  • Publication number: 20230063929
    Abstract: Embodiments described herein relate to layered structures having a top surface which is hydrophobic for reducing the wetting of water or ice on the layered structure without requiring reapplication. In one or more embodiments, a layered structure is provided and includes a coating containing silicon, oxygen, and carbon disposed over a substrate and an interface disposed between the substrate and the coating. The substrate is at least partially transparent to visible light, a concentration of carbon in the coating is greater at a top surface of the coating than the interface, and the top surface of the coating is disposed on the opposite side of the coating than the interface.

  • Patent number: 11530478
    Abstract: A method of depositing a coating and a layered structure is provided. A coating is deposited on a substrate to make a layered structure, such that an interface between the coating and the substrate is formed. The coating includes silicon, oxygen, and carbon, where the carbon doping in the coating increases between the interface and the top surface of the coating. The top surface of the coating is inherently hydrophobic and icephobic, and reduces the wetting of water or ice film on the layered structure, without requiring reapplication of the coating.

  • Patent number: 11355391
    Abstract: The present disclosure generally relates to methods for processing of substrates, and more particularly relates to methods for forming a metal gapfill. In one implementation, the method includes forming a metal gapfill in an opening using a multi-step process. The multi-step process includes forming a first portion of the metal gapfill, performing a sputter process to form one or more layers on one or more side walls, and growing a second portion of the metal gapfill to fill the opening with the metal gapfill. The metal gapfill formed by the multi-step process is seamless, and the one or more layers formed on the one or more side walls seal any gaps or defects between the metal gapfill and the side walls. As a result, fluids utilized in subsequent processes do not diffuse through the metal gapfill.
