Abstract
A method of reducing reflected Radio Frequency (RF) power in substrate processing chambers may include accessing input parameters for a processing chamber that are derived from a recipe to perform a process on a substrate. The input parameters may be provided to a model that has been trained using previous input parameters and corresponding sensor measurements for the chamber. A predicted amount of reflected RF power may be received from the model and it may be determined whether the predicted reflected RF power is optimized. The input parameters may be repeatedly adjusted and processed by the model until input parameter values are found that optimize the reflected RF power. Optimized input parameters may then be provided to the chamber to process the substrate.
