发明名称 Micromechanical system
摘要 In a micromechanical system having a substrate and an electrode situated over the substrate, the electrode is connected to the substrate via a vertical spring. The vertical spring is sectionally provided in a first conductive layer and sectionally provided in a second conductive layer, the second conductive layer being situated over the first conductive layer and the first conductive layer being situated over the substrate. The electrode is provided in a third conductive layer, which is situated over the second conductive layer.
