    摘要: A pattern-forming method includes forming a resist film on a substrate using a photoresist composition, exposing the resist film, and developing the exposed resist film using a negative developer that includes an organic solvent. The photoresist composition includes (A) a polymer that includes a structural unit (I) including an acid-labile group that dissociates due to an acid, the solubility of the polymer in the developer decreasing upon dissociation of the acid-labile group, and (B) a photoacid generator. The developer includes a nitrogen-containing compound.

    摘要: A radiation-sensitive resin composition includes an acid-labile group-containing polymer and photoacid generator. The radiation-sensitive resin composition is used to form a resist pattern using a developer that includes an organic solvent in an amount of 80 mass % or more. The radiation-sensitive resin composition has a contrast value γ of 5.0 to 30.0. The contrast value γ is calculated from a resist dissolution contrast curve obtained when developing the radiation-sensitive resin composition using the organic solvent.

    摘要: A radiation-sensitive resin composition includes a polymer, an acid-labile group-containing resin, a radiation-sensitive acid generator, and a solvent, the polymer including repeating units shown by following general formulas (1) and (2). wherein R1 and R2 represent a hydrogen atom, a methyl group, or a trifluoromethyl group, R3 represents a linear or branched alkyl group having 1 to 6 carbon atoms or an alicyclic hydrocarbon group having 4 to 20 carbon atoms in which at least one hydrogen atom is substituted with a fluorine atom, or a derivative thereof, and Z represents a group that includes a group that generates an acid upon exposure to light. The radiation-sensitive resin composition produces an excellent pattern shape, reduces the amount of elution into an immersion liquid upon contact during liquid immersion lithography, ensures that a high receding contact angle is formed by a resist film and an immersion liquid, and rarely causes development defects.
