摘要： The disclosure relates to micro-electromechanical systems (MEMS) and magnetic MEMS sensors. The sensors include a substrate having a surface, a first magnetic field detector positioned on the surface, a second magnetic field detector positioned on the surface proximate to the first magnetic field detector, and a third magnetic field detector positioned on the surface proximate to the first and second magnetic field detectors. Each of the first, second and third magnetic field detector is capable of detecting external magnetic fields that are mutually orthogonal along three directions. In certain embodiments, the magnetic MEMS sensors may be useful as electronic compasses. The disclosure also relates to fabricating a magnetic MEMS device, such as an electronic compass, from or on a single wafer, which includes multiple MEMS sensors.

摘要： The present invention relates to magnetic micro-electromechanical systems (MEMS) or magnetic MEMS devices, particularly electronic devices in which a member adjoins a base or substrate and extends from the substrate proximate to a magnetic field element having an altered output associated with movement of the member. The first magnetic field element is adapted to emit or detect a magnetic field and positioned proximate to the member, and the second magnetic field element adapted to emit or detect a magnetic field and positioned proximate to the base or substrate, such that movement of the member in a first direction by a non-magnetic force results in a variation of magnetic field strength associated with displacement of the sensor in a first direction. The invention also relates to methods for fabricating magnetic MEMS devices, transducers, sensors, and accelerometers.

摘要： A differential read head comprises one tri-layer reader or a plurality of tri-layer readers operating in a current perpendicular to plane (CPP) mode. The tri-layer readers each comprise a first free layer, a second free layer, and a nonmagnetic layer positioned therebetween. A nonmagnetic spacer means is positioned between the plurality of tri-layer readers for electrically connecting the plurality of tri-layer readers in series such that a single CPP sense current representing a differential signal flows serially through the read head. With a single tri-layer reader, the free layers are spaced by a width substantially similar to the transition width of the magnetic medium.
