Abstract

In various embodiments, a Hall sensor arrangement for the redundant measurement of a magnetic field may include a first Hall sensor on a top side of a first semiconductor substrate; a second Hall sensor on a top side of a second semiconductor substrate; a carrier having a top side and an underside; wherein the first Hall sensor is arranged on the top side of the carrier and the second Hall sensor is arranged on the underside of the carrier; and wherein the measuring area of the first Hall sensor projected perpendicularly onto the carrier at least partly overlaps the measuring area of the second Hall sensor projected perpendicularly onto the carrier.
