Abstract:
1. A micromechanical component, comprising: a conductive substrate; a first conductive layer that is provided above the substrate and forms, above a cavity provided in the substrate, an elastically deflectable diaphragm region of monocrystalline silicon and an adjacent peripheral region; a circuit trace level that is provided above the first conductive layer in a manner electrically insulated from the first conductive layer, the circuit trace level having above the diaphragm region a first electrode region, and having above the peripheral region, a connection region which is connected to the same in an electric manner; and a second conductive layer provided above the circuit trace level, the second conductive layer having above the diaphragm region a second electrode region that is electrically insulated from the first electrode region, and having above the peripheral region a second connection region that is electrically insulated from the second electrode region and that is electrically connected to the first connection region; wherein the first conductive layer is produced out of monocrystalline silicon and the second conductive layer is produced out of polycrystalline silicon; wherein a lattice structure of monocrystalline silicon is provided above the cavity between the substrate and the first conductive layer; and wherein at least one of the second electrode region and the second connection region have feed-through regions that are routed through the substrate to the side of the substrate opposite the diaphragm region in an electrically insulated manner, and are connected to electric contact surfaces.
