Actinic ray- or radiation-sensitive resin composition, actinic ray- or radiation-sensitive film and method of forming pattern

Abstract

According to one embodiment, there is provided an actinic ray- or radiation-sensitive resin composition containing (A) a resin containing a repeating unit represented by general formula (1) below and a repeating unit that is decomposed by an action of an acid to generate an alkali-soluble group, and (B) a compound that generates the acid when exposed to actinic rays or radiation, where L represents a bivalent connecting group, R1 represents a hydrogen atom or an alkyl group, and Z represents a cyclic acid anhydride structure.

Dependencies are inferred from the claim text.
