Abstract:
1. A radiation-sensitive resin composition comprising: a first polymer including an acid-labile group; an acid generator to generate an acid upon exposure to radiation; and a second polymer including a fluorine atom and a repeating unit shown by a general formula (c1), the second polymer having a fluorine atom content higher than a fluorine atom content of the first polymer, wherein n is an integer from 1 to 3, R A represents an oxygen atom or —CO—O— R X R E represents an oxygen atom, —CO—O— R represents a hydrogen atom, a methyl group, or a trifluoromethyl group, and in a case where A represents —CO—O— wherein R 10 represents a halogen atom, an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, an acyl group having 1 to 10 carbon atoms, or an acyloxy group having 1 to 10 carbon atoms, whrein each R 10 is either a same as or different from each other when a plurality of R 10 are present, m m each of R wherein the second polymer further includes a repeating unit shown by a general formula (c3) or a repeating unit shown by a general formula (c4), wherein R is a same as defined for the general formula (c1), G represents a single bond, an oxygen atom, a sulfur atom, —CO—O—, —SO R wherein m is an integer from 1 to 3, R is a same as defined for the general formula (c1), wherein each R is either a same as or different from each other when m is 2 or 3, A is a same as defined for the general formula (c1), wherein each A is either a same as or different from each other when m is 2 or 3, R R R X
