    摘要: A micromechanical component placed on a substrate face includes at least one cell. A counter-electrode of a cell capacitor is placed under a cavity. The counter-electrode can be made from a first part of a lower conductive layer. An optionally circular membrane used as an electrode of the capacitor is placed above the cavity. The membrane is homogeneous, has a substantially uniform thickness, and can be part of an upper conductive layer preferably supported by a second part of the lower conductive layer. A caustic channel used to remove the sacrificial coating in order to form the cavity is laterally connected thereto. The channel has a vertical dimension equal to the vertical dimension of the cavity. A closure is adjacent to the channel and disposed outside the membrane. The component can be used as a pressure sensor, and can have several cells each adjacent to six other cells. A process for fabricating a micromechanical component is also provided.

    摘要: Etching openings are provided in a membrane above an etched-out cavity, only at a distance of at most one tenth of the diameter of the member away from the edge of the cavity. For production, a poly layer is applied to a sacrificial layer composed of SiO2 and is provided with rows of etching holes, through which channels are etched out in the sacrificial layer. The poly layer is oxidized and is made smooth by means of a planarization layer. Etching holes are produced in the edge region of the membrane layer. The sacrificial layer is removed over the entire area of the cavity which is to be produced, with the etching medium propagating sufficiently quickly through the channels.

    摘要: An integrated sensor is fabricated by etching recesses or depressions into the top side of a semiconductor body and by fabricating sensor components in the recesses or depressions. The sensor components are lowered in the recesses or depressions by approximately half of their height. Electronic components are fabricated in the remaining regions of the top side of the semiconductor body. The remaining regions may be covered with a protective layer if the recesses or depressions are fabricated after the electronic components.

    摘要: 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.
