Abstract
A method for operating a plasma reactor having a secondary chamber that is a neutral species source for the main chamber. The method in one embodiment of the invention consists of determining the desired increase in main chamber neutral particle density to be contributed by the secondary chamber for a given main chamber ion density range, and then to maintain the main chamber source power below a level beneath which the secondary chamber is capable of supplying the desired main chamber neutral density contribution.
