  • Apparatus and methods of electrically conductive optical semiconductor coating
    Patent number: 10228495
    Abstract: A method of coating an optical substrate with a transparent, electrically conductive coating includes depositing a semiconductor coating over a surface of an optical substrate. The semiconductor coating has broadband optical transmittance. Channels are formed in the semiconductor coating. The method includes coating over the semiconductor coating and filling the channels with a doped semiconductor. The doped semiconductor is removed from the semiconductor coating, leaving the doped semiconductor in the channels.
    Type: Grant

  • Spatially controlled conductivity in transparent oxide coatings
    Patent number: 9952355
    Abstract: A method of coating an optical substrate includes depositing a semiconductor coating over a surface of an optical substrate, wherein the semiconductor coating has broadband optical transmittance. Portions of the semiconductor coating are doped to form a spatially varied pattern of doped semiconductor in the semiconductor coating. The method includes annealing the semiconductor coating to do at least one of: increase oxygen in undoped areas of the semiconductor coating; or reduce oxygen in doped areas of the semiconductor coating.
