    Abstract: A pattern-forming method comprises forming a prepattern that is insoluble or hardly soluble in an organic solvent. A first composition is applied on at least lateral faces of the prepattern to fort i a resin layer.Adjacent regions to the prepattern of the resin layer are insolubilized or desolubilized in the organic solvent without being accompanied by an increase in a molecular weight by heating the prepattern and the resin layer. Regions other than the adjacent regions insolubilized or desolubilized of the resin layer are removed with the organic solvent. The first composition comprises a first polymer having a solubility in the organic solvent to be decreased by an action of an acid. At least one selected from the following features (i) and (ii) is satisfied: (i) the first polymer comprises a basic group; and (ii) the first composition further comprises a basic compound.

    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.
