The present invention provides a method for producing a composition for forming an organic film, the composition being used in a process of manufacturing a semiconductor apparatus, the method including the steps of (1) washing a compound having an aromatic skeleton by an acid, (2) preparing a composition solution containing the washed compound, (3) filtering the prepared composition solution through a filter, and (4) putting the filtered composition solution into a container made of an organic resin. There can be provided a method for producing a composition for forming an organic film that can form an organic film in which defects after dry etching are reduced. |
