Claim 18:
19. A non-transitory machine-readable storage medium storing instructions which, when executed cause a processing device to perform operations comprising:
obtaining, by a processor, sensor data associated with a deposition process performed in a process chamber to deposit a film stack on a surface of a substrate, wherein the film stack comprises a plurality of layers of a first material and a plurality of layers of a second material;
obtaining metrology data associated with the film stack;
training a first machine-learning model based on the sensor data and the metrology data, wherein the first machine-learning model is trained to generate predictive metrology data associated with layers of the first material; and
training a second machine-learning model based on the sensor data and the metrology data, wherein the second machine-learning model is trained to generate predictive metrology data associated with layers of the second material.
