  • Publication number: 20230343627
    Abstract: A component of a semiconductor processing chamber formed of a metal matrix component having an anodized layer on a surface thereof. The anodized layer comprises an aluminum oxide layer and is formed over an AlSic component. The anodized layer provides the component with protection against corrosion due to plasma processing gases, as the anodized layer provides a protective coating. A layer of aluminum is plated over a surface of the component and the aluminum layer is subsequently anodized to form the protective layer.
