Abstract: In an apparatus and a method of forming a photoresist pattern, a photoresist-coating section coats a substrate with a photoresist composition to form a photoresist film. A light is irradiated onto the photoresist film by using an exposure section, and a developing section develops the photoresist film.

Therefore, the residue is effectively removed by spraying the solvent in the region of the residue and absorbing the residue dissolved by the solvent.
