Particle defect prediction and correction based on process chamber modeling

Abstract

A method includes providing initial process conditions to a model associated with a process chamber. The method further includes providing an indication of one or more adjustments to the process chamber resulting in final process conditions to the model. The method further includes obtaining an indication of first gas backflow to a substrate support of the process chamber from the model. The method further includes generating updated one or more adjustments to the process chamber. The method further includes providing an indication of the updated one or more adjustments to the model. The method further includes obtaining from the model an indication of second gas backflow to the substrate support. The method further includes performing a corrective action based on the updated one or more adjustments.
