Abstract

An integrated magnetoresistive sensing device includes a substrate, a magnetoresistive sensing element and a built-in self test (BIST) unit. The substrate comprises a first surface and a second surface opposite to the first surface. The magnetoresistive sensing element is disposed above the first surface and comprises at least a magnetoresistive layer not parallel to the first surface. The BIST unit is disposed above the first surface and comprises at least a conductive part corresponding to the magnetoresistive layer. The conductive part is configured to generate a magnetic field along a direction perpendicular to the first surface. A projection of the conductive part on the first surface does not overlap with a projection of the magnetoresistive layer on the first surface.
