Abstract
One embodiment of the present invention relates to a vertical Hall-effect device. The device includes at least two supply terminals arranged to supply electrical energy to the first Hall-effect region; and at least one Hall signal terminal arranged to provide a first Hall signal from the first Hall-effect region. The first Hall signal is indicative of a magnetic field which is parallel to the surface of the semiconductor substrate and which acts on the first Hall-effect region. One or more of the at least two supply terminals or one or more of the at least one Hall signal terminal comprises a force contact and a sense contact.
