Abstract
A control system is provided and includes a memory and a conversion module. The memory is configured to store position data of first positions of a first variable capacitor of a first match network of a first plasma processing system. Each of the first positions of the first variable capacitor corresponds to a respective one of multiple loads experienced by the first match network. The conversion module is configured to: obtain the position data stored in the memory; determine reference capacitor positions based on the position data; determine a calibrated conversion model based on the reference capacitor positions, where the calibrated conversion model converts second positions of the first variable capacitor to comparable capacitor positions, and where the second positions are positions of the first variable capacitor existing subsequent to the determination of the calibrated conversion model; and store the calibrated conversion model.
