    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.
