Abstract (en)

[origin: WO9953550A1] The invention relates to a high-voltage edge termination for planar structures which comprise a semiconductor body (1 to 4) of a first conduction type. At least one of the magnetoresistors (7, 17) which is separated from the semiconductor body by an insulating layer (9) is provided on the same in the edge area thereof. Floating regions (5, 15, 25) of the second conduction type are provided in the edge area of the semiconductor body (1 to 4). The floating regions are separated from one another in such a way that the zones between the floating regions (5, 15, 25) are cleared when a voltage which is lower in comparison to the breakdown voltage of the semiconductor body (1 to 4) is applied to the floating regions (5, 15, 25).
