Summary:A method for manufacturing a semiconductor substrate includes forming a resist underlayer film directly or indirectly on a substrate by applying a composition. The composition includes a compound and a solvent. The compound includes: at least one nitrogen-containing ring structure selected from the group consisting of a pyridine ring structure and a pyrimidine ring structure; and a partial structure represented by formula (1-1) or (1-2). X1 and X2 are each independently a group represented by formula (i), (ii), (iii), or (iv); * is a bond with a moiety of the compound other than the partial structure represented by formula (1-1) or (1-2); and Ar11 and Ar12 are each independently a substituted or unsubstituted aromatic ring having 5 to 20 ring members that forms a fused ring structure together with the two adjacent carbon atoms in the formulas (1-1) and (1-2).
