Abstract
Official abstract text for this publication.
A vertical Hall device indicative of a magnetic field parallel to a surface of a substrate comprises first, second, third and fourth terminals. The vertical Hall device further comprises contacts to generate a Hall effect signal indicative of the magnetic field. At least one pair of Hall effect regions is provided which comprises a first Hall effect region and a second Hall effect region formed in the substrate. A first group of the contacts is arranged in or at a surface of the first Hall effect region, the first group comprising a first and second outmost contacts. A second group of contacts is arranged in or at a surface of the second Hall effect region, the second group comprising third and fourth outmost contacts. Each of the first, second, third and fourth terminals is connected to a same number of outmost contacts.
First claim
