    摘要: A semiconductor device with a dynamic gate drain capacitance. One embodiment provides a semiconductor device. The device includes a semiconductor substrate, a field effect transistor structure including a source region, a first body region, a drain region, a gate electrode structure and a gate insulating layer. The gate insulating layer is arranged between the gate electrode structure and the body region. The gate electrode structure and the drain region partially form a capacitor structure including a gate-drain capacitance configured to dynamically change with varying reverse voltages applied between the source and drain regions. The gate-drain capacitance includes at least one local maximum at a given threshold or a plateau-like course at given reverse voltage.

    摘要: A semiconductor component with a two-stage body zone. One embodiment provides semiconductor component including a drift zone, and a compensation zone of a second conduction type. The compensation zone is arranged in the drift zone. A source zone and a body zone is provided. The body zone is arranged between the source zone and the drift zone. A gate electrode is arranged adjacent to the body zone. The body zone has a first body zone section and a second body zone section, which are adjacent to one another along the gate dielectric and of which the first body zone section is doped more highly than the second body zone section.

    摘要: A semiconductor device with a charge carrier compensation structure in a semiconductor body and to a method for its production. The semiconductor body includes drift zones of a first conduction type and charge compensation zones of a second conduction type complementing the first conduction type. The drift zones include a semiconductor material applied in epitaxial growth zones, wherein the epitaxial growth zones include an epitaxially grown semiconductor material which is non-doped to lightly doped. Towards the substrate, the epitaxial growth zones are provided with a first conduction type incorporated by ion implantation over the entire surface and with selectively introduced doping material zones of a second, complementary conduction type. Towards the front side, the epitaxial growth zones are provided with a second, complementary conduction type incorporated by ion implantation over the entire surface and with selectively introduced doping material zones of the first conduction type.

    摘要: A power semiconductor element having a lightly doped drift and buffer layer is disclosed. One embodiment has, underneath and between deep well regions of a first conductivity type, a lightly doped drift and buffer layer of a second conductivity type. The drift and buffer layer has a minimum vertical extension between a drain contact layer on the adjacent surface of a semiconductor substrate and the bottom of the deepest well region which is at least equal to a minimum lateral distance between the deep well regions. The vertical extension can also be determined such that a total amount of dopant per unit area in the drift and buffer layer is larger then a breakdown charge amount at breakdown voltage.
