    • A photoresist film removing apparatus includes a reacting chamber, an ozonizer producing a gas supplied to the reacting chamber, and an exhaust system that exhausts the gas from the reacting chamber. A source of a photoresist film-remover is located opposite a stage carrying a substrate covered with photoresist. Photoresist film-remover and the gas are supplied to the substrate through apertures. An electric field may be generated between the source of the photoresist film-remover and the substrate. Alternatively, a centrally located feed tube supplies only one of the gas and the photoresist film-remover through a single aperture and a reservoir discharges the other through apertures. The reservoir surrounds and is sealed to the feed tube. The apparatus may include a container holding a liquid photoresist film-remover and a mixture of the gas and remover is supplied from outside the reacting chamber to the substrate.
