1. A Hall effect device indicative of a magnetic field, wherein the Hall effect device comprises:

  • a Hall effect region of a first semiconductive type formed in or on top of a substrate, wherein the substrate comprises an isolation arrangement to isolate the Hall effect region in a lateral direction and in a depth direction from the substrate or other electronic devices in the substrate;

    at least three contacts arranged at a top of the Hall effect region to supply the Hall effect device with electric energy and to provide a Hall effect signal indicative of the magnetic field, wherein the Hall effect signal is generated in a portion of the Hall effect region defined by the at least three contacts; and

    a lateral conductive structure of the first semiconductive type located between the Hall effect region and the isolation arrangement, wherein a doping concentration of the lateral conductive structure is higher than a doping concentration of the Hall effect region.
