    Abstract: A photoresist composition includes a polymer that includes a first structural unit shown by a formula (1), and an acid generator. R1 represents a hydrogen atom, a fluorine atom, a methyl group, or a trifluoromethyl group. R2 represents a divalent hydrocarbon group having 1 to 10 carbon atoms. A represents —COO—*, —OCO—*, —O—, —S—, or —NH—, wherein “*” indicates a site bonded to R3. R3 represents a single bond or a divalent hydrocarbon group having 1 to 10 carbon atoms. The polymer preferably further includes a second structural unit that includes an acid-labile group.

    Abstract: A radiation-sensitive resin composition for forming a resist film includes a polymer including a first structural unit represented by a formula (1) and a second structural unit represented by a formula (2). The first structural unit and the second structural unit are included in an identical polymer molecule or different polymer molecules. R1 represents a hydrogen atom or a methyl group. Q represents a divalent linking group having 1 to 4 carbon atoms. X represents a monovalent lactone group. A part or all of hydrogen atoms included in the monovalent lactone group represented by X are not substituted or substituted. R2 represents a hydrogen atom or a methyl group. Y represents a monovalent lactone group. A part or all of hydrogen atoms included in the monovalent lactone group represented by Y are not substituted or substituted.
