Systems and methods of modeling a best-guess semiconductor process flow for fabricating a desired semiconductor device are provided. The best-guess process flow is modeled using an inverse modeling technique. This technique reverse engineers a desired semiconductor device to synthesize a model of a fabrication process that is likely to produce the desired semiconductor device. First, a desired device having one or more desired characteristics is modeled. Then, various process and material parameters, constraints, and actual measured data are used to synthesize one or more unique software models that represent a process flow likely to fabricate the desired device. If more than one process flow is modeled, various parameters are modified iteratively until a unique process flow model is synthesized.
