摘要： Aspects of the technology described herein relate to an ultrasound device including a first die that includes an ultrasonic transducer, a first application-specific integrated circuit (ASIC) that is bonded to the first die and includes a pulser, and a second ASIC in communication with the second ASIC that includes integrated digital receive circuitry. In some embodiments, the first ASIC may be bonded to the second ASIC and the second ASIC may include analog processing circuitry and an analog-to-digital converter. In such embodiments, the second ASIC may include a through-silicon via (TSV) facilitating communication between the first ASIC and the second ASIC. In some embodiments, SERDES circuitry facilitates communication between the first ASIC and the second ASIC and the first ASIC includes analog processing circuitry and an analog-to-digital converter. In some embodiments, the technology node of the first ASIC is different from the technology node of the second ASIC.

摘要： 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 in a substrate. Wafer bonding may also be used to bond the substrate to another substrate, such as a CMOS wafer. At least the second wafer bonding may be performed at a low temperature.

摘要： A processing device is coupled to a single ultrasound device having a single array of capacitive micromachined ultrasound transducers (CMUTs). The processing device generates a graphical user interface (GUI) having user selectable GUI menu options corresponding to respective ultrasound operating modes for the single ultrasound device having the single ultrasound transducer array. The user-selectable GUI menu options include GUI menu options labeled as representing an ultrasound operating mode for musculoskeletal imaging, breast imaging, carotid imaging, vascular imaging, and abdominal imaging, respectively. The processing device further receives, via the GUI, user input indicating selection of one of the ultrasound operating modes, and in response to receiving the user input, provides an indication to the single ultrasound device having the single array of CMUTs to operate in the selected ultrasound operating mode.
