Abstract
In order to further develop a magnetoresistive sensor device () comprising at least one substrate or wafer (), in particular at least one silicon wafer, and at least one sensing element (), in particular at least one A[nisotropic]M[agneto]R[esistive] sensing element and/or—at least one G[iant]M[agneto]R[esistive] sensing element, for example at least one multilayer G[iant]M[agneto]R[esistive] sensing element, said sensing element () being arranged on and/or under the substrate or wafer (), as well as a corresponding method of fabricating such magnetoresistive sensor device () in such way that an external or extra bias magnetic field to preset the sensing element () and/or the magnetoresistive sensor device () can be dispensed with, it is proposed to arrange at least one magnetic layer () on () and/or under () the substrate or wafer () and at least partially on () and/or under () the sensing element (), said magnetic layer () providing at least one bias magnetic field.
