A protective film forming composition which has a good mask (protection) function against a wet etching liquid and a high dry etching rate during processing of a semiconductor substrate and also has good coverage even for a stepped substrate, and from which a flat film can be formed due to a small difference in film thickness after being embedded; a protective film produced using the composition; a substrate with a resist pattern; and a method for producing a semiconductor device. This composition contains: (A) a compound having three or more carboxyl groups; (B) a resin or a monomer; and a solvent. The compound (A) having three or more carboxyl groups preferably has a ring structure. This ring structure is preferably selected from among an aromatic ring having 6-40 carbon atoms, an aliphatic ring having 3-10 carbon atoms, and a heterocyclic ring.
