Abstract:
1. A method of treating a dielectric film on a plurality of substrates, comprising: disposing said plurality of substrates in a substrate holder of a batch processing system, said dielectric film having a dielectric constant value less than the dielectric constant of SiO disposing said substrate holder on a turntable configured to rotate during an exposure of at least one surface of said dielectric film on said plurality of substrates to a treating compound, said plurality of substrates being arranged in a tier arrangement on the substrate holder, the treating compound including a C heating said plurality of substrates; exciting the treating compound to dissociate the treating compound in a plasma; removing moisture from the at least one surface of the dielectric film by exposing the at least one surface of said dielectric film on said plurality of substrates to the treating compound, wherein the at least one surface of the plurality of substrates is exposed to the treating compound supplied to the processing system by independently controlling multiple gas injection devices to inject the treating compound at different vertical regions of the processing system along the tier arrangement of substrates on the substrate holder.
