| 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.
