摘要： Methods and systems for controlling temperatures in plasma processing chamber for a wide range of setpoint temperatures and reduced energy consumption. Temperature control is coordinated between a coolant liquid loop and a heat source by a control algorithm implemented by the plasma processing module controller. The control algorithm may completely stop the flow of coolant liquid to a temperature-controlled component in response to a feedback signal indicating an actual temperature is below the setpoint temperature. The control algorithm may further be based at least in part on a feedforward control signal derived from a plasma power or change in plasma power input into the processing chamber during process recipe execution.

摘要： Methods and apparatus for tuning matching networks are provided herein. A method of tuning a matching network includes providing a matching network coupling an RF source to a load, the matching network having a tunable element disposed at a first set point; increasing a value of the tunable element by a first step above the first set point; sensing a first adjusted value of a reflected RF power; decreasing the value of the tunable element by the first step below the first set point; sensing a second adjusted value of the reflected RF power; comparing the first and the second adjusted values of the reflected RF power; and moving the tunable element to a second set point that corresponds to a position having a lowest adjusted value of the reflected RF power. The method may be repeated until the reflected RF power falls within an acceptable reflected RF power range.
