  • Method of manufacturing a magnetic sensor with tilted magnetoresistive structures
    Patent number: 8110119
    Abstract: A method of manufacturing a magnetic field sensor device in one embodiment includes applying a mask on a substrate, performing a wet etching procedure on the substrate for generating at least a first groove having tilted side walls, and depositing at least one layer of magnetoresistive material onto a section of the surface of at least a first tilted side wall of the groove. A method of manufacturing a magnetic field sensor device on a substrate having a plurality of tilted planar sections, each of the tilted planar sections having a surface normal angled with respect to a surface normal of the substrate is also provided.
    Type: Grant
    Filed: April 18, 2008
    Date of Patent: February 7, 2012
    Assignee: International Business Machines Corporation
    Inventors: Marcus Breuer, Guenther Crolly, Michael Haag, Manfred Jung, Thorsten Muehge, Johannes Paul, Joerg Sauerwein, Rolf Schaefer, Alexandra Welzel
  • Magnetic sensor with tilted magnetoresistive structures
    Patent number: 7492554
    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.
