摘要： A method of cleaning a semiconductor fabrication processing chamber involves recirculation of cleaning gas components. Consequently, input cleaning gas is utilized efficiently, and undesirable emissions are reduced. The method includes flowing a cleaning gas to an inlet of a processing chamber, and exposing surfaces of the processing chamber to the cleaning gas to clean the surfaces, thereby producing a reaction product. The method further includes removing an outlet gas including the reaction product from an outlet of the processing chamber, separating at least a portion of the reaction product from the outlet gas, and recirculating a portion of the outlet gas to the inlet of the processing chamber.
