Claim 15:
16. 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 on a simulated aerial image of the resist structure and one or more parameters of the resist model;
predict a metrology contour of the resist structure from the modeled resist contour and information of an actual resist structure obtained by a metrology device, wherein the predicted metrology contour is a function of one or more values of the modeled resist contour and of one or more values of the information ; and
adjust one or more parameters of the resist model based on a comparison between the predicted metrology contour and an actual metrology contour of the actual resist structure obtained by the metrology device.
