  • Publication number: 20200378011
    Abstract: Coatings applicable to a variety of substrate articles, structures, materials, and equipment are described. In various applications, the substrate includes metal surface susceptible to formation of oxide, nitride, fluoride, or chloride of such metal thereon, wherein the metal surface is configured to be contacted in use with gas, solid, or liquid that is reactive therewith to form a reaction product that is deleterious to the substrate article, structure, material, or equipment. The metal surface is coated with a protective coating preventing reaction of the coated surface with the reactive gas, and/or otherwise improving the electrical, chemical, thermal, or structural properties of the substrate article or equipment. Various methods of coating the metal surface are described, and for selecting the coating material that is utilized.

  • Patent number: 10770330
    Abstract: An electrostatic chuck with a generally non-arcuate top surface shaped protrusions that has edge surfaces similar to a portion of a ellipse. The structure of the protrusions leads to the reduction of particulate material generated by interaction between the supported substrate and chuck. Reduced levels of scratching, abrasion, wear and particulate generation are achieved by improved smoothing and flattening of the protrusion surface.

  • Patent number: 10734270
    Abstract: A vacuum chuck with polymeric embossments is disclosed. The polymeric embossments are formed on the surface of a base substrate and are lapped to a flatness such that a wafer substrate clamped by the vacuum chuck has a peak to valley flatness that is less than a peak to valley flatness across the base substrate. Lapping of the polymeric embossments accommodates for variations in the flatness of the base substrate so long as the embossments are tall enough to stand over the peak to valley height variations in the base substrate.
