Abstract
Three bridge circuits (), each include magnetoresistive sensors coupled as a Wheatstone bridge () to sense a magnetic field () in three orthogonal directions () that are set with a single pinning material deposition and bulk wafer setting procedure. One of the three bridge circuits () includes a first magnetoresistive sensor () comprising a first sensing element () disposed on a pinned layer (), the first sensing element () having first and second edges and first and second sides, and a first flux guide () disposed non-parallel to the first side of the substrate and having an end that is proximate to the first edge and on the first side of the first sensing element (). An optional second flux guide () may be disposed non-parallel to the first side of the substrate and having an end that is proximate to the second edge and the second side of the first sensing element ().
