Claim 5:
6. The substrate processing method of claim 1, further comprising:
heating the substrate in the partially etching of the metal polycrystalline film to the washing away of the etching residue generated in the etching of the remaining portion of the metal polycrystalline film,
wherein the heating of the substrate includes heating the substrate such that a temperature of the substrate before and after the start of the supplying of the rinse liquid in the washing away of the etching residue generated in the etching of the remaining portion of the metal polycrystalline film becomes lower than the temperature of the substrate during the supplying of the etching liquid in the partially etching of the metal polycrystalline film and in the etching of the remaining portion of the metal polycrystalline film.
