    Abstract: Systems and methods of the disclosure perform in situ sensing and real time compensation of various non-uniformities in substrate processing systems. A plasma non-uniformity is sensed by determining a temperature distribution across a matrix of a plurality of micro-heaters disposed in the substrate support. Alternatively, the plasma non-uniformity is sensed by determining heat flux through the substrate support using the matrix heaters and one or more heaters used to heat one or more zones of the substrate support. The plasma non-uniformity is compensated by adjusting one or more parameters such as power supplied to the matrix heaters, RF power supplied to generate plasma, chemistry and/or flow rate of gas or gases used to generate plasma, settings of thermal control units or chillers, and so on. Additionally, non-uniformities inherent in the substrate support are sensed using the zone and matrix heaters and are compensated by adjusting the one or more parameters.

    Abstract: A method for coating a component of a plasma processing chamber is provided. An electrolytic oxidation coating is formed over a surface of the component, wherein the electrolytic oxidation coating has a plurality of pores, wherein the electrolytic oxidation coating has a thickness and at least some of the plurality of pores extends through the thickness of the electrolytic oxidation coating. An atomic layer deposition is deposited on the electrolytic oxidation coating. The atomic layer deposition comprises a plurality of cycles, where each cycle comprises flowing a first reactant, wherein the first reactant forms a first reactant layer in the pores of the electrolytic oxidation coating, wherein the first reactant layer extends through the thickness of the electrolytic oxidation coating, stopping the flow of the first reactant, flowing a second reactant, wherein the second reactant reacts with the first reactant layer, and stopping the flow of the second reactant.

    Abstract: A substrate support assembly for supporting a substrate includes a baseplate, a ceramic plate arranged on the baseplate, and N resistive heaters arranged in X rows and Y columns and coupled to the ceramic plate. X, Y, and N are integers greater than 1, and N is less than or equal to X*Y. Each of the N resistive heaters have a first terminal and a second terminal. The ceramic plate includes Y conductors arranged in a first layer of the ceramic plate, and X conductors arranged in a second layer of the ceramic plate. The first terminals of each resistive heater in one of the X rows are directly connected to the Y conductors, respectively, by first vias. Second terminals of each resistive heater in the one of the X rows are directly connected to one of the X conductors by second vias.
