USING ELEMENTAL MAPS INFORMATION FROM X-RAY ENERGY-DISPERSIVE SPECTROSCOPY LINE SCAN ANALYSIS TO CREATE PROCESS MODELS

Implementations disclosed describe a method of using a model to predict a change of a physical state of a sample caused by one or more stages of a technological process in a substrate processing apparatus and obtaining imaging data associated with an actual performance of the one or more stages of the technological process. The imaging data includes a distribution of one or more chemical elements for a number of regions of the sample. The method further includes identifying, based on the imaging data, a difference between the predicted change of the physical state of the sample and an actual change of the physical state of the sample caused by the actual performance of the one or more stages of the technological process. The method further includes determining parameters of the model based on the identified difference.
