Patent AT-E401671-T1: [Translated] HALL EFFECT ELEMENT WITH INTEGRATED DEVIATION CONTROL AND METHOD FOR OPERATING SUCH AN ELEMENT FOR REDUCING THE ZERO POINT DEVIATION
A Hall-effect element includes an isolating layer and an active layer of a first electrical conductivity type disposed on the isolating layer, the active layer having a surface. A first set of contacts is disposed in contact with the surface along a first axis, and a second set of contacts is disposed in contact with the surface along a second axis transverse to the first axis. An insulating layer is disposed on the surface. A metal control field plate is disposed on the insulating layer and is coupleable to a voltage source to control the accumulation of charge carriers at the surface of the active layer to vary the resistance of the active layer. Also, a method is provided for reducing null offset in a Hall-effect element. The method includes the steps of providing an isolating layer, disposing an active layer of a first electrical conductivity type on the isolating layer, the active layer having a surface, disposing a first set of contacts on the surface along a first axis, disposing a second set of contacts on the surface along a second axis transverse to the first axis; and disposing an insulating layer on the surface. A voltage is applied across the insulating layer to control the accumulation of charge carriers at the surface to vary the resistance of the active layer.
