Claim 10:
11. A device for calibrating a resist model, the device comprising:
a processor configured 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.
