Abstract
The present disclosure relates to a semiconductor structure for a MEMS device. In some embodiments, the structure includes an interlayer dielectric (ILD) region positioned over a substrate. Further the structure includes an inter-metal dielectric region. The IMD region includes a passivation layer overlying a stacked structure. The stacked structure includes dielectric layers and etch stop layers that are stacked in an alternating fashion. Metal wire layers are disposed within the stacked structure of the IMD region. The structure also includes a sensing electrode electrically connected to the IMD region with an electrode extension via. The structure includes a MEMS substrate comprising a MEMS device having a soft mechanical structure positioned adjacent to the sensing electrode.
