Patent ID: 8110044

Claim:
A substrate processing apparatus comprising: a substrate processing part that has a temperature controlled object and applies a predetermined process to a substrate, the temperature controlled object being a part of an apparatus housing of said substrate processing part; a first flow passage that causes a first temperature control fluid to circulate, a part of the first flow passage passing through said substrate processing part, the first temperature control fluid for controlling a temperature of said temperature controlled object; a second flow passage that causes a second temperature control fluid to flow therethrough, the second temperature control fluid cooling said first temperature control fluid; a heat exchanger that causes a heat exchange between said first temperature control fluid and said second temperature control fluid, the heat exchanger being provided between the first flow passage and the second flow passage, distal to the substrate processing part and not in contact with the substrate processing part; and a flow amount control means for controlling an amount of flow of at least said second temperature control fluid.
