Abstract:
1. A plasma chamber comprising: a chamber; a first power supply; a second power supply; a gas supply and exhaust; an inductor on top of said chamber, said inductor coupled to said first power supply; an electrode inside said chamber, said electrode coupled to said second power supply; a first power controller coupled to said first power supply; a second power controller coupled to said second power supply; a pressure controller coupled to said gas supply and exhaust; and a computer coupled to said first power controller, said second power controller, said pressure controller, wherein said computer predictively calculates a surface profile to be created on a substrate by a plasma process sequence, wherein said computer tracks an energetic particle, wherein said computer records a plurality of ion fluxes from said energetic particle, wherein said computer solves simultaneously for a plurality of neutral fluxes, a surface chemical coverage, a surface material type, and wherein said computer computes a local etch rate and a local deposition rate from said plurality of ion fluxes, said plurality of neutral fluxes, said surface chemical coverage, said surface material type.
