Abstract: Described herein are methods and apparatuses for packaging an ultrasound-on-a-chip. An ultrasound-on-a-chip may be coupled to a redistribution layer and to an interposer layer. Encapsulation may encapsulate the ultrasound-on-a-chip device and first metal pillars may extend through the encapsulation and electrically couple to the redistribution layer. Second metal pillars may extend through the interposer layer. The interposer layer may include aluminum nitride. The first metal pillars may be electrically coupled to the second metal pillars. A printed circuit board may be coupled to the interposer layer.

Abstract: Micromachined ultrasonic transducers having pressure ports are described. The micromachined ultrasonic transducers may comprise flexible membranes configured to vibrate over a cavity. The cavity may be sealed, in some instances by the membrane itself. A pressure port may provide access to the cavity, and thus control of the cavity pressure. In some embodiments, an ultrasound device including an array of micromachined ultrasonic transducers is provided, with pressure ports for at least some of the ultrasonic transducers. The pressure ports may be used to control pressure across the array.
