Zusammenfassung: | A technology to control temperature of a large substrate to be heated. A temperature sensing device is disposed lateral to a region where a radiation heater faces a substrate to be heated inside a heating chamber. A heating device has the heating chamber, the radiation heater, a power-supply device, a substrate-holding device, a control device, and the temperature sensing device. A control program is built into the control device, according to which the power-supply device controls the power applied to the radiation heater to generate heat such that the temperature of the temperature measurement substrate detected by a thermocouple of the temperature sensing device becomes a set temperature. Furthermore, a circulation passage is disposed in close contact with the temperature-sensing device, and with a coolant flowing through the circulation passage, the temperature of the temperature measurement substrate can be cooled from the set temperature to an initial temperature. |
