Abstract
A vertical Hall device has a deep N-well, two inner contacts, two outer contacts and, optionally, a central contact disposed at a surface of the deep N-well and arranged along a straight symmetry line. The vertical Hall device is designed according to the invention to have an effective width of the outer contacts that is bigger than an effective width of the inner contacts. A shallow highly doped Pstripe may be disposed between the inner contacts or between each of the inner contacts and the central contact. These measures help to balance the resistances of the Wheatstone bridge which describes the electrical characteristics of the vertical Hall device.
