    摘要： A semiconductor component has a semiconductor body zone, a first electrically conductive layer adjacent to the semiconductor body zone, a first dielectric layer with first dielectric properties and a second dielectric layer with second dielectric properties. The first dielectric properties differ from the second dielectric properties. The first dielectric layer and the second dielectric layer are arranged between the semiconductor body zone and the first electrically conductive layer. A second electrically conductive layer is applied between the first dielectric layer and the second dielectric layer. A first voltage divider is switched between the first electrically conductive layer and the semiconductor body zone. The second electrically conductive layer is electrically conductively connected only to the voltage divider.

    摘要： In order to produce a cost-effective fuse in chip design, which is applied to a carrier substrate made of a Al2O3 ceramic having a high thermal conductivity, and which is provided with a fusible metallic conductor and a cover layer, in which the melting point of the metallic conductor may be defined reliably, it is suggested that an intermediate layer having low thermal conductivity be positioned between the carrier substrate and the metallic conductor, the intermediate layer being formed by a low-melting-point inorganic glass paste applied in the screen-printing method or an organic intermediate layer applied in island printing. Furthermore, a method for manufacturing the fuse is specified.

    摘要： A normally-off JFET is provided. The normally-off JFET includes a channel region of a first conductivity type, a floating semiconductor region of a second conductivity type adjoining the channel region, and a contact region of the first conductivity type adjoining the floating semiconductor region. The floating semiconductor region is arranged between the contact region and the channel region. Further, a normally-off semiconductor switch is provided.

    摘要： A vertical trench transistor has a first electrode, a second electrode and also a semiconductor body arranged between the first and second electrodes, there being formed in the semiconductor body a plurality of transistor cells comprising source region, body region, drift region and gate electrode and also contact holes for making contact with the source and body regions, contact being made with the source and body regions by means of the first electrode, and at least the bottom of each contact hole adjoining at least one drift region, so that Schottky contacts between the first electrode and corresponding drift regions are formed at the bottoms of the contact holes. The dimensions and configurations of the body regions or of the body contact regions optionally arranged between body regions and contact holes are chosen in such a way as to avoid excessive increases in electric fields at the edges of the contact hole bottoms.
