摘要: An over-voltage protection device includes a substrate including an upper surface and a lower surface; a first electrode provided on the upper surface of the substrate; a second electrode provided on the lower surface on the substrate; a first conductive layer overlying the lower surface of the substrate, the first conductive region being a conductive region of a first type; a plurality of first conductive regions provided proximate the upper surface of the substrate, the plurality of first conductive regions being conductive regions of the first type; and a plurality of second conductive region provided proximate the upper surface of the substrate, the plurality of second conductive region being conductive regions of a second type. The plurality of the first conductive regions are provided in an alternating manner with the plurality of second conductive regions. The first electrode is contacting the plurality of the first and second conductive regions.

摘要: A power device includes a substrate assembly including an upper surface and a lower surface. The substrate assembly includes a first layer and a second layer. The first layer overlies the second layer and has different conductivity than the second layer. A first electrode is provided proximate the upper surface. A second electrode is provided proximate the upper surface and is spaced apart from the first electrode. The second layer is configured to provide a current path between the first and second electrodes.

摘要: A switching device is described having a semiconductor substrate with a front side and a back side. The switching device includes a first transistor which includes a first region adjacent the front side, a second region within the first region, the semiconductor substrate, and at least one island region adjacent the backside. The switching device also includes a second transistor which includes the first region, the second region, the semiconductor substrate, and a third region coupled to the at least one island region.
