Publication number: 20240212983Abstract: A plasma processing system is disclosed. A very high frequency (VHF) generator delivers power to a plasma chamber, and a mid-frequency (MF) generator delivers power to the plasma chamber. The VHF generator includes a sensor configured to provide a signal indicative of an impedance of a plasma load that is presented to the VHF generator. The VHF generator further includes a frequency tuner configured to adjust a frequency of the VHF generator within a cycle of the MF generator based on the signal to mitigate impedance modulation caused by the MF generator. Impedance modulation may also be mitigated by a sync line between the VHF and MF generators that allows presetting the VHF generator frequency in synchronization with a cycle of the MF generator.Type: ApplicationFiled: December 21, 2022Publication date: June 27, 2024Inventor: Masahiro Watanabe
