Abstract:
A method of micromechanically manufacturing a layered fixed electrode and a layered movable electrode of a semiconductor element, which are exposed over a substrate, over a certain area, comprising:removing a sacrificial layer by etching to expose the fixed electrode and the movable electrode with respect to the substrate; wherein: the sacrificial layer is arranged between the substrate and the fixed electrode and the movable electrode, the substrate being on a first side on the sacrificial layer, and the fixed electrode and the moveable electrode being on a second side of the sacrificial layer, the first side being a side opposite the second side; and a first thickness of the sacrificial layer located in a first area of the fixed electrode is less than a second thickness of the sacrificial layer located in a second area of the movable electrode.
