Claim 19:
20. A method comprising:
obtaining a plurality of sensor values associated with a deposition process performed in a process chamber to deposit layers of film on a surface of a substrate;
applying a first machine-learning model to a first subset of the plurality of sensor values, the first machine-learning model trained based on historical sensor data and metrology data associated with layers of a first material;
applying a second machine-learning model to a second subset of the plurality of sensor values, the second machine-learning model trained based on the historical sensor data and metrology data associated with layers of a second material;
obtaining a first output of the first machine-learning model, the first output indicating first predictive metrology data for layers of the first material of the film; and
obtaining a second output of the second machine-learning model, the second output indicating second predictive metrology data for layers of the second material of the film.
