Abstract: Described herein are methods and systems useful in the fabrication of ultrasound transducer devices. Fabrication of ultrasound transducer devices can comprise manipulation of components having extremely small cross-sectional thicknesses, which can increase the risk of damage to the components. For example, inadvertent application of forces sufficient to damage such components is a significant risk during fabrication steps. As described herein, the risk of damage to an ultrasound transducer device component having a small cross-sectional thickness, such as an ultrasound microelectromechanical system (MEMS) wafer, can be reduced by partially or completely coating or filling all or a portion of the component with a stabilizing material, for example, prior to subjecting the component to forces associated with manipulation of the component during the fabrication process.

Abstract: A MEMS oscillator, such as a MEMS scanner, has an improved and simplified drive scheme and structure. Drive impulses may be transmitted to an oscillating mass via torque through the support arms. For multi-axis oscillators drive signals for two or more axes may be superimposed by a driver circuit and transmitted to the MEMS oscillator. The oscillator responds in each axis according to its resonance frequency in that axis. The oscillator may be driven resonantly in some or all axes. Improved load distribution results in reduced deformation. A simplified structure offers multi-axis oscillation using a single moving body. Another structure directly drives a plurality of moving bodies. Another structure eliminates actuators from one or more moving bodies, those bodies being driven by their support arms.
