A resistor bridge of the first sensor unit can include a plurality of magnetoresistors, each having at least one strip of anisotropic magnetoresistive material with a longitudinal axis substantially parallel to the technological anisotropy axis of the material. A resistor bridge of the second sensor unit can include a plurality of magnetoresistors having a plurality of strips of the anisotropic magnetoresistive material, the plurality of strips including a first subset having longitudinal axes aligned at a first angle to the technological anisotropy axis and a second subset having longitudinal axes aligned at a second angle to the technological anisotropy axis.

The strip of horizontal magnetoresistive layer is disposed above a surface of a substrate and has a first side and a second side opposite the first side along its extending direction. The conductive part is disposed above or below the horizontal magnetoresistive layer and electrically coupled to the horizontal magnetoresistive layer. The conductive part and the horizontal magnetoresistive layer together form at least an electrical current path. The first magnetic-field-sensing layer is not parallel to the surface of the substrate and magnetically coupled to the horizontal magnetoresistive layer at the first side of the horizontal magnetoresistive layer.

Abstract: A magnetoresistive element formed by a strip of magnetoresistive material which extends on a substrate of semiconductor material having an upper surface. The strip comprises at least one planar portion which extends parallel to the upper surface, and at least one transverse portion which extends in a direction transverse to the upper surface. The transverse portion is formed on a transverse wall of a dig. By providing a number of magnetoresistive elements perpendicular to one another it is possible to obtain an electronic compass that is insensitive to oscillations with respect to the horizontal plane parallel to the surface of the Earth.

Abstract: Embodiments relate to xMR sensors having very high shape anisotropy. Embodiments also relate to novel structuring processes of xMR stacks to achieve very high shape anisotropies without chemically affecting the performance relevant magnetic field sensitive layer system while also providing comparatively uniform structure widths over a wafer, down to about 100 nm in embodiments. Embodiments can also provide xMR stacks having side walls of the performance relevant free layer system that are smooth and/or of a defined lateral geometry which is important for achieving a homogeneous magnetic behavior over the wafer.
