Claim 19:
20. 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 images of the one or more features of a specimen, wherein the one or more product images comprise at least one of one or more scanning electron microscopy images or one or more optical images;
generating one or more simulated design images of the one or more features of the specimen based on the one or more product images with the deep learning predictive model; and
determining one or more characteristics of the specimen based on the one or more simulated design images, wherein the one or more characteristics of the specimen comprise a material characteristic of the specimen.
