ABSTRACT:
The invention disclosed provides a method and semiconductor device for electrically detecting an inverted magnetic field. A semiconductor magneto-resistive element having two electrodes on opposite ends is disposed in a magnetic field, the magnetic field having at least one inverted magnetic field portion which is applied to one part of the semiconductor element while the normal magnetic field is applied to the other part of the semiconductor element. A current is applied to the two electrodes of the semiconductor element, and measurement of the resistance of the semiconductor device is effected for detecting the inverted magnetic field.
