Claim 0:
1. An apparatus, comprising:
a semiconductor die comprising a Hall sensor arranged in a first plane that is parallel to a device side surface of the semiconductor die;
a passivated magnetic concentrator comprising a magnetic alloy layer formed over the device side surface of the semiconductor die having an upper surface facing away from the device side surface of the semiconductor die, the upper surface of the magnetic alloy layer covered by a layer of polymer material, wherein the device side surface of the semiconductor die includes an area uncovered by a footprint of the layer of polymer material;
a backside surface of the semiconductor die opposite the device side surface mounted to a die side surface of a die pad on a package substrate, the semiconductor die having bond pads on the device side surface spaced from the passivated magnetic concentrator;
electrical connections coupling the bond pads of the semiconductor die to leads of the package substrate; and
a mold compound covering the passivated magnetic concentrator, the semiconductor die, the electrical connections, a portion of the leads, and the die side surface of the die pad.
