Abstract:
1. A radiation-sensitive resin composition comprising: a first polymer including a repeating unit represented by a formula (I); and an acid generating component including a second polymer which includes a repeating unit represented by a formula (3), a radiation-sensitive acid generator other than the first polymer or the second polymer, or both thereof, the acid generating component generating an acid upon irradiation with actinic radiation or a radioactive ray, the first polymer serving as a base with respect to the acid where the radiation-sensitive resin composition is not irradiated with the actinic radiation or the radioactive ray, wherein R R R R A X “a” is 0 or 1, wherein an end of R wherein, each of R 1 , R 2 and X + is respectively as defined in the formula (I), and n is an integer of 1 to 4, wherein the first polymer, the second polymer, or both thereof further includes a repeating unit represented by a formula (2), wherein R R R
