Abstract:
1. A microwave irradiation apparatus that processes a target object by irradiating microwave, the apparatus comprising: a processing chamber configured to be vacuum-evacuated; a supporting table configured to support the target object; a processing gas introduction unit configured to introduce a processing gas into the processing chamber; a microwave introduction unit configured to directly irradiate the microwave to an upper surface of the target object and heat the target object; a gas cooling unit configured to cool the target object by a cooling gas; a radiation thermometer configured to measure a temperature of the target object heated by the microwave; and a temperature control unit configured to adjust the temperature of the target object by controlling the gas cooling unit based on the temperature measured by the radiation thermometer, wherein the gas cooling unit includes a shower head provided above the supporting table, and the shower head is configured to discharge the cooling gas toward the upper surface of the target object to cool the target object.
