Claim 9:
10. An apparatus, comprising:
a semiconductor die including at least one Hall sensor formed within the semiconductor die, the at least one Hall sensor arranged along a first plane that is parallel to a device side surface of the semiconductor die; and
a passivated magnetic concentrator over the device side surface of the semiconductor die and over the at least one Hall sensor, the passivated magnetic concentrator comprising a magnetic alloy layer and a layer of polymer material over at least an upper surface of the magnetic alloy layer, the upper surface of the magnetic alloy layer facing away from the device side surface of the semiconductor die, wherein the device side surface of the semiconductor die includes an area uncovered by a footprint of the layer of polymer material.
