Abstract:
1. A magnetoresistive sensor comprising: a substrate; a first insulating layer, formed on the substrate; a plurality of individual first conductor lines, formed at a level of the first insulating layer and in the form of discontinuous layer, and whereby the plurality of individual first conductor lines are separated from one another by the first insulating layer; and a magnetoresistive structure, formed on the first insulating layer and the plurality of individual first conductor lines, and whereby the first insulating layer and the plurality of individual first conductor lines are arranged between the substrate and the magnetoresistive structure, wherein a lengthwise extending direction of the magnetoresistive structure is obliquely intersected with a lengthwise extending direction of each of the plurality of individual first conductor lines, and the plurality of individual first conductor lines are electrically connected and directly in contact with the same magnetoresistive structure and respectively are a single metal layer; wherein the magnetoresistive structure comprises: wherein the plurality of individual first conductor lines are electrically connected and directly in contact with the magnetoresistive layer of the magnetoresistive structure to thereby form barber-pole conductors of the magnetoresistive sensor.
