  • MOS semiconductor device which has high blocking voltage
    Patent number: 4954868
    Abstract: A semiconductor component which comprises a planar structure which has a channel stopper 7 formed at one edge and a field electrode which covers a pn-junction 3 of the planar zones adjoining the edge 4. The blocking voltage can be increased by providing a channel stopper field plate 19 arranged over the channel stopper and an anode field plate 18 arranged over the field electrode and these field plates are spaced a greater distance from the surface 8 of the semiconductor body between the electrodes 18 and 19 and they have over the channel stopper electrode and the gate electrode.
