Abstract: Methods and systems for controlling temperatures in plasma processing chamber via pulsed application of heating power and pulsed application of cooling power. In an embodiment, fluid levels in each of a hot and cold reservoir coupled to the temperature controlled component are maintained in part by a coupling each of the reservoirs to a common secondary reservoir.

Abstract: Provided is a capacitively coupled plasma processing apparatus which improves a controllability of the RF bias function and reliably prevents unwanted resonance from being generated on a RF transmission line between a counter electrode and ground potential to enhance reliability of the plasma process. In the capacitive coupled type plasma processing apparatus, three kinds of RF powers from a first, second and third RF power supplies (35, 36, 38) are superimposed and applied to susceptor (lower electrode) (16). In such a three-frequency superimposing and applying application scheme, the frequency-impedance characteristic around upper electrode (48) is considered to prevent a serial resonance from occurring on an RF transmission line around upper electrode (48) in consideration of all the low order frequencies of the IMD relevant to and affecting the plasma process.
