Claim Text:
1. A vertical Hall device comprising: a first Hall effect region and a second Hall effect region different from the first Hall effect region, both Hall effect regions in a common semiconductor body, the first Hall effect region and the second Hall effect region having a main face and an opposite face, respectively; a highly conductive opposite face node in common ohmic contact to the opposite face of the first Hall effect region and to the opposite face of the second Hall effect region in the semiconductor body; a first pair of contacts in or at the main face of the first Hall effect region; and a second pair of contacts in or at the main face of the second Hall effect region, wherein a convex circumscribing contour of the second pair of contacts is disjoint from a convex circumscribing contour of the first pair of contacts, in that a straight line between any two points within the contacts of the first pair of contacts does not contain any point within the contacts of the second pair of contacts, and a straight line between any two points within the contacts of the second pair of contacts does not contain any point within the contacts of the first pair of contacts.
