Abstract

A magnetic field sensor device comprising a substrate having at least a first tilted planar section having a surface normal at a first angle with respect to a surface normal of the substrate, and at least a first magnetoresistive layered structure positioned at the at least first tilted section. Methods for manufacturing magnetic field sensor devices are also presented.
