Abstract
The present disclosure concerns a magnetic reader (MR) sensor device for reading magnetic stripes, the MR sensor device comprising a substrate provided on a wafer, a back-end-of-line (BEOL) interconnect layer and a plurality of magneto-resistive sensor elements embedded within the BEOL interconnect layer; the MR sensor device comprising a protective layer having a Vickers hardness of at least 3 GPa. The present disclosure further concerns a method for manufacturing the MR sensor device. The MR sensor device can be brought close to the surface to the magnetic stripe so that the magnetic stripe can be read with an increased resolution.
