Abstract:
A radiation-sensitive resin composition includes a compound represented by a formula (1), and a base polymer. A represents —CO— or —CH2—. R1 represents a hydrocarbon group having 1 to 30 carbon atoms, a heterocyclic group having 3 to 30 ring atoms, or a combination of a first group and a second group. The first group is —CO—, —COO—, —OCO—, —O—CO—O—, —NHCO—, —CONH—, —NH—CO—O—, —O—CO—NH—, —NH—, —S—, —SO—, —SO2—, —SO2—O— or a combination thereof, and the second group is a hydrocarbon group having 1 to 30 carbon atoms, a heterocyclic group having 3 to 30 ring atoms or a combination thereof. A part or all of hydrogen atoms included in the hydrocarbon group and the heterocyclic group are not substituted or substituted. M+ represents a monovalent cation.
