A processing chamber including a reaction chamber having a processing area, a processing gas inlet in communication with the processing area, a first excited species generation zone in communication with the processing gas inlet and a second exited species generation zone in communication with the processing gas inlet. A method of processing a substrate including the steps of loading a substrate within a processing area, activating a first excited species generation zone to provide a first excited species precursor to the processing area during a first pulse and, activating a second excited species generation zone to provide a second excited species precursor different from the first excited species precursor to the processing area during a second pulse.
