Claim 18:
19. A method for characterizing a specimen, comprising:
acquiring one or more training images of one or more features of a specimen with a characterization sub-system, wherein the specimen comprises a semiconductor wafer;
receiving one or more training three-dimensional (3D) design images of the one or more features of the specimen;
generating a deep learning predictive model based on the one or more training images and the one or more training 3D design images;
receiving one or more product 3D design images of one or more features of a specimen;
generating at least one of one or more simulated scanning electron microscopy images or one or more optical images of the one or more features of the specimen based on the one or more product 3D design images with the deep learning predictive model; and
determining one or more material characteristics of the specimen based on the at least one of one or more simulated scanning electron microscopy images or one or more simulated optical images.
