Claim 12:
13. A method for processing wafers in a processing tool, comprising:
providing a hybrid model of a processing tool, wherein the hybrid model comprises:
a statistical model; and
a physical model, wherein the physical model is generated from a simulation of physical and chemical interactions within a processing tool across a plurality of different processing parameters;

executing a recipe in the processing tool to process a first wafer;
obtaining wafer data from the first wafer after execution of the recipe;
obtaining process data from the processing tool relating to the execution of the recipe;
providing the wafer data and the process data to the hybrid model to generate an updated hybrid model;
using the updated hybrid model to generate a modified recipe to account for chamber drift in the processing tool;
applying the modified recipe to a second wafer in the processing tool;
executing the recipe on a plurality of first wafers;
obtaining wafer data from the plurality of first wafers;
obtaining process data from the processing tool relating to the execution of the recipe on the plurality of first wafers; and
providing the wafer data and the process data from the processing of the plurality of first wafers to the hybrid model to generate an updated hybrid model.
