  • Patent number: 11289387
    Abstract: Methods and apparatus perform backside via reveal processes using a centralized control framework for multiple process tools. In some embodiments, a method for performing a backside via reveal process may include receiving process tool operational parameters from process tools involved in the backside via reveal process by a central controller, receiving sensor metrology data from at least one or more of the process tools involved in the backside via reveal process, and altering the backside reveal process based, at least in part, on the process tool operational parameters and the sensor metrology data by adjusting two or more of the process tools involved in the backside via reveal process. The profile parameters are configured to prevent backside via breakage during a chemical mechanical polishing (CMP) process.

  • Publication number: 20210057292
    Abstract: Methods and apparatus for chemical mechanical planarization (CMP) of a polymer or epoxy-based layer. In some embodiments, the method may comprise obtaining an endpoint for polymer or epoxy-based material for use in a CMP process, the CMP process configured to polish polymer or epoxy-based material, monitoring the polymer or epoxy-based layer with an endpoint detection apparatus configured to monitor polymer or epoxy-based material, polishing the polymer or epoxy-based layer with the CMP process, detecting when the polymer or epoxy-based layer has reached the endpoint for the CMP process, and halting the CMP process when the endpoint is detected. The endpoint detection apparatus may further comprise an optical detection apparatus configured to operate at a wavelength of approximately 200 nm to approximately 1700 nm to reduce step height of the polymer or epoxy-based layer.

  • Publication number: 20200306931
    Abstract: Methods and apparatus for removing particles from a substrate surface after a chemical mechanical polish. In some embodiments, the apparatus may include a manifold configured to receive and atomize a fluid and at least one spray nozzle mounted to the manifold and configured to spray the atomized fluid in a divergent spray pattern such that the substrate surface is cleansed when impinged by spray from the at least one spray nozzle, wherein the at least one spray nozzle sprays the atomized fluid at a pressure of approximately 30 psi to approximately 2500 psi.
