Claim 12:
13. A metrology system comprising:
an optical metrology tool comprising an optical probe source and an optical detector and a processor configured to produce an optical metrology output from data produced by the optical detector when an optical probe is directed onto one or more features on a processed substrate; and
a metrology machine learning model that has been trained using a training set of (i) profiles, critical dimensions, and/or contours for a plurality of features, and (ii) optical metrology outputs for said plurality of features, wherein the metrology machine learning model is configured to:
receive the optical metrology output from the optical metrology tool; and
output the profile, critical dimension, and/or contour of the one or more features on the processed substrate.
