Classification: CPC G  H | IPC G  H

Claim 1:
2. The method of claim 1, further comprising:
receiving historical spectral data collected during a prior substrate process performed for an additional prior substrate of the set of prior substrates;
obtaining a historical metrology measurement value for the additional prior substrate, the historical metrology measurement value generated based on additional historical metrology data collected by the metrology equipment for the additional prior substrate; and
generating the training data to train each of the plurality of machine learning models, wherein generating the training data comprises:
generating a training input comprising the historical spectral data; and
generating a target output for the training input, wherein the target output comprises the historical metrology measurement value for the additional prior substrate,

and wherein providing the training data to train each of the plurality of machine learning models comprises providing: (i) a set of training inputs comprising the training input; and (ii) a set of target outputs comprising the target outputs.
