Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition, comprising: (A) a resin capable of increasing its solubility in an alkaline developer by the action of an acid; and (C) at least one selected from the group of compounds represented by the following formula (ZI-3), (ZI-4) or (ZI-5) and capable of generating an acid upon irradiation of actinic rays or radiation, wherein the resin (A) contains at least one repeating unit (a) having a group capable of decomposing by the action of an acid to leave a leaving group having a ring structure, the leaving group having a ring structure has at least one of a polar group as a substituent and a polar atom as a part of the ring structure, and a compound derived from the leaving group having a ring structure has a logP value of not less than 0 and less than 2.8 and the repeating unit (a) is represented by formula (I): wherein in formula (ZI-3), X R R represents a substituent, n Z wherein in formula (ZI-4), R R R R Z wherein in formula (ZI-5), X represents an oxygen atom, a sulfur atom or —N(Rx)- wherein Rx represents a hydrogen atom, an alkyl group, a cycloalkyl group, an acyl group, an alkenyl group, an alkoxycarbonyl group, an aryl group, an arylcarbonyl group or an aryloxycarbonyl group, R R R Z wherein formula (I), R R R W represents an alkylene group or a cycloalkylene group, X represents an oxygen atom or a sulfur atom, and the X-containing ring represents a ring structure containing an ether bond or a thioether bond, and l and n each independently represents an integer of 0 or more, and in a case where n is 2 or more, each of a plurality of R
