  • Publication number: 20250362221
    Abstract: Some embodiments described herein relate to a method of calibrating a device sensor that includes inserting a reference sensor into a calibration system. In an embodiment, the calibration system includes a light source, and a photonic detector. In an embodiment, the method further includes measuring a reference transmission value of an amount of light from the light source that is transmitted through the reference sensor towards the photonic detector, and inserting the device sensor into the calibration system. In an embodiment, the method further includes measuring a transmission value of the amount of light from the light source that is transmitted through the device sensor towards the photonic detector, and calculating a scaling factor for the device sensor. In an embodiment, the scaling factor equalizes the transmission value of the device sensor to the reference transmission value of the reference sensor.

  • Publication number: 20250336715
    Abstract: Embodiments herein are generally directed to systems and methods for removing metal oxide layers for back-end-of-line processes. A substrate processing system includes a processing chamber configured to generate a plasma within the processing chamber, a substrate electrode embedded within a substrate support assembly disposed within the processing chamber, a radio frequency (RF) generator assembly coupled to the substrate electrode, and a controller. The controller is configured to flow a cleaning gas over a surface of a substrate support disposed within a processing chamber and generate a radio frequency (RF) pulsed bias that delivers an RF waveform for a first portion of a pulse period and halts the delivery of the RF waveform for a second portion of the pulse period and apply the RF pulsed bias to the substrate electrode while the plasma is present in the processing chamber.

  • Publication number: 20240213007
    Abstract: Methods and apparatus for controlling processing of a substrate within a process chamber, comprising: performing statistical analysis on measurements of deposition profile of at least one previously processed substrate processed in the process chamber, wherein the deposition profile is based at least on modulating a power parameter of at least one power supply affecting a magnetron in the process chamber; determining, based on the statistical analysis, a model of the deposition profile as a function of at least the power parameter; fitting the measurements of deposition profile to the model; determining a power parameter setpoint for the at least one power supply using the fitted model based on a desired deposition profile of an unprocessed substrate; and setting the power parameter setpoint for processing the unprocessed substrate.
