Abstract: Apparatus and associated methods may relate to Magneto-Resistive Sensing Devices (MRSDs). In accordance with an exemplary embodiment, an MRSD comprises an underlying semiconductor device and a magneto-resistive sensor. In some exemplary embodiments, the semiconductor device is processed through most of a standard process flow. After the standard process flow, in various embodiments, a planarization step may be performed to create a more planar top surface. In some embodiments, the magneto-resistive material, which may be made from a Nickel-Iron alloy, called Permalloy, is deposited on the planar surface. A layer of interconnect metallization also may reside in this top region. The magneto-resistive material may contact the topmost layer of metallization of the semiconductor device via contact openings in the planarized surface. In some embodiments, the magneto-resistive material may similarly contact the topmost layer of metallization through these contact openings.
