Claim 7:
8. A system comprising:
one or more processors; and
one or more memory devices comprising instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
accessing a plurality of input parameters for a processing chamber, wherein the plurality of input parameters are in part derived from a recipe for the processing chamber to perform a process on a substrate;
providing the plurality of input parameters for the processing chamber to a model, wherein the model has been trained using previous pluralities of input parameters and corresponding pluralities of sensor measurements;
receiving one or more first outputs from the model that indicate a predicted first amount of RF power that will be reflected back from the processing chamber to an RF source when igniting a plasma in the processing chamber; and
adjusting the plurality of input parameters based on the predicted first amount of RF power that is reflected back from the processing chamber.
