Claim 0:
1. A substrate processing apparatus for processing a substrate having a surface on which a first region and a second region, in which different substances are exposed, are present, the apparatus comprising:
a processing liquid supply unit which supplies a processing liquid to the surface of the substrate;
a processing film forming unit which solidifies or cures the processing liquid and forms a processing film on the surface of the substrate;
a preprocessing liquid supply unit which supplies a preprocessing liquid to the surface of the substrate;
a preprocessing film forming unit which solidifies or cures the preprocessing liquid and forms a preprocessing film on the surface of the substrate;
a stripping liquid supply unit which supplies a stripping liquid to the surface of the substrate; and
a controller which is configured to control the preprocessing liquid supply unit, the preprocessing film forming unit, the processing liquid supply unit, the processing film forming unit, and the stripping liquid supply unit,
wherein the controller is programmed to supply the preprocessing liquid from the preprocessing liquid supply unit toward the surface of the substrate, to solidify or cure the preprocessing liquid on the surface of the substrate by the preprocessing film forming unit to form the preprocessing film, which holds a removal target present on the surface of the substrate, on the surface of the substrate, to supply the stripping liquid from the stripping liquid supply unit to the surface of the substrate to separate the preprocessing film from the surface of the substrate in a state in which the preprocessing film holds the removal target, to supply the processing liquid from the processing liquid supply unit to the surface of the substrate after the preprocessing film is separated, to solidify or cure the processing liquid on the surface of the substrate by the processing film forming unit to form the processing film, which holds the removal target present on the surface of the substrate, on the surface of the substrate, and to supply the stripping liquid from the stripping liquid supply unit to the surface of the substrate to separate the processing film from the surface of the substrate in a state in which the processing film holds the removal target,
a removal capacity for the processing film to remove the removal target present in the second region is higher than a removal capacity for the preprocessing film to remove the removal target present in the second region, and
a removal capacity for the preprocessing film to remove the removal target present in the first region is higher than a removal capacity for the processing film to remove the removal target present in the first region.
