  • Abstract
    In this paper we report a novel ´all-epitaxial´ 1.2 kV normally-off JFET featuring a double channel to improve considerably the specific on-state resistance. The device relies on a succession of n and p+ stripes in the channel/gate region. A 30% reduction in the on-resistance is obtained when compared to a standard single channel normally-off JFET. Depending on the structure considered, the unipolar value of the specific on-state resistance for a 1.2 kV device is below 3 mΩcm2.
