Patent ID: 8016976

Claim:
A film removing device for removing an unnecessary part, formed on a peripheral part of a substrate having a corner, of a film of a coating solution formed on the substrate by spouting a solvent on the peripheral part of the substrate, said film removing device comprising: a support member that supports the substrate; an approach stage disposed near a first side surface of the substrate supported on the support member, the approach stage having a flat approach part having a surface flush with a surface of the substrate supported on the support member; a film removing unit provided with a spouting port through which the solvent is spouted toward the peripheral part of the substrate supported on the support member and a suction port through which a solution is sucked; a moving mechanism configured to move the film removing unit along a second side surface, continuous with the first side surface, of the substrate supported on the support member and the approach stage; and a gas spouting system configured to spout a gas into a gap formed between the flat approach part of the approach stage and the substrate supported on the support member; wherein the flat approach part faces the first side surface of the substrate supported on the support member at the corner where the first side surface and the second side surface join, and the gas spouting system has a spouting port opening in the side surface, facing the substrate, of the flat approach part, and a discharge passage having one end connected to the spouting port so that the gas spouting system spouts the gas into the gap formed between the side surface, facing the substrate, of the flat approach part and the first side surface, corresponding to the corner, of the substrate supported on the support member along the first side surface toward a side of the second side surface.
