Abstract: During chemical mechanical polishing of a substrate, a signal value that depends on a thickness of a layer in a measurement spot on a substrate undergoing polishing is determined by a first in-situ monitoring system. An image of at least the measurement spot of the substrate is generated by a second in-situ imaging system. Machine vision processing, e.g., a convolutional neural network, is used to determine a characterizing value for the measurement spot based on the image. Then a measurement value is calculated based on both the characterizing value and the signal value.

Abstract: The present technology includes improved gas distribution designs for forming uniform plasmas during semiconductor processing operations or for treating the interior of semiconductor processing chambers. While conventional gas distribution assemblies may receive a specific reactant or reactant ratio which is then distributed into the plasma region, the presently described technology allows for improved control of the reactant input distribution. The technology allows for separate flows of reactants to different regions of the plasma to offset any irregularities observed in process uniformity. A first precursor may be delivered to the center of the plasma above the center of the substrate/pedestal while a second precursor may be delivered to an outer portion of the plasma above an outer portion of the substrate/pedestal. In so doing, a substrate residing on the pedestal may experience a more uniform etch or deposition profile across the entire surface.
