Summary: | A micromechanical component for a capacitive sensor device includes first and second electrodes. The first electrode is at least partially formed from a first semiconductor layer and/or metal layer, and at least one inner side of the second electrode facing the first electrode is formed from a second semiconductor layer and/or metal layer. A cavity is between the first and second electrodes. Continuous recesses are structured into the inner side of the second electrode and sealed off with a closure layer. At least one reinforcing layer of the second electrode and at least one contact element which is electrically connected to the first electrode, to the layer of the second electrode which forms the inner side, to at least one printed conductor, and/or to a conductive substrate area, are formed from at least one epi-polysilicon layer. Also described is a micromechanical component manufacturing method for a capacitive sensor device. |
