  • Publication number: 20140302256
    Abstract: Embodiments provide a plasma processing apparatus, substrate support assembly, and method of controlling a plasma process. The apparatus and substrate support assembly include a substrate support pedestal, a tuning assembly that includes a tuning electrode that is disposed in the pedestal and electrically coupled to a radio frequency (RF) tuner, and a heating assembly that includes one or more heating elements disposed within the pedestal for controlling a temperature profile of the substrate, where at least one of the heating elements is electrically coupled to an RF filter circuit that includes a first inductor configured in parallel with a formed capacitance of the first inductor to ground. The high impedance of the RF filters can be achieved by tuning the resonance of the RF filter circuit, which results in less RF leakage and better substrate processing results.

  • Publication number: 20140290576
    Abstract: Embodiments of the present invention relate to apparatus for improving uniformity and film stress of films deposited during plasma process of a substrate. According to embodiments, the apparatus includes a tuning electrode and/or a tuning ring electrically coupled to a variable capacitor for tuning high frequency RF impedance of the electrode and a low frequency RF termination to ground. The plasma profile and resulting film thickness can be controlled by adjusting the capacitance of the variable capacitor and the resulting impedance of the tuning electrode. The film stress of the film deposited on the substrate can be controlled, i.e., increased, by terminating the low frequency RF during processing.
