    Abstract: Various implementations of the invention provide methods and apparatus for calibrating models of an optical lithographic process. In various implementations, a complete model of an optical lithographic process may be formed by combining different physical ranges and components describing the optical lithographic process. With various implementations of the invention, an optical lithographic process model may be calibrated by generating and applying a set of test patterns to the optical lithographic process, identifying test patterns and associated measured results that correspond to the discrete components of the optical lithographic model, calibrating the discrete components of the optical lithographic model based on the identified test patterns and measured results, and combining the calibrated components into a complete model. In some implementations of the invention, the discrete components of the optical lithographic model represent different physical effects of the optical lithographic process. Alternately or additionally, with various implementations of the invention the generated test patterns may include test structures sensitive to proximity effects, long-range pattern density, and long-range process non-uniformity.
