Abstract:
A RF control circuit is provided and includes a controller, a divider, and a RF sensor. The controller selects a RF, which is a frequency of a reference LO signal. The divider receives a first RF signal detected in a substrate processing chamber and outputs a second RF signal. The first RF signal is generated by a RF generator and supplied to the substrate processing chamber. The RF sensor includes a lock-in amplifier, which includes: a RF path that receives the second RF signal; a LO path that receives the reference LO signal; a first mixer that generates an IF signal based on the second RF signal and the reference LO signal; and a filter that filters the IF signal. The controller generates a control signal based on the filtered IF signal and transmits the control signal to the RF generator to adjust the first RF signal.

Claim (Index 10):
A processing system comprising:\n the radio frequency control circuit of  claim 1 ; and a match network configured to receive the first radio frequency signal, wherein\n the first radio frequency generator comprises a first channel and a second channel, \n the first radio frequency signal is generated based on an output of the first channel, \n the second channel is configured to output the first reference local oscillator signal, \n the first radio frequency sensor comprises\n a second mixer configured to generate a second intermediate frequency signal based on an output of the match network, wherein the first mixer is configured to generate the first intermediate frequency signal based on the first reference local oscillator signal, and \n a phase shifter configured to phase shift the first reference local oscillator signal, \n \n the second mixer is configured to generate the second intermediate frequency signal based on the phase shifted first reference local oscillator signal, \n an output of the first radio frequency sensor is generated based on the second intermediate frequency signal, and \n the controller is configured to generate the control signal to control the first radio frequency generator based on the output of the first radio frequency sensor.
