Claim 20:
21. A method, comprising:
generating a surface kinetics model output using a surface kinetics model, wherein the surface kinetics model is run based on an initial guess of one or more parameters of the surface kinetics model;
determining an expected response of the surface kinetics model output to excitation by polarized light using one or more additional parameters of the surface kinetics model, wherein the one or more additional parameters comprise one or more parameters not used during the initial guess of one or more parameters of the surface kinetics model;
comparing the determined expected response with one or more measurements of a sample received from a metrology tool;
generating one or more metrics based on the comparison between the determined expected response and the one or more measurements of the sample;
adjusting the one or more parameters of the surface kinetics model based on the one or more metrics to generate an adjusted surface kinetics model; and
applying the adjusted surface kinetics model to simulate on-sample performance during plasma processing of the sample; and
generating one or more control signals configured to selectively adjust one or more characteristics of one or more process tools based on the adjusted surface kinetics model.
