A method and apparatus for delivering precursor materials to a processing chamber is described. The apparatus includes a gas distribution assembly having multiple gas delivery zones. Each zone may include a plenum having an inlet for receiving a precursor gas and at least one source of non-thermal energy, such as an infrared light source. The at least one source of non-thermal energy is may be varied to control the intensity of wavelengths from the infrared light source.

Abstract:
In one embodiment, a gas distribution assembly includes an injection block having at least one inlet to deliver a precursor gas to a plurality of plenums from at least two gas sources, a perforated plate bounding at least one side of each of the plurality of plenums, at least one radiant energy source positioned within each of the plurality of plenums to provide energy to the precursor gas from one or both of the at least two gas sources and flow an energized gas though openings in the perforated plate and into a chamber, and a variable power source coupled to each of the radiant energy sources positioned within each of the plurality of plenums.
