Abstract:
Multiple harmonic frequency components are used for plasma excitation in a plasma process. Relative amplitude and/or phase shift between the different frequency components is controlled so as to provide desired ion energy plasma properties. The relative amplitude and/or phase shift may be controlled without direct and/or manual ion energy measurements. Rather, the ion energy within the plasma may be dynamically controlled by monitoring one or more electrical characteristics within the plasma apparatus, such as for example, impedance levels, electrical signals in the radio frequency (RF) generator, electrical signals in a the matching networks, and electrical signals in other circuits of the plasma processing apparatus. The monitoring and control of the ion energy may be accomplished dynamically during the plasma process so as to maintain a desired ion energy distribution.

Claim (Index 1):
A plasma processing system capable of plasma processing a substrate, comprising:\n a process chamber; one or more RF sources, the one or more RF sources coupled to the process chamber and configured to provide RF power to the process chamber through at least a base frequency voltage at a base frequency and a second frequency voltage at a second frequency, the second frequency being a second harmonic frequency or higher harmonic of the base frequency; control circuitry, the control circuitry coupled to at least one other component of the plasma processing system to receive at least one electrical characteristic of the plasma processing system during plasma processing of the substrate; and at least one output of the control circuitry coupled to the at least one of the one or more RF sources, the one or more RF sources configured to adjust a characteristic of the base frequency voltage and/or the second frequency voltage so as to be capable of obtaining a desired ion energy distribution during plasma processing of the substrate.
