  • 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.
