  • Patent number: 10032608
    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.

  • Publication number: 20170084448
    Abstract: Embodiments described herein generally relate to methods for forming a conformal silicon nitride layer at low temperatures. The conformal silicon nitride layer may be formed by pulsing a radio frequency (RF) power into a processing chamber while a gas mixture including trisilylamine is flowing into the processing chamber. Pulsed RF power increases the ratio of neutral to ionic species and activated species of trisilylamine have low sticking coefficients and greater surface migration. As a result, conformality of the deposited silicon nitride layer is improved.
