Abstract: Embodiments relate to stress sensors and methods of sensing stress. In an embodiment, a stress sensor comprises a vertical resistor. The vertical resistor can comprise, for example, an n-type resistor and can have various operating modes. The various operating modes can depend on a coupling configuration of terminals of the resistor and can provide varying piezo-coefficients with very similar temperature coefficients of resistances. Comparisons of resistances and piezo-coefficients in differing operating modes can provide a measure of mechanical stresses acting on the device.

Abstract: A resistive element includes a resistive region in a semiconductor substrate, a first contact structure and a second contact structure. The semiconductor substrate includes a first main surface area. The resistive region extends in a lateral direction parallel to the main surface area and in a vertical direction perpendicular to the main surface area, and includes a first piezo-resistive coefficient for a current flow in the lateral direction and a second piezo-resistive coefficient for a current flow in the vertical direction. The first contact structure contacts a portion of a first face of the resistive region and the second contact structure contacts a portion of a second face of the resistive region. The resistive element generates a current flow distribution within the resistive region having a lateral component and a vertical component that results in a piezo-resistive coefficient of the resistive element.

Abstract: Embodiments relate to systems and methods for reducing errors in sensor devices and systems. In embodiments, the sensor devices comprise magnetic field sensor devices, such as ordinary or vertical Hall sensor devices, and the error to be reduced is a residual offset error, though in other embodiments other sensor devices can be used and/or other types of errors can be targeted for reduction or elimination. In one embodiment, at least two such sensor devices not electrically coupled with one another are sequentially operated in a spinning current-type mode such that an individual output signal from each of the at least two sensor devices is obtained. A total output signal can then be calculated, such as by averaging or otherwise combining the individual output signals from each sensor device.
