Disclosed are embodiments of a capacitor with inter-digitated vertical plates and a method of forming the capacitor such that the effective gap distance between plates is reduced. This gap width reduction significantly increases the capacitance density of the capacitor. Gap width reduction is accomplished during back end of the line processing by masking connecting points with nodes, by etching the dielectric material from between the vertical plates and by etching a sacrificial material from below the vertical plates. Etching of the dielectric material from between the plates forms air gaps and various techniques can be used to cause the plates to collapse in on these air gaps, once the sacrificial material is removed. Any remaining air gaps can be filled by depositing a second dielectric material (e.g., a high k dielectric), which will further increase the capacitance density and will encapsulate the capacitor in order to make the reduced distance between the vertical plates permanent.

Two optical wavelengths are used to interrogate a fiber optic Fabry-Perot sensor having a moveable diaphragm that changes the width of a gap between two reflective surfaces. By picking the right operating point for the gap, the power output for one wavelength increases as the gap width changes and the power for the other wavelength decreases. A ratio of the difference of the two powers over the sum of the two powers is formed to generate a detected signal independent of power and phase fluctuations in a fiber between signal sources and sensor and between sensor and detector. This ratio, which is called the visibility, has a response proportional to the pressure of acoustic disturbances that move the diaphragm. The push-pull sensor can be used with both TDM and CW fan-out array architectures.
