Abstract:
1. A method of processing substrates, comprising: introducing a first gas into a processing volume of a processing chamber through a first gas inlet coupled to a first gas channel of a showerhead assembly; introducing a second gas into the processing volume of the processing chamber through a second gas inlet coupled to a second gas channel of the showerhead assembly, wherein the first gas channel is isolated from the second gas channel, wherein the first gas is delivered into the processing volume through a plurality of first gas conduits and the second gas is delivered into the processing volume through a plurality of second gas conduits; cooling the showerhead assembly by flowing a heat exchanging fluid through a temperature control channel disposed in the showerhead assembly, wherein the plurality of first and second gas conduits are disposed through the heat exchanging channel; and introducing a cleaning gas into the processing volume of the processing chamber through a cleaning gas conduit directly coupling a cleaning gas inlet with the processing volume of the processing chamber, wherein the cleaning gas conduit extends through and is isolated from the first gas channel, the second gas channel, and the temperature control channel.
