A vertical Hall device includes a Hall effect region formed in a substrate and a sequence of at least six contacts arranged in or at a surface of the Hall effect region between a first contact and a last contact. The vertical Hall device also includes a first contact interconnection connecting the first contact with a third to the last contact. A vertical Hall device further includes a second contact interconnection connecting a third contact with the last contact. Further embodiments made to a sensing method for sensing a magnetic field parallel to a surface of a substrate.
