    摘要: A plasma reactor has a dual frequency plasma RF bias power supply furnishing RF bias power comprising first and second frequency components, f(1), f(2), respectively, and an RF power path having an input end coupled to the plasma RF bias power supply and an output end coupled to the wafer support pedestal, and sensor circuits providing measurement signals representing first and second frequency components of a measured voltage and first and second frequency components of a measured current near the input end of the RF power path. The reactor further includes a processor for providing first and second frequency components of a wafer voltage signal as, respectively, a first sum of the first frequency components of the measured voltage and measured current multiplied by first and second coefficients respectively, and a second sum of the second frequency components of the measured voltage and measured current multiplied by third and fourth coefficients, respectively. A processor produces a D.C. wafer voltage by combining D.C. components of the first and second frequency components of the wafer voltage with an intermodulation correction factor that is the product of the D.C. components of the first and second components of the wafer voltage raised to a selected power and multiplied by a selected coefficient.

    摘要: A method for processing a workpiece in a plasma reactor having a set of n coils includes constructing, for each one of the n coils, a set of plasma distributions for discrete values of coil current in a predetermined current range. The distributions are grouped, each group having one distribution for each of the n coils, and being a unique set of n distributions. A combined plasma distribution is computed from each group of distributions. The variance of each combined distribution is computed. The method further includes finding an optimum one of the combined distributions having an at least nearly minimum variance, and identifying the n coil currents associated with the optimum distribution. During plasma processing of the workpiece, currents through the coils are maintained at levels corresponding to the n coil currents associated with the one combined distribution.
