  • Barber pole structure for magnetoresistive sensors and method of forming same
    Patent number: 6850057
    Abstract: A method of making a magnetorestrictive sensor involves the deposition of a magnetorestrictive strip over a substrate, the deposition of an insulating layer over the magnetorestrictive strip, the etching of barber pole windows through the insulating layer, the deposition of a conductive material over the insulating layer and into the barber windows, and the etching away of the conductive material between the barber pole windows so as to form barber poles. In this manner, the formation of the barber poles is controlled by the windows formed in the insulating layer.
