  • Publication number: 20190264035
    Abstract: A substrate-treating method includes applying a treatment agent directly or indirectly on one face of a substrate to form a substrate pattern collapse-inhibitory film. The substrate includes a pattern on the one face. The substrate pattern collapse-inhibitory film is removed by dry etching after forming the substrate pattern collapse-inhibitory film. The treatment agent includes a compound including an aromatic ring, and a hetero atom-containing group that bonds to the aromatic ring; and a solvent.
