Abstract:
A semiconductor component includes a semiconductor body of a first conductivity type which accommodates a space charge region. Semiconductor regions of a second conductivity type are disposed in at least one plane extending essentially perpendicularly to a connecting line extending between two electrodes. A cell array is disposed under one of the electrodes in the semiconductor body. At least some of the semiconductor regions of the second conductivity type are connected to the cell array via filiform semiconductor zones of the second conductivity type in order to expedite switching processes. A method for fabricating such a semiconductor component is also provided.
Abstract:
The invention concerns a device for mechanically regulating an electrical capacitance. Said device comprises a first electrode structure (10) including first (16) and second (24) surfaces, the first surface (16) having at least a projecting portion (18a 18d). The device also comprises a second electrode structure (12), spaced apart from the first electrode structure (10) and including at least a recess (20a 20d) arranged in such a way that the projecting portion(s) (18a 18d) of the first electrode structure (10) project(s) into said recess, an electrical capacitance being determined between the opposite surface zones of the first (10) and of the second (12) electrode structures. A third electrode structure (14) for regulating the electrical capacitance is arranged between the first (10) and the second (12) electrode structures . Said third electrode structure (14) is spaced apart from the first electrode structure (10) and located opposite said second surface (24). The first electrode structure (10) is configured to be freely mobile relative to the second (12) and third (14) electrode structures. Thus, when an electric voltage is applied between the first (10) and the third (14) electrode structures, the electrical capacitance can be regulated, by modifying the distance separating the first (10) and the second (12) electrode structures.
Abstract:
The invention relates to a micromechanical sensor comprising electrodes (1, 2) which are arranged on a substrate, and comprising electrode bars (A) made of silicon that can move with regard to the electrodes. A deformation of the substrate is measured by determining the differential changes in capacity of these electrode bars in comparison to the adjacently arranged electrodes. Two groups of electrode bars are preferably used which are interlocked with one another in an alternating comb-like manner, which, separate from one another, are interconnected at the ends thereof in an electrically conductive manner, and which are anchored on the substrate.

Abstract:
Sensor comprises a MIS transistor with first (S11) and second (S12) drain source regions with a channel region between the two. The first MIS transistor is controlled using a gate electrode (G1/G2) that is arranged so that it can be moved relative to the channel region. The distance variation between channel region and gate electrodes is caused by acceleration and is used to measure it. An Independent claim is made for a method for manufacturing a micromechanical acceleration sensor using MIS transistors.
