Abstract:
The invention provides: a resin as a material of a composition for forming an organic film having high filling and planarizing properties and etching resistance; the composition; and a patterning process using the composition. Provided is a composition for forming an organic film, including: (I) a resin having a structure shown by a general formula (1) in which a ring structure AR containing an aromatic ring and a spiro structure SP bonded to four of the ARs are alternately repeated in at least a portion of a repeating unit; and (II) an organic solvent.
