| 摘要 |
A method and apparatus for generating a complex waveform and coupling the waveform to a reaction chamber of a semiconductor wafer processing system using a power amplifier. Specifically, the apparatus includes a complex waveform generator coupled to a high-power amplifier. The high-power amplifier is coupled to one or more frequency selective matching networks which select bands of RF signal to be coupled to plasma excitation circuit within the semiconductor wafer processing system.
