Abstract

A method for redundantly measuring a magnetic field for a sensor arrangement including a carrier having a first side and a second side, a first sensor disposed on a first semiconductor substrate on the first side of the carrier, and a second sensor disposed on a second semiconductor substrate on the second side of the carrier, the method including: sensing a component of a magnetic field perpendicular to the carrier with the first sensor and sensing the same component of the magnetic field perpendicular to the carrier with the second sensor.
