Abstract:
1. A resist pattern thickening material, comprising: a resin which is at least any one of a novolak resin and a polyparahydroxystyrene resin, a compound represented by the following General Formula (1), and a non-aqueous solvent, wherein the resist pattern thickening material is nonaqueous and contains no acid generator and no crosslinker, where “X” represents a functional group represented by the following Structural Formula (1); “Y” represents at least any one of a hydroxyl group, an amino group, an alkyl group-substituted amino group, an alkoxy group, an alkoxycarbonyl group, and an alkyl group, and the number of substituents in an amino group substituted by alkyl groups is an integer of 1 or 2; “m” is an integer of 1 or more; and “n” is an integer of 0 or more, where “R 1 ” and “R 2 ” may be same to each other or different from each other and respectively represent a hydrogen atom or a substituent group; “Z” represents at least any one of a hydroxyl group, an amino group, an alkyl group-substituted amino group, and an alkoxy group, and the number of substituents in an amino group substituted by alkyl groups is an integer of 1 or 2, wherein the non-aqueous solvent comprises any one of ethylene glycol and propylene glycol, wherein a content of the compound represented by the General Formula (1) in the resist pattern thickening material is 0.1 parts by mass to 10 parts by mass, and wherein the non-aqueous solvent comprises ethylene glycol, and a content of ethylene glycol in the non-aqueous solvent is 6% by mass to 63% by mass.
