  • Patent number: 8273595
    Abstract: The present invention provides for cost-efficient methods for on-line deposition of semi-conducting metallic layers. More specifically, the present invention provides on-line pyrolytic deposition methods for deposition of p-type, n-type and i-type semi-conducting metallic layers in the float glass production process. Furthermore, the present invention provides for on-line pyrolytic deposition methods for production of single-, double-, triple- and multi-junction p-(i-)n and n-(i-)p type semi-conducting metal layers. Such p-type, n-type and i-type semi-conducting metal layers are useful in the photovoltaic industry and attractive to manufacturers of photovoltaic modules as “value-added” products.

  • Patent number: 5306651
    Abstract: A process for preparing a polycrystalline semiconductor thin film transistor wherein a non-singlecrystalline semiconductor formed on a transparent insulating substrate is annealed by laser beams, such process comprising forming a gate insulation layer and a gate electrode on the non-singlecrystalline semiconductor; implanting impurity ions into a source-drain region of the semiconductor wherein the gate electrode is used as a mask, and irradiating laser beams from the rear surface side of the transparent insulating substrate to thereby polycrystallize the non-singlecrystalline semiconductor under the gate electrode or improve the crystallinity of the semiconductor without causing the non-singlecrystalline semiconductor in a completely molten state.
