Claim 19:
20. A computer program product comprising a non-transitory computer readable medium having instructions therein, the instructions, upon execution by a computer system, configured to cause the computer system to at least:
generate a modeled resist contour of a resist structure based at least on a simulated aerial image of the resist structure;
predict, based on the modeled resist contour, the simulated aerial image, and at least one resist sidewall parameter of a set of resist sidewall parameters associated with the resist structure, a measurement of a portion of a waveform corresponding to an edge of an actual resist structure imaged by a metrology device; and
adjust the at least one resist sidewall parameter based on a comparison between the predicted measurement of the portion of the waveform and an actual measurement of the portion of the waveform corresponding to the edge of the actual resist structure imaged by the metrology device.
