Abstract (en)

[origin: DE19857674C1] A device for testing capacitive measurement sensors includes a carrier i.e. a substrate (1) or a semiconductor body or a semiconductor chip on which are mounted the pads (2) required for the test and preferably the electronic components for controlling and evaluating the measurement results are integrated. A dielectric layer (4) is provided between the surface and the pads. The dielectric layer is made of a material whose dielectric constant (relative permittivity) is so heavily dependent on an electric field present in the material that a measurable change in capacitance takes place, when a potential difference between the pads and the conductors arranged over the surface is varied in order to drive the device.
