    Abstract: According to some embodiments, a conducting layer is formed on a first wafer. An insulating layer is formed on a second wafer. The insulating layer includes a cavity and a conducting area may be formed in the second wafer proximate to the cavity. The side of the conducting layer opposite the first wafer is bonded to the side of the insulating layer opposite the second wafer. At least some of the first wafer is then removed, without removing at least some of the conducting layer, to form a conducting diaphragm that is substantially parallel to the second wafer. In this way, an amount of capacitance between the diaphragm and the conducting area may be measured to determine an amount of pressure being applied to the diaphragm.
