Abstract
A super junction semiconductor device includes a semiconductor portion having strip structures in a cell area. Each strip structure has a compensation structure with first and second sections inversely provided on opposite sides of a fill structure. Each section has first and second compensation layers of complementary conductivity types. The strip structures are linear stripes extending through the cell area in a first lateral direction and into an edge area surrounding the cell area in lateral directions. Each strip structure has an end section with a termination portion in the edge area in which the first compensation layer of the first section is connected with the first compensation layer of the second section via a first conductivity layer, and the second compensation layer of the first section is connected with the second compensation layer of the second section via a second conductivity layer.
