Classification: CPC H  G | IPC G  H

Claim 9:
10. A system comprising:
a memory; and
a processing device, coupled to the memory, to:
obtain 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;
obtain metrology data associated with the film stack;
train 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
train 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.
