Abstract: Micromachined ultrasonic transducers integrated with complementary metal oxide semiconductor (CMOS) substrates are described, as well as methods of fabricating such devices. Fabrication may involve two separate wafer bonding steps. Wafer bonding may be used to fabricate sealed cavities (306) in a substrate (302). Wafer bonding may also be used to bond the substrate (302) to another substrate (304), such as a CMOS wafer. At least the second wafer bonding may be performed at a low temperature.

Abstract: Aspects of the technology described herein relate to ultrasound device circuitry as may form part of a single substrate ultrasound device having integrated ultrasonic transmission units, a delay mesh circuitry integrated with the substrate, coupled to inputs of the plurality of ultrasound transmission units and configured to output to the plurality of ultrasound transmission units a plurality of time-delayed versions of a delay mesh circuitry input signal corresponding to a waveform generated by a waveform generator.

Abstract: Apparatus and methods are described that include ultrasound imaging devices, which may operate in a transmissive ultrasound imaging modality, and which may be used to detect properties of interest of a subject such as index of refraction, density and/or speed of sound. Devices suitable for performing high intensity focused ultrasound (HIFU), as well as HIFU and ultrasound imaging, are also described.
