  • Publication number: 20140273313
    Abstract: A method and apparatus are disclosed which use a photoluminescent light intensity signature to characterize a processed photovoltaic substrate.
    Type: Application
    Filed: March 12, 2014
    Publication date: September 18, 2014
    Applicant: FIRST SOLAR, INC
    Inventors: Navneet Kumar, Amir Weiss
  • Publication number: 20130129593
    Abstract: The present invention provides compositions of matter useful as deposition agents for making structures, including thin film structures and hard coatings, on substrates and features of substrates. In an embodiment, for example, the present invention provides metal complexes having one or more diboranamide or diboranaphosphide ligands that are useful as chemical vapor deposition (CVD) and/or atomic layer deposition (ALD) precusors for making thin film structures and coatings. Metal complex CVD precursors are provided that possess volitilities sufficiently high so as to provide dense, smooth and homogenous thin films and coatings.
    Type: Application

  • Publication number: 20120107503
    Abstract: The present invention provides methods for making structures, including nanosized and microsized thin film structures that exhibit a high degree of smoothness useful for applications in microelectronics. Deposition processing of the invention utilize smoothing agents capable of selectively adjusting the relative rates of processes involved in thin film formation and growth to access enhanced nucleation densities resulting in smooth thin film structures, including ultrathin (e.g., <10 nm) smooth films.

  • Patent number: 8110503
    Abstract: Various processes and related systems are provided for making structures on substrate surfaces. Disclosed are methods of making a structure supported by a substrate by providing a substrate having a receiving surface and exposing at least a portion of the receiving surface to output from a remote plasma of an inert gas. The remote plasma has an energy low enough to substantially avoid etching or sputtering of the receiving surface but sufficient to generate a treated receiving surface. The treated surface is contacted with a deposition gas, thereby making the structure supported by the substrate.
    Type: Grant
