摘要:
A drift layer of a super junction semiconductor device includes first portions of a first conductivity type and second portions of a second conductivity type opposite to the first conductivity type. The first and second portions are formed both in a cell area and in an edge area surrounding the cell area, wherein an on-state or forward current through the drift layer flows through the first portions in the cell area. At least one of the first and second portions other than the first portions in the cell area includes an auxiliary structure or contains auxiliary impurities to locally reduce the avalanche rate. Locally reducing the avalanche rate increases the total voltage blocking capability of the super junction semiconductor device.

A semiconductor device includes a semiconductor body having a first surface and a second surface opposite to the first surface. A superjunction structure in the semiconductor body includes drift regions of a first conductivity type and compensation structures alternately disposed in a first direction parallel to the first surface. Each of the charge compensation structures includes a first semiconductor region of a second conductivity type complementary to the first conductivity type and a first trench including a second semiconductor region of the second conductivity type adjoining the first semiconductor region. The first semiconductor region and the first trench are disposed one after another in a second direction perpendicular to the first surface.

摘要:
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.
