Abstract:
1. A substrate processing apparatus that dries a substrate by supplying a volatile processing liquid after a liquid processing of the substrate with a processing liquid, the apparatus comprising: a processing liquid supply unit configured to supply a processing liquid to the substrate; a volatile processing liquid supply unit configured to supply a volatile processing liquid onto the substrate; a substrate heating unit configured to heat the substrate; and a controller configured to control the volatile processing liquid supply unit and the substrate heating unit, wherein the controller executes a process of supplying the processing liquid from the processing liquid supply unit to the substrate to process the substrate, a process of heating the substrate on which a liquid film of the processing liquid is formed by the substrate heating unit, a process of supplying a volatile processing liquid from the volatile processing liquid supply unit to the substrate on which the liquid film of the processing liquid is formed, a process of stopping the supply of the volatile processing liquid to the substrate from the volatile processing liquid supply unit, and a process of drying the substrate by removing the volatile processing liquid, and wherein the process of heating the substrate starts before the process of supplying the volatile processing liquid, and the substrate heating unit heats the substrate so that the surface temperature of the substrate is higher than a dew point before the surface of the substrate is exposed from the volatile processing liquid.
