Abstract

The present invention provides: a composition for forming a resist underlayer film that enables formation of a desired resist pattern; and a method for producing a resist pattern and a method for producing a semiconductor device, which each use said resist underlayer film-forming composition. This resist underlayer film-forming composition contains a reaction product obtained from: a compound (A) that is dissolved in a solvent and that is represented by formula (1) (in formula (1), A represents an organic group including an aliphatic ring, an aromatic ring, or a heterocyclic ring); a compound (B) having two functional groups that are reactive with respect to an epoxy group; and a compound (C) having one functional group that is reactive with respect to an epoxy group.
