Coolant and a method to control the pH and resistivity of coolant used in a heat exchanger

Abstract:

Implementations described herein generally relate to substrate processing equipment and more particularly to methods and compositions for temperature control of substrate processing equipment. In one implementation, a method of cooling a processing chamber component is provided. The method comprises introducing an inert purge gas into a supply reservoir containing a coolant and flowing the treated coolant to a processing chamber component to cool the processing chamber component. The coolant initially comprises deionized water and a water-soluble base.
