    Abstract: Examples of the present technology include semiconductor processing methods to form boron-containing materials on substrates. Exemplary processing methods may include delivering a deposition precursor that includes a boron-containing precursor to a processing region of a semiconductor processing chamber. A plasma may be formed from the deposition precursor within the processing region of the semiconductor processing chamber. The methods may further include depositing a boron-containing material on a substrate disposed within the processing region of the semiconductor processing chamber, where the substrate is characterized by a temperature of less than or about 50° C. The as-deposited boron-containing material may be characterized by a surface roughness of less than or about 2 nm, and a stress level of less-than or about −500 MPa. In some embodiments, a layer of the boron-containing material may function as a hardmask.

    Abstract: Examples of the present technology include semiconductor processing methods that provide a substrate in a substrate processing region of a substrate processing chamber, where the substrate is maintained at a temperature less than or about 50° C. A plasma may be generated from the hydrocarbon-containing precursor, and a carbon-containing material may be deposited from the plasma on the substrate. The carbon-containing material may include diamond-like-carbon, and may have greater than or about 60% of the carbon atoms with sp3 hybridized bonds.
