The new design increases by a factor larger than 3 the efficiency of the transduction between tilting of the Coriolis frame inside the gyroscope and corresponding stress on the resistive gauges, in turn improving scale-factor, and bringing noise and stability down to record levels for pitch or roll planar silicon micromachined gyroscopes. At the same time, with respect to a former architecture, a comparative analysis of the impact of the new design choices on the dispersion of the mode-split value is carried out. Results demonstrate that the dispersion increases by a negligible amount, from 36 Hz (old design) to 44 Hz (new design).

This is achieved by increasing the cavity height through the use of electrostatic repulsion. Conventional CMUTs based on attractive forces have promising electroacoustic characteristics but limited output pressure, compared to piezoelectric transducers due to the limited motion ranges for CMUTs imposed by the capacitive transduction gap. Therefore, we propose here an electrostatic repulsive CMUT design with three fixed electrodes and one movable electrode that displaces out-of-plane. Simulation results demonstrate the design’s effectiveness in increasing the transducer’s range of motion, thus enhancing transmission sound pressure. Prototypes were fabricated using MEMSCAP’s PolyMUMPs process. Repulsive actuation allows for more than an order of magnitude (11x) improvement in the allowable motion range and therefore an improvement in the acoustic output by a factor up to 25.42 dB. Experimental tests using a vibrometer and an ultrasonic microphone confirm the effectiveness of the proposed approach. The CMUT array operates over a wide band of frequencies from 150 kHz to 650 kHz, which opens the doors for several applications such as ranging, gesture recognition, and non-destructive testing, with the potential for further improvements in ultrasound transmission.

This method selectively etches silicon dioxide (SiO2) over aluminum (Al) in Micro-Electro-Mechanical Systems (MEMS) fabrication, offering an alternative to traditional methods that often damage Al or require expensive setups. Here, we employ H2 SO4’s hygroscopic properties to effectively dehydrate HF, reducing water content and limiting fluoride ion generation, which is the cause for Al etching during SiO2 etching. Experimental results demonstrate an exceptional selectivity ratio exceeding 130,000:1 for SiO2 over Al, confirming the method’s precision and the preservation of Al’s integrity. The etching technique preserves the electrical and mechanical properties of Al films, even after extended exposure to the etchant, and demonstrates its effectiveness in the practical fabrication of back-end-of-line (BEOL) micro-electromechanical switches. By utilizing readily available chemicals, the proposed etching method enhances economic feasibility and accessibility, demonstrating significant advancements in MEMS fabrication.

Capacitive micromachined ultrasonic transducer (CMUT) arrays, providing convenient integration with supporting electronics, are advantageous for implementing such systems. Fabricating 2D CMUT arrays and integrated circuits (ICs) separately and then combining them in the packaging stage provides flexibility in design and integration. The integrated system can be used for beam-steering and electronic focusing in 3D space. Previously, fabrication processes were reported for implementing 2D CMUT arrays on glass substrates with copper through-glass-via (Cu-TGV) interconnects using anodic bonding and silicon through-glass-via (Si-TGV) interconnects using a sacrificial-release process. Both approaches had challenges, such as voids in Cu-vias, microcracks in laser-drilled glass, mechanical stress in CVD nitride layers, and low fill factor due to fabrication limitations. These challenges can be overcome by combining Si-TGV interconnects with an anodic bonding process. We developed a Si-TGV wafer with a backside glass layer to make it compatible with anodic bonding.
