Patent ID: 8076739

Claim:
A micromechanical component, comprising: a substrate having a front side and a back side, wherein the back side of the substrate defines a back side of the micromechanical component; and a functional pattern located on a front side of the micromechanical component, the functional pattern being electrically contacted to the back side of the substrate in a contact region; wherein: the substrate has at least one contact hole and a plurality of plated-through holes in the contact region, the contact hole extending from the back side of the substrate towards a front side of the micromechanical component, the plurality of plated-through holes coated with an electrically conductive material to connect the contact hole to the front side of the micromechanical component through each of the plated-through holes at a common electric potential; a mechanically stable diaphragm is situated between the contact hole and the front side of the micromechanical component; an epitaxial layer is provided on the front side of the substrate, and the contact hole extends at least up to the epitaxial layer; and between the substrate and the epitaxial layer, an oxide layer is situated at least in the contact region.
