    Abstract: Methods for cooling process chamber components are provided herein. In some embodiments, a method of cooling a process chamber component may include reducing a power provided to a heater disposed proximate a surface of the process chamber component to reduce an amount of heat provided to the component by the heater; providing a coolant to coolant channels disposed within the process chamber component using a pulsed flow having a duty cycle until the process chamber component reaches a temperature that is less than or equal to a predetermined magnitude above a temperature of the coolant; and after the process chamber component reaches the temperature less than or equal to the predetermined magnitude above a temperature of the coolant, reducing the duty cycle of the pulsed flow of the coolant to zero.

    Abstract: Components and systems for controlling a process or chamber component temperature as a plasma process is executed by plasma processing apparatus. A first heat transfer fluid channel is disposed in a component subjacent to a working surface disposed within a plasma processing chamber such that a first length of the first channel subjacent to a first temperature zone of the working surface comprises a different heat transfer coefficient, h, or heat transfer area, A, than a second length of the first channel subjacent to a second temperature zone of the working surface. In embodiments, different heat transfer coefficients or heat transfer areas are provided as a function of temperature zone to make more independent the temperature control of the first and second temperature zones.
