Abstract:
A system and method including a processing device. The processing device receives data including a first set of plasma exposure values each associated with a respective plasma element of a plurality of plasma elements designed to generate plasma related fluxes. The processing device causes a plasma controller to activate the set of plasma elements based on the data to expose a substrate to the plasma related fluxes generated by the set of plasma elements during a plasma process. Each respective plasma element of the set of plasma elements is activated for a duration based on a respective plasma exposure value from the first plurality of plasma exposure values that is associated with the respective plasma element.
