  • Patent number: 10340432
    Abstract: A light emitting device is provided that includes an integral heat dissipation element. This heat dissipation element is included in the leadframe that is used to facilitate fabrication of the light emitting device, to provide a single common substrate that forms both the heat dissipation element and the conductive elements for coupling the light emitting device to external sources of power. The heat dissipation element may extend beyond the protective structure that surrounds the light emitting element to facilitate heat dissipation to the surrounding medium.

  • Patent number: 8994096
    Abstract: The invention relates to a multi-transistor, e.g. a two-transistor memory cell with an enhancement junction field effect transistor (JFET) as the access gate transistor. In one embodiment, the JFET is provided as a self-aligned JFET. Accordingly, and advantageous over the prior art, the invention allows for a method for manufacturing a multi-transistor, e.g. a two-transistor memory cell comprising a JFET as the access transistor without adding any additional masks and/or processing steps. Such a multi-transistor, e.g. a two-transistor memory cell according to invention, provides an improved reliability.

  • Patent number: 8749223
    Abstract: Various exemplary embodiments relate to an isolation device including a semiconductor layer and an insulation layer. The insulation layer insulates a central portion of the semiconductor layer. A high voltage terminal connects to the insulation layer, a first low voltage terminal connects to a first non-insulated portion of the semiconductor layer, and a second low voltage terminal connects to a second non-insulated portion of the semiconductor layer. The first and second low voltage terminals are electrically connected via the semiconductor layer. A voltage applied to the high voltage terminal influences the conductance of the semiconductor layer. The high voltage terminal is galvanically isolated from the first and second low voltage terminals.

  • Patent number: 8260098
    Abstract: An optocoupler device facilitates on-chip galvanic isolation. In accordance with various example embodiments, an optocoupler circuit includes a silicon-on-insulator substrate having a silicon layer on a buried insulator layer, a silicon-based light-emitting diode (LED) having a silicon p-n junction in the silicon layer, and a silicon-based photodetector in the silicon layer. The LED and photodetector are respectively connected to galvanically isolated circuits in the silicon layer. A local oxidation of silicon (LOCOS) isolation material and the buried insulator layer galvanically isolate the first circuit from the second circuit to prevent charge carriers from moving between the first and second circuits. The LED and photodetector communicate optically to pass signals between the galvanically isolated circuits.
