Abstract: A processing chamber and method of etching a semiconductor substrate are presented. The processing chamber is symmetric, with the centerlines of a chuck and stem of a stage to retain a semiconductor substrate aligned with a centerline of a passage in a core of a pump used to evacuate the processing chamber and with a centerline of a gas port through which gas is introduced to the processing chamber. The stem extends through the passage and a spiral groove is formed in the passage in only one of the stem or an inner surface of the core to provide pumping action to counter back streaming of the gas from an exhaust of the pump in an intermediate and viscous flow regime inside a gap between the stem and the core.
