Abstract: The invention relates to a semiconductor component with enhanced avalanche resistance. At the nominal current of this semiconductor component, in the event of an avalanche the voltage applied between two electrodes is 6% or more above the static reverse voltage at the same temperature.

Abstract: A compensation component and a process for production thereof includes a semiconductor body having first and second electrodes, a drift zone disposed therebetween, and areas of a first conductivity type and a second conductivity type opposite the first conductivity type disposed in the drift zone. Higher doped zones of the first type are inlaid in a weaker doped environment of the second type closer to the first electrode and higher doped zones of the second type are inlaid in a weaker doped environment of the first type closer to the second electrode. The drift zone is complementary so that, in a direction between the electrodes, a more highly doped zone of the first type adjoins a more weakly doped environment of the first type, and a more weakly doped environment of the second type adjoins a more highly doped zone of the second type.

Abstract: A semiconductor component includes a charge compensation structure wherein locations with a maximum local field strength are positioned in a compensation edge region of the charge compensation structure. Thus, an electrical parameter such as the on resistance of the semiconductor component can be substantially improved without influencing or impairing further parameters such as the breakdown voltage and the robustness with respect to TRAPATT oscillations. Methods of fabricating a semiconductor component with a charge compensation structure are also provided.

Abstract: Charge balancing is achieved in a compensation component by creating compensation regions having different thickness. In this manner, the ripple of the electric field can be chosen to have approximately the same magnitude in all of the compensation regions.

Abstract: A semiconductor component includes first and second connection zones formed in a semiconductor body, a channel zone surrounding the second connection zone in the semiconductor body, and a drift path that is formed between the channel zone and the first connection zone and contains a compensation zone. The compensation zone has a complementary conduction type with respect to the drift zone and includes at least two segments. A distance between the two adjacent segments is chosen such that the punch-through voltage between these segments lies in a voltage range that corresponds to the voltage range assumed by the voltage drop across the drift path at currents situated between the rated current and twice the rated current.

Abstract: A vertically structured semiconductor power module is described. A layer thickness of a substrate of the power module between a pn junction and a metallized back is chosen in such a manner that a space charge region produced in the semiconductor module extends as far as the back when a blocking voltage between a source and a drain electrode is applied before a field strength produced by the applied blocking voltage reaches a critical value.
