Abstract:
1. A photosensitive composition for exposure with an ArF excimer laser comprising: (A) a compound capable of generating a compound represented by formula (I) upon irradiation with actinic rays or radiation: wherein X represents —CO— or —SO R represents a fluorine atom-containing divalent linking group; A represents an acidic group; and (C) a resin having a group capable of decomposing under the action of an acid to increase a solubility of resin (C) in alkali developer; wherein the compound (A) capable of generating a compound represented by formula (I) upon irradiation with actinic rays or radiation is a sulfonium salt compound of the compound represented by formula (I) or an iodonium salt compound of the compound represented by formula (I); the acidic group of A in formula (I) is —SO
