Abstract
A semiconductor device includes a transistor cell region and a transition region. The transistor cell region includes a first portion of a super junction structure and a first contact structure electrically connecting a first load electrode with first source zones of transistor cells. The first source zones are formed on opposite sides of the first contact structure. The transition region directly adjoins to the transistor cell region and includes a second portion of the super junction structure and a second contact structure electrically connecting the first load electrode with a second source zone. The second source zone is formed only at a side of the second contact structure oriented to the transistor cell region.
