Claim 15:
16. A method using a semiconductor processing chamber, wherein the semiconductor processing chamber includes:
a resonator housing positioned on the semiconductor processing chamber, the resonator housing having a radio frequency (RF) coil disposed within the resonator housing,
an RF power source connected to the semiconductor processing chamber for applying RF power to the RF coil, and
a plurality of jigs disposed about the resonator housing and attached to the semiconductor processing chamber via pre-existing holes in the semiconductor processing chamber,
the method comprising:
recording a first position of the resonator housing using the plurality of jigs;
performing a pre-clean operation on a semiconductor wafer positioned in the semiconductor processing chamber;
removing the semiconductor wafer from the semiconductor processing chamber;
recording a second position of the resonator housing using the plurality of jigs;
determining a shift in a position of the resonator housing from the first position using the plurality of jigs; and
adjusting one or more of the plurality of jigs to relocate the resonator housing back to the first position.
