Claim 16:
17. A system for characterizing a specimen, comprising:
a characterization sub-system configured to acquire one or more images of a specimen, wherein the specimen comprises a semiconductor wafer; and
a controller communicatively coupled to the characterization sub-system, the controller including one or more processors configured to execute a set of program instructions stored in memory, the set of program instructions configured to cause the one or more processors to:
receive one or more training images of one or more features of a specimen from the characterization sub-system;
receive one or more training three-dimensional (3D) design images corresponding to the one or more features of the specimen;
generate a deep learning predictive model based on the one or more training images and the one or more training 3D design images;
receive one or more product images of 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;
generate one or more simulated 3D 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
determine one or more material characteristics of the specimen based on the one or more simulated 3D design images.
