Claim 0:
1. A method of calibrating a resist model, the method comprising:
generating 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;
predicting 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
adjusting 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.
