    Abstract: Embodiments described herein relate to plasma processes. A tool includes a pedestal. The pedestal is configured to support a semiconductor substrate. The tool includes a bias source. The bias source is electrically coupled to the pedestal. The bias source is operable to bias the pedestal with a direct current (DC) voltage. The tool includes a plasma generator. The plasma generator is operable to generate a plasma remote from the pedestal. A method for semiconductor processing includes performing a plasma process on a substrate in a tool. The plasma process includes flowing a gas into the tool. The plasma process includes biasing a pedestal that supports the substrate in the tool. The plasma process includes igniting a plasma in the tool using the gas.
