    Abstract: Methods and systems for rating a current substrate support assembly based on impedance circuit electron flow are provided. Data associated with an amount of radio frequency (RF) power flowed through an electrical component of a current substrate support assembly during a current testing process performed for the current substrate support assembly is provided as input to a trained machine learning model. One or more outputs of the trained machine learning model are obtained. A measurement value for an electron flow across an impedance circuit of the current substrate support assembly is extracted from the one or more outputs. In response to a determination that the extracted measurement value for the electron flow satisfies an electron flow criterion, a first quality rating is assigned to the current substrate support assembly.

  • Patent number: 12205818
    Abstract: Embodiments of the present technology include semiconductor processing methods to make boron-and-silicon-containing layers that have a changing atomic ratio of boron-to-silicon. The methods may include flowing a silicon-containing precursor into a substrate processing region of a semiconductor processing chamber, and also flowing a boron-containing precursor and molecular hydrogen (H2) into the substrate processing region of the semiconductor processing chamber. The boron-containing precursor and the H2 may be flowed at a boron-to-hydrogen flow rate ratio. The flow rate of the boron-containing precursor and the H2 may be increased while the boron-to-hydrogen flow rate ratio remains constant during the flow rate increase. The boron-and-silicon-containing layer may be deposited on a substrate, and may be characterized by a continuously increasing ratio of boron-to-silicon from a first surface in contact with the substrate to a second surface of the boron-and-silicon-containing layer furthest from the substrate.
