Claim:
1. A nontransitory computer readable storage medium with computer instructions which when executed causes a computer to perform: using at least one computer processor, building a process window capable optical proximity correction compact model based on empirical data obtained from only a first process combination of a focus-exposure matrix of a photolithographic process, and using the process window capable optical proximity correction compact model to extrapolate process combinations different from the first process combination in the focus-exposure matrix, building a non-optical part of the process window capable optical proximity correction compact model, and an optical part of the process window capable optical proximity correction compact model, and using at least the optical part of the process window capable optical proximity correction model and the non-optical part of the process window capable optical proximity correction model, predicting critical dimension data of the photolithographic process at a second process combination of the focus-exposure matrix of the photolithographic process, wherein the second process combination and the first process combination are different in at least one of a dose and a defocus.
