Abstract: A positive resist composition including a base component (A) which exhibits increased solubility in an alkali developing solution under action of acid and an acid-generator component (B) which generates acid upon exposure, the component (A) including a polymeric compound (A1) having an acid dissociable, dissolution inhibiting group in the structure thereof and including a structural unit (a0) having an —SO2— containing cyclic group on the terminal of the side chain, and the component (B) including an acid generator (B1) containing a compound represented by general formula (b1-1) (R0 represents a hydrocarbon group of 1 to 12 carbon atoms which may have a substituent, provided that the carbon atom adjacent to the sulfur atom within the —SO3? group has no fluorine atom bonded thereto, and Z+ represents an organic cation).

Abstract: A resist composition including: a base component (A) which exhibits changed solubility in an alkali developing solution under action of an acid; an acid generator component (B) which generates an acid upon exposure; and an organic solvent (S), wherein the base component (A) includes a polymeric compound (A1) which contains a structural unit (a0) represented by the general formula (a0-1) shown below: [Chemical Formula 1] (in the formula, R1 represents a hydrogen atom, a lower alkyl group, or a halogenated lower alkyl group; R2 represents a bivalent linking group; and R3 represents a cyclic group which has —SO2— within the ring skeleton), and the organic solvent (S) includes a cyclic ketone having a 5 to 7-membered ring or an ether represented by the general formula (S-1) shown below: [Chemical Formula 2] (in the formula, R4 represents an alkyl group of 1 to 5 carbon atoms; R5 represents an alkyl group of 1 to 3 carbon atoms; and n represents an integer of 0 to 2).
