Abstract:
An example embodiment may include a sensor for monitoring and/or measuring stress in a semiconductor component. The component may include a substrate formed of a semiconductor material. The substrate may include a planar main surface. The sensor may include at least one slanted surface of the substrate material, the slanted surface being defined by an oblique inclination angle with respect to the main surface of the substrate. The sensor may also include at least one straight resistive path extending on at least part of the slanted surface and a plurality of contacts and terminals for accessing the at least one resistive path. The contacts and terminals may allow for the measurement of an electrical resistance of the resistive path and an assessment of a shear stress in a plane that is not parallel to the main surface of the substrate.
