Classification: CPC H  C | IPC C  H

Claim 0:
1. A non-transitory machine readable medium having instructions stored thereon, wherein the instructions are executable by one or more processors of a control system of a processing chamber to cause the control system to:
receive measurements indicative of a first pressure response in the processing chamber responsive to changing of at least one of a plurality of recipe parameters in accordance with a processing recipe being run on a first semiconductor substrate;
determine a first response error based on the first pressure response and a model pressure response calculated based on the processing recipe, wherein the model pressure response is generated as a feedforward control signal while running the processing recipe by a model that predicts a pressure in the chamber in response to changing the at least one of the plurality of recipe parameters; and
in response to determining that the first response error is greater than a threshold value, calculate an adjustment to an operation of a valve downstream of the processing chamber to be applied when changing the at least one of the plurality of recipe parameters in accordance with the processing recipe in a subsequent run of the processing recipe.
