    Abstract: A method for fabricating an MEMS device includes providing a first substrate with a central region and a peripheral region, and forming a plurality of first openings in the peripheral region and a plurality of third openings in the central region by etching the first substrate from a front side. The depth of the first openings is larger than the depth of the third openings. The method further includes forming a photosensitive layer on the surfaces of the first openings and the third openings, bonding a second substrate to the front side of the first substrate, and forming a trench by etching the first substrate from a back side using a patterned mask layer as an etch mask. The trench has a concave bottom surface and exposes a portion of the photosensitive layer formed on the bottom surfaces of the first openings and the third openings.

    Abstract: Considerations for selecting capacitive sensors include accuracy, repeatability, long-term stability, ease of calibration, resistance to chemical and physical contaminants, size, packaging, integration options with other sensors and/or electronics, and cost effectiveness. It is beneficial if such sensors are amenable to above-IC integration with associated control/readout circuitry for reduced parasitics and reduced footprint through area sharing. The inventors have established a combined Lorentz force based magnetometer and accelerometer MEMS sensor exploiting a low temperature, above-IC-compatible fabrication process operating without requiring vacuum packaging. By switching an electrical current between two perpendicular directions on the device structure a 2D in-plane magnetic field measurement can be achieved whilst concurrently, the device serves as a 1D accelerometer for out-of-plane acceleration, by switching the current off and by monitoring the structure's capacitive change in response to acceleration. The design can thus separate magnetic and inertial force measurements, utilizing a single compact device.

    Abstract: An optical-microwave-quantum transducer can include a tapered optical fiber configured to transmit and receive optical signals. The optical-microwave-quantum transducer can also include a cantilever that can include an optical cavity that includes a nanophotonic crystal. The optical cavity can be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons emitted from the tapered optical fiber. The cantilever can also include a mechanical coupler that is configured to induce electrical modulation onto a superconducting cavity in response to the mechanical excitation. The mechanical coupler can also be configured to provide mechanical excitation in response to electromagnetic excitation induced by photons from the superconducting cavity. The optical cavity can further be configured to provide electromagnetic excitation that induces optical modulation on the tapered optical fiber in response to the mechanical excitation.
