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.
