    Abstract: Matching layers configured for use with ultrasound transducers are disclosed herein. In one embodiment, a transducer stack can include a capacitive micromachined ultrasound transducer (CMUT), an acoustic lens, and a matching layer therebetween. The matching layer can be made from a compliant material (e.g. an elastomer and/or an liquid) and configured for use with CMUTs. The matching layer can include a bottom surface overlying a top surface of the transducer and a top surface underlying a bottom surface of the lens.

    Abstract: A method (70) of forming sensor packages (20) entails providing a sensor wafer (74) having sensors (30) formed on a side (26) positioned within areas (34) delineated by bonding perimeters (36), and providing a controller wafer (82) having control circuitry (42) at one side (38) and bonding perimeters (46) on an opposing side (40). The bonding perimeters (46) of the controller wafer (82) are bonded to corresponding bonding perimeters (36) of the sensor wafer (74) to form a stacked wafer structure (48) in which the control circuitry (42) faces outwardly. The controller wafer (82) is sawn to reveal bond pads (32) on the sensor wafer (74) which are wire bonded to corresponding bond pads (44) formed on the same side (38) of the wafer (82) as the control circuitry (42). The structure (48) is encapsulated in packaging material (62) and is singulated to produce the sensor packages (20).
