Claim 16:
17. A substrate processing apparatus, comprising:
a substrate holding mechanism including a gripper configured to hold a substrate horizontally;
a processing liquid supply configured to discharge a processing liquid toward the substrate held by the substrate holding mechanism;
a first temperature sensor configured to detect a temperature of a central portion of the substrate held by the substrate holding mechanism;
a second temperature sensor configured to detect a temperature of an edge portion of the substrate held by the substrate holding mechanism; and
a controller,
wherein the controller controls the substrate holding mechanism, the processing liquid supply, the first temperature sensor, and the second temperature sensor to perform a substrate processing method comprising:
performing a liquid processing on the substrate by discharging the processing liquid onto the substrate from the processing liquid supply in a state that the substrate is held by the gripper of the substrate holding mechanism horizontally;
detecting the temperature of the central portion of the substrate and the temperature of the edge portion of the substrate in the liquid processing by using the first temperature sensor and the second temperature sensor, respectively;
generating temperature distribution information indicating an in-surface temperature distribution of the substrate in the liquid processing based on one or more parameter values defining a processing condition for the liquid processing and the temperature of the central portion of the substrate and the temperature of the edge portion of the substrate detected in the detecting of the temperature; and
determining, based on the temperature distribution information, whether a result of the liquid processing is good or bad,
wherein, in the detecting of the temperature, a temperature detected by at least one of the multiple sensors provided at the griper of the substrate holding mechanism is detected as the temperature of the edge portion of the substrate.
