ELECTRODE PHASING USING CONTROL PARAMETERS
A plasma processing system used for reactive sputtering may include multiple dual magnetron sputtering (DMS) components. Each DMS component may include a power supply coupled with two electrodes that switch between operation as a cathode and anode and are located within a plasma chamber. The power supply may be configured to operate as a transmitter or receiver power supply. A transmitter power supply may receive a phase-control-input signal that includes a phase offset value and may produce a phase-control-output signal and synchronization signal. The transmitter power supply may send the phase-control-output signal and synchronization signal to a receiver power supply, which may use these signals to synchronize electrode switching with the transmitter power supply and to apply the phase offset.
