Abstract
A semiconductor process system includes a semiconductor process chamber having an interior volume. A pump extracts gases from the semiconductor process chamber via an outlet channel communicably coupled to the semiconductor process chamber. The system includes a plurality of fluid nozzles configured to prevent the backflow of particles from the outlet channel to interior volume by generating a fluid barrier within the outlet channel responsive to the pump ceasing to function.
