| 摘要 |
A plasma reactor for processing a workpiece includes a reactor chamber and a workpiece support within the chamber, the chamber having a ceiling facing the workpiece support, an inductively coupled plasma source power applicator overlying the ceiling, and an RF power generator coupled to the inductively coupled source power applicator, and a capacitively coupled plasma source power applicator comprising a source power electrode at one of: (a) the ceiling (b) the workpiece support, and a VHF power generator coupled to the capacitively coupled source power applicator. The reactor further includes a plasma bias power applicator comprising a bias power electrode in the workpiece support and at least a first RF bias power generator coupled to the plasma bias power applicator, process gas distribution apparatus comprising a gas distribution showerhead in the ceiling, a vacuum pump for evacuating the chamber, and a first controller capable of adjusting the relative amounts of power simultaneously coupled to plasma in the chamber by the inductively coupled plasma source power applicator and the capacitively coupled plasma source power applicator.
