  • Patent number: 10546964
    Abstract: A solar cell with a molybdenum back electrode layer and a molybdenum selenide ohmic contact layer over the molybdenum back electrode, is provided. The molybdenum selenide layer includes an accurately controlled thickness. A distinct interface exists between the molybdenum back electrode layer and the molybdenum silicide layer. The molybdenum silicide layer is produced by forming a molybdenum layer or a molybdenum nitride layer or a molybdenum oxide layer over an initially formed molybdenum layer such that an interface exists between the two layers. A selenization and sulfurization process is carried out to selectively convert the molybdenum-containing layer to molybdenum selenide but not the original molybdenum back electrode layer which remains as a molybdenum layer.

  • Patent number: 9741655
    Abstract: An integrated circuit common-mode electromagnetic interference filter incorporating electro-static discharge protection comprising two inductive coils is provided. A pair of primary and secondary spiral inductor coils is disposed corresponding to each other. A dielectric layer is used to separate the primary spiral inductor coil from the secondary spiral inductor coil electrically. Resistivity of a high-resistance substrate is more than 100 ?-cm for supporting the primary spiral inductor coil, the secondary spiral inductor coil and the dielectric layer thereon. The proposed filter structure can be formed in integrated circuit (IC) back-end processes and thus be extraordinarily advantageous of effectively eliminating electromagnetic interferences and having electrostatic protection effect at the same time, while having small footprint.
