  • HIGH TRANSPARENCY, HIGH HAZE NANOSTRUCTURED STRUCTURES
    Publication number: 20230365457
    Abstract: The invention relates generally to optically high transparency and high haze structures and, more particularly, to plastic, e.g., polymer, and glass structures having a sub-wavelength texture formed on a surface thereof, which is effective to impart the optical properties of high transparency and high haze to the structures. The texture is in a grass-like or needle-like form. Additionally, the optically high transparency and high haze structures may include a transparent conductor. Furthermore, the glass structures may exhibit a self-cleaning function.
    Type: Application

  • Surface treatment of substrates using passivation layers
    Patent number: 11094528
    Abstract: Processes and apparatuses for the treatment of semiconductor workpieces are provided. In some embodiments, a method can include placing the workpiece in a processing chamber. The processing chamber can be separated from a plasma chamber by a separation grid assembly. The method can include forming a passivation layer on the workpiece in the processing chamber using radicals generated in a first plasma in the plasma chamber. The method can include performing a surface treatment process on the workpiece in the processing chamber using a second plasma generated in the plasma chamber.
