  • Method for fabricating a non-volatile semiconductor memory cell with a separate tunnel window
    Patent number: 6645812
    Abstract: A method for producing a non-volatile semiconductor memory cell with a separate tunnel window cell includes the step of forming a tunnel zone in a late implantation step by performing a tunnel implantation with the aid of a tunnel window cell as a mask. The resulting memory cell has a small area requirement and a high number of program/clear cycles.
    Type: Grant
    Filed: December 28, 2001
    Date of Patent: November 11, 2003
    Assignee: Infineon Technologies AG

  • Magnetic field sensor for stable magnetic field measurement over a wide temperature range
    Patent number: 6150811
    Abstract: A magnetic field sensor consists of a cylinder (2) with a core of premagnetized amorphous ferromagnetic metal. The inductance of the coil (2) is controlled by earth magnetic field H.sub.E and forms part of an L.C. oscillator (1). An adjusting device is provided to smooth out fluctuations from a target value in the oscillator frequency caused by the action of the field H.sub.E on the oscillator coil (2). This is done by allowing another adjustable magnetic field to influence the inductance (2) of the oscillator (1): the adjustable magnetic field is generated by a second coil (3) in the form of a compensating coil and the current flux (1) through the second coil (3) is controlled by the adjusting device in such a way that the magnetic field generated by the second coil (3) compensates for the action of the field H.sub.
