    Abstract: A semiconductor component with passivation includes at least two double passivating layers, of which an uppermost is applied to a planar surface of a layer located therebelow. The double passivating layers include two layers of different dielectric materials, for example silicon oxide and silicon nitride. The respective thicknesses of the individual passivating layers can be adapted to dimensions of the structuring of the layer to which the passivation is applied. This produces a reliable passivation which is particularly suitable for capacitively measuring fingerprint sensors.

    Abstract: Rotation rate sensor as a micromechanical component in silicon, in which a ring with a rigid strut along a diameter is so suspended at elastic braces and anchoring arrangements on a substrate as to be able to perform rotation oscillations about its center axis and to be able to be tilted about the strut under the influence of outer torques. There are electrodes present at the ring and at the substrate, at which electrodes electrical voltages can be applied such that rotary oscillations of the ring about its center axis can be excited and rotary oscillations about the strut can be detected. To stabilize the position of the ring in the neutral position, additional electrodes can be provided at the ring and at the substrate for the generation of electrostatic forces.

    Abstract: An acceleration sensor is produced on a silicon substrate by etching to leave a cantilevered beam of polysilicon with a tip on the substrate projecting toward this beam. Acceleration of the sensor causes the beam to bend, thereby changing the spacing between the tip and the beam, and thereby also changing the tunnel current, which is measured. Electrodes are provided that, given application of a potential thereto, effect an electrostatic compensation of the bending of the beam.

    Abstract: In a relative pressure sensor or miniaturized microphone as a micromechanical sensor component, a polysilicon membrane is arranged over a polysilicon membrane of an SOI substrate. A recess that is connected to the cavity between the membrane and the body silicon layer by openings in the body silicon layer is present in the substrate on the back side. Given an excursion of the membrane, a pressure equalization can therefore occur in the cavity as a result of these openings. The measurement occurs capacitatively by electrical connection of the electrically conductively doped membrane and a doped region formed in the body silicon layer.
