    摘要: A micromechanical component includes a substrate and a first oxide layer on the substrate, the first oxide layer having an aperture. The component further includes a conductive functional layer, which is provided on the first oxide layer in the region of the aperture, and a metal layer, which is provided on the functional layer, for producing a bond joint. A second oxide layer is provided on lateral faces of the functional layer for insulating the functional layer.

    摘要: A micromechanical sensor and a method for manufacturing same are described. A secure diaphragm restraint, independent of fluctuations in the cavern etching process due to the process technology, and a free design of the diaphragm are made possible by designing a suitable connection of the diaphragm in an oxide layer created by local oxidation. The micromechanical sensor includes, for example, a substrate, an external oxide layer formed in a laterally external area in the substrate, a diaphragm having multiple perforation holes formed in a laterally internal diaphragm area, a cavern etched in the substrate beneath the diaphragm, whereby the diaphragm is suspended in a suspension area of the external oxide layer which tapers toward connecting points of the diaphragm and the diaphragm is situated in its vertical height between a top side and a bottom side of the external oxide layer.
