  • Publication number: 20240355627
    Abstract: A planarization tool is configured to monitor one or more operational parameters of the planarization tool. The planarization tool may include a superconductor-based monitoring system that is configured to monitor a thickness of a layer on a semiconductor wafer that is processed by the planarization tool. The superconductor-based monitoring system may include a superconductor-based sensor that is configured to generate a signal that is based on an induced magnetic field through the layer on the semiconductor wafer. The signal may be provided to a controller of the planarization tool. The controller may determine a thickness of the layer based on the signal. The controller may provide one or more control signals to the polishing head to control one or more operational parameters such as a down force of the semiconductor wafer against the polishing pad and/or a rotational speed of the semiconductor wafer against the polishing pad, among other examples.
