treatment method includes: forming a plurality of circular patterns of a resist film on a substrate; thereafter applying a first block copolymer; then phase-separating the first block copolymer into a hydrophilic polymer and a hydrophobic polymer; thereafter selectively removing the hydrophilic polymer; then selectively removing the resist film from a top of the substrate; thereafter applying a second block copolymer to the substrate; then phase-separating the second block copolymer into a hydrophilic polymer and a hydrophobic polymer; and thereafter selectively removing the hydrophilic polymer from the phase-separated second block copolymer. A ratio of a molecular weight of the hydrophilic polymer in the first block copolymer and the second block copolymer is 20% to 40%.
