Independent radiant gas preheating for precursor disassociation control and gas reaction kinetics in low temperature CVD systems
A method and apparatus for delivering precursor materials to a processing chamber is provided. In one embodiment, a deposition apparatus is provided. The apparatus includes a chamber having a longitudinal axis, and a gas distribution assembly coupled to a sidewall of the chamber. The gas distribution assembly comprises a plurality of plenums coupled to one or more gas sources, an energy source positioned to provide energy to each of the plurality of plenums, and a variable power source coupled to the energy source, wherein the gas distribution assembly provides a flow path through the chamber that is normal to the longitudinal axis of the chamber.
