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 9):
A processing system comprising:\n the radio frequency control circuit of  claim 1 ; and a match network, wherein\n the controller comprises a first channel, a second channel and a third channel, \n the first channel outputs a third radio frequency signal, \n the second channel outputs a fourth radio frequency signal, \n the third channel outputs the first reference local oscillator signal to the first radio frequency sensor, \n the first radio frequency generator comprises a first power amplifier and a second power amplifier, \n the first power amplifier is configured to generate the first radio frequency signal based on the third radio frequency signal, \n the second power amplifier is configured to generate a fifth radio frequency signal based on the fourth radio frequency signal, and \n the match network is configured to receive the first radio frequency signal and the fifth radio frequency signal.
