  • Patent number: 10025188
    Abstract: A resist pattern-forming method includes applying a resist underlayer film-forming composition to a substrate to form a resist underlayer film. The resist underlayer film-forming composition includes (A) a polysiloxane. A radiation-sensitive resin composition is applied to the resist underlayer film to form a resist film. The radiation-sensitive resin composition includes (a1) a polymer that changes in polarity and decreases in solubility in an organic solvent due to an acid. The resist film is exposed. The exposed resist film is developed using a developer that includes an organic solvent.
