Abstract:
1. A micromechanical component, comprising: a substrate and having a diaphragm pattern, and including: on a first side of the substrate, a sacrificial layer area on a second passivating layer and which is masked by a first passivating layer of a first electrode and by further overlayers; recesses, in the substrate, from a second side of the substrate that lies opposite the first side, that reach all the way to the second passivating layer by at least one etching operation; a fourth passivating layer for the protection of the exposed walls of the substrate; wherein, after a removal of the second and the fourth passivating layer in the regions of the recesses, the sacrificial layer area starting from the second side is removed, wherein process operations provided for the production of diaphragm pattern are compatible only with a circuit that is monolithically integrated into or on the substrate, and wherein the diaphragm pattern and at least a subsection of the substrate are provided as a capacitor system.
