DUAL-PHASE COOLING IN SEMICONDUCTOR MANUFACTURING

Abstract:

In some examples, a substrate processing system comprises a processing chamber, a dual-phase cooling system, and a back-pressure regulator which regulates the pressure of the dual-phase coolant. The dual-phase cooling system regulates the temperature of the processing chamber or a first component thereof. The dual-phase cooling system includes a cooling loop in thermal communication with the processing chamber or the component. The cooling loop contains a dual-phase coolant in fluid communication with a heat exchanger. The processing chamber or the first component includes a top plate or a cool plate comprising one or more e passageways forming part of the cooling loop.
