Patent number: 8110119Abstract: 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: GrantFiled: April 18, 2008Date of Patent: February 7, 2012Assignee: International Business Machines CorporationInventors: Marcus Breuer, Guenther Crolly, Michael Haag, Manfred Jung, Thorsten Muehge, Johannes Paul, Joerg Sauerwein, Rolf Schaefer, Alexandra Welzel

Patent number: 7710113Abstract: A method, a magnetic field sensor, and an electronic device measure and determine the magnitude and/or the direction of a magnetic field. The magnetic sensor is based on at least a first magnetoresistive-layered structure having an electric resistance depending on the magnitude of the magnetic field. The magnetic sensor generates at least a first offset magnetic field. The magnitude and the direction of the offset magnetic field can be modified to compensate the magnetic field. The electric resistance of the magnetoresistive-layered structure depends on the superposition of magnetic field and offset magnetic field. A maximum electric resistance indicates that the magnetic field is compensated by the offset magnetic field. In this case the magnitude of the magnetic field corresponds to the magnitude of the offset magnetic field, and the direction of the magnetic field is given by the reversed direction of the offset magnetic field.Type: GrantFiled: April 21, 2007Date of Patent: May 4, 2010Assignee: International Business Machines CorporationInventors: Guenther Crolly, Thorsten Muehge, Rolf Schaefer, Ernst-Dieter Weissenberger
