    Abstract: A device includes a semiconductor substrate, and a capacitive sensor having a back-plate, wherein the back-plate forms a first capacitor plate of the capacitive sensor. The back-plate is a portion of the semiconductor substrate. A conductive membrane is spaced apart from the semiconductor substrate by an air-gap. A capacitance of the capacitive sensor is configured to change in response to a movement of the polysilicon membrane.
