    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.

    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 form 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 polysiloxane composition includes a polysiloxane, and a first compound. The first compound includes a nitrogen-containing heterocyclic ring structure, and a polar group, an ester group or a combination thereof. A pattern-forming method includes coating the polysiloxane composition on a substrate to be processed to provide a silicon-containing film. A resist composition is coated on the silicon-containing film to provide a resist coating film. The resist coating film is selectively irradiated with a radioactive ray through a photomask to expose the resist coating film. The exposed resist coating film is developed to form a resist pattern. The silicon-containing film and the substrate to be processed are sequentially dry etched using the resist pattern as a mask.
