Patent ID: 7492554

Claim:
A magnetic field sensor device comprising: a substrate having a first planar section and at least a first tilted planar section, wherein the at least first tilted planar section intersects with the first planar section such that an imaginary line normal to the surface of the first planar section intersects with an imaginary line normal to the surface of the at least first tilted planar section at a first angle; and at least a first magnetoresistive layered structure positioned at the at least first tilted section; and at least a second tilted planar section, wherein the at least second tilted planar section intersects with the first planar section such that an imaginary line normal to the surface of the first planar section intersects with an imaginary line normal to the surface of the at least second tilted planar section at a second angle; and at least a second magnetoresistive layered structure positioned at the at least second tilted section; wherein a line defined alone an intersection of the first tilted planar section and the first planar section is not parallel to a line defined along an intersection of the second tilted planar section and the first planar section.
