    摘要: Manufacturing method for an acceleration sensor on silicon, whereby, following the manufacture of the doped regions required for the electronic function elements, a polysilicon layer is deposited. The polysilicon layer is structured such that a portion of this polysilicon layer forms an electrode (for example, the emitter electrode (9) and the collector electrode (10) of a transistor) and a sensor layer (17) provided as sensor element.

    摘要: An acceleration sensor has a proof mass attached by resilient elements, in the form of micromechanical components, in a monocrystalline silicon layer of an SOI (silicon-on-insulator) substrate, the insulator layer of the substrate being removed under the structure which is susceptible to acceleration, in order to enable free mobility of the micromechanical components. Piezoresistors are provided for detecting movement of the proof mass, the piezoresistors supplying electrical signals to an evaluation circuit.

    摘要: 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.

    摘要: A pressure sensor comprises a matrix of diaphragms of polysilicon which, via a structure of electrical conductors, are arranged at an upper side of a silicon substrate for the determination of their variable electrical capacitance dependent on the pressure stressing. These diaphragms are present in at least two different sizes. Capacitances of these diaphragms of a same size are respectively connected to form a sub-unit such that basic capacitances of these sub-units are of a respectively same size.

    摘要: A grid-like arrangement of membranes of doped polysilicon are mounted on a substrate but are electrically insulated therefrom each membrane extends over a cavity and is joined to the substrate at at least two supporting locations so that they cavity lies between the membrane and the substrate. Changes in an electrical quantity existing between the membranes and the substrate are measured as forces exerted on the grid-like arrangement of sensor elements so that the ridges in the skin on a finger tip may be sensed for detecting a fingerprint.

    摘要: Micromechanical component, wherein there are present, between a movable part (2) and a substrate (1), narrowly bounded spikes or spacers (3) which are composed of dielectric and which prevent the movable part from adhering (sticking) to the opposite surface during production and while the component is being operated during deflection in the direction of the substrate. Said spikes are produced by etching an auxiliary layer between the substrate and the structural layer (2) through etching apertures (4) to such an extent that only the layer components (3) forming such spikes are left behind.

    摘要: In producing a CMOS circuit, an n-channel MOS transistor and a p-channel MOS transistor are formed in a semiconductor substrate. In situ p-doped, monocrystalline silicon structures are formed by epitaxial growth selectively with respect to insulating material and with respect to n-doped silicon, such silicon structures being suitable as a diffusion source for forming source/drain regions of the p-channel MOS transistor. The source/drain regions of the n-channel MOS transistor are produced beforehand by means of implantation or diffusion. Owing to the selectivity of the epitaxy that is used, it is not necessary to cover the n-doped source/drain regions of the n-channel MOS transistor during the production of the p-channel MOS transistor.

The digital circuit additionally has a logic circuit unit, whose input is connected to the signal input terminal and whose output is connected to the signal output terminal via a switching element. Furthermore, it has a filter unit, whose input is connected to the signal input terminal and whose output is connected to a control input of the switching element. The filter unit serves for suppressing glitches on a digital signal present at its input.
