    Abstract: [Problem to be solved] To produce an SiO powder having a rounded spherical particulate shape and a small particle diameter; and further having a low degree of impurity contamination, efficiently and economically.
    [Solution] A mixture of Si and SiO2 as an SiO gas generation raw material 9 is loaded into a crucible 2. The mixture in the crucible 2 is heated under a reduced pressure so as to generate SiO gas. The generated SiO gas is accumulated on a deposition base 5 rotating on the crucible 2. When SiO deposit 10 accumulated on the deposition base 5 is scraped off with a blade 7, a tip of the blade 7 is separated from a surface of the deposition base 5, and in a state in which a portion of the SiO deposit 10 accumulated on the deposition base 5 is left on the deposition base 5, the remaining SiO deposit 10 is scraped off by the blade 7 and collected as an SiO powder 11.

    Abstract: Exemplary methods of coating a metal-containing component are described. The methods are developed to increase corrosion resistance and improve coating adhesion to a metal substrate. The methods include forming a bonding layer on a metal substrate, where the bonding layer includes an oxide of a metal in the metal substrate. The coating methods further include depositing a stress buffer layer on the bonding layer, where the stress buffer layer is characterized by a stress buffer layer coefficient of thermal expansion (CTE) that is less than a metal substrate CTE and a bonding layer CTE. The coating methods also include depositing an environmental barrier layer on the stress buffer layer, where a ratio of the metal substrate CTE to an environmental barrier layer CTE is greater than or about 20:1, and where the environmental barrier layer includes silicon oxide. The metal-containing components may be used in fabrication equipment for electronic devices.

    Abstract: Exemplary methods of semiconductor processing, such as methods of depositing a molybdenum-containing material on a substrate, may include providing a molybdenum-containing precursor to a processing region of a semiconductor processing chamber in which the substrate is located. The molybdenum-containing precursor may include a molybdenum complex according to Compound I: R may be methyl or ethyl, R′ may be methyl or ethyl, R″ may be methyl, ethyl, or propyl, and n may be equal to 1 or 2. Contacting the substrate with the molybdenum-containing precursor may deposit the molybdenum-containing material on the substrate.

    Abstract: An inkjet printer printhead, member thereof, or other component has an internal cavity that has a protective coating. Further surfaces of the component may have the protective coating. To make the protective coating, a target thickness for a film of HfO2 (hafnia) is selected, that will avoid formation of pinholes, thin spots and nodule growth. Using atomic layer deposition (ALD), with the processing adjusted for the target thickness, the film of HfO2 is deposited as a conformal layer on the component, including on a surface of the internal cavity, to form a coated component. A non-wetting coating can be included over the film of HfO2.
