  • High voltage termination structure of a power semiconductor device
    Patent number: 10636900
    Abstract: A power semiconductor transistor includes an electrically conductive contact structure including a plurality of contacts. A first one of the contacts is electrically connected to both a first load terminal and a first zone of a doped semiconductor structure. A second one of the contacts is electrically coupled to one of the first load terminal and a control electrode. The second contact laterally overlaps with both a second zone of the doped semiconductor structure, and a gap is formed between two adjacent field plates. The second zone of the doped semiconductor structure terminates in a section laterally overlapping with the gap.
    Type: Grant
