Abstract:
1. A temperature control system that controls temperatures of a plurality of members of a substrate processing apparatus, comprising: a circulation system that accommodates a first coolant to pass through the inside of each of at least a part of the members; a heat exchange unit consisting essentially of a heat exchanger that performs heat exchange between the first coolant of the circulation system and a second coolant and a pump that circulates the first coolant in the circulation system; and a chiller that supplies the second coolant to the heat exchanger, wherein the circulation system includes one or more branch lines for each of said at least the part of the members passing through the inside thereof, wherein each of the branch lines is provided with a heating member that heats the first coolant supplied thereto, wherein the heat exchanger is installed in a room where the substrate processing apparatus is installed, wherein the temperature control system is configured to control temperatures of said at least the part of the members to be different from each other by using the heating member, wherein the heating member is provided on an inlet side of each of said at least the part of the members, wherein a flow rate control valve is installed at each of the branch lines, on an inlet side of the heating member, and wherein the first coolant is cooled in the heat exchanger to a temperature below target temperatures of said at least the part of the members and heated by the heating member to a respective target temperature.
