Methods to reduce material surface roughness
Exemplary deposition methods may include delivering a silicon-containing precursor and a boron-containing precursor to a processing region of a semiconductor processing chamber. The methods may include providing a hydrogen-containing precursor with the silicon-containing precursor and the boron-containing precursor. A flow rate ratio of the hydrogen-containing precursor to either of the silicon-containing precursor or the boron-containing precursor is greater than or about 2:1. The methods may include forming a plasma of all precursors within the processing region of a semiconductor processing chamber. The methods may include depositing a silicon-and-boron material on a substrate disposed within the processing region of the semiconductor processing chamber.

INTEGRATED METHOD AND TOOL FOR HIGH QUALITY SELECTIVE SILICON NITRIDE DEPOSITION
Methods of manufacturing memory devices are provided. The method comprises pre-cleaning a top surface of a film stack, the film stack comprising alternating layers of a first material layer and a second material layer and having one or more of a memory hole and a slit pattern opening extending through the film stack; exposing the top surface of the film stack to a growth inhibitor; selectively depositing a silicon-containing dielectric layer in a region of the film stack; and densifying the silicon-containing dielectric layer. The processing method is performed in a processing tool without breaking vacuum.

Methods of forming high boron-content hard mask materials
An exemplary method may include delivering a boron-containing precursor to a processing region of a semiconductor processing chamber. The method may also include forming a plasma within the processing region of the semiconductor processing chamber from the boron-containing precursor. The method may further include depositing a boron-containing material on a substrate disposed within the processing region of the semiconductor processing chamber. The boron-containing material may include greater than 50% of boron. In some embodiments, the boron-containing material may include substantially all boron. In some embodiments, the method may further include delivering at least one of a germanium-containing precursor, an oxygen-containing precursor, a silicon-containing precursor, a phosphorus-containing precursor, a carbon-containing precursor, and/or a nitrogen-containing precursor to the processing region of the semiconductor processing chamber. The boron-containing material may further include at least one of germanium, oxygen, silicon, phosphorus, carbon, and/or nitrogen.
BORON CONCENTRATION TUNABILITY IN BORON-SILICON FILMS
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 (H.sub.2) into the substrate processing region of the semiconductor processing chamber. The boron-containing precursor and the H.sub.2 may be flowed at a boron-to-hydrogen flow rate ratio. The flow rate of the boron-containing precursor and the H.sub.2 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.
