  • Publication number: 20240038601
    Abstract: An electronic device manufacturing system including a substrate-holder configured to secure a substrate during processing and a controller, operatively coupled to the substrate-holder. The controller is configured to apply, to an electrode of the substrate-holder, a first voltage. The controller is further configured to determine a first impedance value between the substrate-holder and the substrate. The controller is further configured to determine a delta value between the first impedance value and a predetermined second impedance value, and determine whether the delta value satisfies a threshold criterion. Responsive to the delta value failing to satisfy the threshold criterion, the controller is further configured to apply a second voltage to the substrate, wherein the second voltage is greater than the first voltage.

  • Publication number: 20230359179
    Abstract: An electronic device manufacturing system capable of obtaining metrology data associated with a deposition process performed on a substrate according to a process recipe, wherein the deposition process generates a plurality of layers on a surface of the substrate. The manufacturing system can further obtain an expected profile associate with the process recipe, wherein the expected profile comprises a plurality of values indicative of a desired thickness for a plurality of layers of the process recipe. The manufacturing system can further generate a correction profile based on the metrology data and the expected profile, wherein the correction profile comprises a deposition time offset value for at least one layer of the plurality of layers. The manufacturing system can further generate an updated process recipe by applying the correction profile to the process recipe and cause a deposition step to be performed on the substrate according to the updated process recipe.
