Abstract: A method is provided, the method comprising sampling at least one parameter characteristic of processing performed on a workpiece in at least one processing step, and modeling the at least one characteristic parameter sampled using an adaptive sampling processing model, treating sampling as an integrated part of a dynamic control environment, varying the sampling based upon at least one of situational information, upstream events and requirements of run-to-run controllers. The method also comprises applying the adaptive sampling processing model to modify the processing performed in the at least one processing step.

Abstract: A method of controlling a conductive layer deposition process includes depositing a conductive layer onto a semiconductor wafer based upon a deposition recipe, measuring a thickness of the conductive layer deposited on the semiconductor wafer, determining whether the measured thickness of the conductive layer is within a predetermined tolerance, and revising the deposition recipe if the thickness of the conductive layer is not within the predetermined tolerance.
