Abstract
Magnetically sensitive semiconductor elements suitable for fabrication in monolithic integrated circuits are disclosed. The elements comprise a semiconductor region of one conductivity type with contact means for providing current flow generally parallel to a major axis, a second orthogonal axis for the application of a magnetic field, and yet a third mutually orthogonal axis along which are disposed at least three second type conductivity regions forming in combination with the first major region a transistor structure with differential properties. In some of the embodiments, low magnetic offset is provided by a selfaligning feature, and power comsumption is minimized by a high resistance region in the device.
