    摘要: A semiconductor device includes a first semiconductor substrate of a first band-gap material and a second semiconductor substrate of a second band-gap material. The second band-gap material has a lower band-gap than the first band-gap material. A heterojunction is formed between the first semiconductor substrate and the second semiconductor substrate substantially in a first plane. The semiconductor device further includes, in a cross-section which is perpendicular to the first plane, a first semiconductor region of a first conductivity type and a second semiconductor region of the first conductivity type both of which extend from the second semiconductor substrate at least partially into the first semiconductor substrate. The first and second semiconductor regions are spaced in the first semiconductor substrate from each other in a direction parallel to the first plane by a first distance which is arranged in an area proximate to the heterojunction and which is larger than a second distance which is arranged in an area distal to the heterojunction.

    摘要: A semiconductor device with a semiconductor body and method for its production is disclosed. The semiconductor body includes drift zones of epitaxially grown semiconductor material of a first conduction type. The semiconductor body further includes charge compensation zones of a second conduction type complementing the first conduction type, which are arranged laterally adjacent to the drift zones. The charge compensation zones are provided with a laterally limited charge compensation zone doping, which is introduced into the epitaxially grown semiconductor material. The epitaxially grown semiconductor material includes 20 to 80 atomic % of the doping material of the drift zones and a doping material balance of 80 to 20 atomic % introduced by ion implantation and diffusion.

    摘要: A semiconductor component includes a body with a drift zone, a source zone, a body zone, and a drain zone. A gate forms a MOS structure with the drift zone, with the source zone and with the body zone. An edge termination between the lateral edge and the MOS structure includes a plurality of field rings which enclose the MOS structure. The lateral edge is at the same potential as the drift zone, and the edge termination reduces voltage between the lateral edge and the source zone. A horizontally extending edge plate is disposed at the front side between the lateral edge and the edge termination. The edge plate is at the same potential as the drift zone and forms a plate capacitor structure including a field plate lying above the edge plate.
