Abstract
A composition includes: a compound including an aromatic hydrocarbon ring structure, and a partial structure represented by formula (1) which bonds to the aromatic hydrocarbon ring structure; and a solvent. The aromatic hydrocarbon ring structure has no fewer than 25 carbon atoms. In the formula (1), X represents a group represented by formula (i), (ii), (iii), or (iv); and *'s denote binding sites to two adjacent carbon atoms constituting the aromatic hydrocarbon ring structure. A method of producing a patterned substrate, includes applying the composition directly or indirectly on a substrate to form a resist underlayer film; forming a resist pattern directly or indirectly on the resist underlayer film; and carrying out etching using the resist pattern as a mask.
