Abstract:
1. A temperature control system comprising: a susceptor which allows an object to be processed to be held on a top surface thereof and comprises a flow path, through which a temperature adjusting medium flows, formed therein; a chiller which adjusts a temperature of the temperature adjusting medium flowing through the flow path; a sub-chiller which is disposed between the susceptor and the chiller, is separated from the chiller, and further adjusts a temperature of the temperature adjusting medium based on a temperature of the object held on the top surface of the susceptor; a forward flow path disposed between the chiller and the sub-chiller and between the sub-chiller and the susceptor, the temperature adjusting medium being supplied to the flow path of the susceptor from the chiller via the sub-chiller; and a return flow path disposed between the susceptor and the sub-chiller and between the sub-chiller and the chiller, the temperature adjusting medium being returned to the chiller via the sub-chiller from the flow path of the susceptor, wherein the temperature control system is configured to circulate the temperature adjusting medium between the chiller, the sub-chiller and the flow path through the forward flow path and the return flow path, and wherein the sub-chiller comprises: a first temperature adjuster which adjusts a temperature of the temperature adjusting medium flowing from the chiller via the sub-chiller to the susceptor through the forward flow path, and a second temperature adjuster which adjusts a temperature of the temperature adjusting medium flowing from the susceptor via the sub-chiller to the chiller through the return flow path.
