Abstract:
1. A heat treatment apparatus that increases or decreases a temperature of a processing object to a setting temperature, the heat treatment apparatus comprising: a processing chamber which accommodates the processing object; a heating unit which heats the processing object accommodated in the processing chamber; a memory unit which stores two or more temperature control models that are previously created; a temperature controller which controls a temperature of the heating unit; and an apparatus controller which controls the temperature controller and the memory unit, wherein the apparatus controller is configured: to select, among the stored two or more temperature control models, a first temperature control model capable of increasing or decreasing the temperature of the processing object more rapidly than other stored temperature control models, and, in the middle of temperature increase or temperature decrease of the processing object, to switch the selected temperature control model to a second temperature control model among the stored two or more temperature control models, the second temperature control model being capable of more stably converging the temperature of the processing object to the setting temperature than other stored temperature control models, and wherein the temperature controller reads out the selected temperature control model from the memory unit to control the heating unit.
