    摘要: A radiation-sensitive resin composition includes a polymer that includes at least one repeating unit (i) selected from a repeating unit shown by a formula (1), (2), and (3); and a repeating unit (ii) shown by a formula (4). R1 represents a hydrogen atom or a methyl group. Each R2 independently represents one of a linear or branched alkyl group having 1 to 12 carbon atoms, a linear or branched alkoxy group having 1 to 12 carbon atoms, and an alicyclic hydrocarbon group having 3 to 25 carbon atoms. p is an integer from 0 to 3, and q is an integer from 1 to 3, and p+q≦5. A chemically-amplified positive-tone resist film that is sensitive to extreme ultraviolet rays (EUV) can be formed using the radiation-sensitive resin composition.
