Claim:
1. A substrate processing apparatus comprising: a processing liquid supplying unit arranged to supply processing liquid onto an upper surface of a substrate to form a liquid film of the processing liquid; a substrate heating unit arranged to heat the substrate from below the substrate to heat the liquid film on the substrate and arranged to be in contact with a lower surface of the substrate to support the substrate thereon; and an attitude changing unit arranged to cause the substrate and the substrate heating unit to undergo an attitude change between a horizontal attitude in which the upper surface of the substrate is horizontal so that the liquid film of the processing liquid is held on the substrate, and a tilted attitude in which the upper surface of the substrate is tilted so that the liquid film of the processing liquid heated by the substrate heating unit is removed from the substrate, while keeping constant a relative attitude between the substrate and the substrate heating unit, wherein the attitude changing unit is arranged to cause the substrate heating unit, which is supporting the substrate thereon, to undergo the attitude change between the horizontal attitude and the tilted attitude, and the substrate processing apparatus further comprises a sliding preventing member arranged to come into contact with a lower portion of a peripheral portion of the substrate tilted at the tilted attitude to prevent the substrate from sliding off the substrate heating unit.
