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 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.

Abstract: The invention concerns an assembly comprising a piezoelectric resonator (14) and a case (10), the case including a base part (11), on which the resonator is mounted, a wall (12) extending from said base part so as to surround at least partially said resonator, and a cover fixed to said wall in such a way as to close said case. The base part includes a main portion (17) and at least two conductive vias (16a, 16b). The conductive vias electrically connect The piezoelectric resonator to an outside circuit through the base part, and each of the conductive vias is surrounded by a insulating lining (18) so as to insulate the vias from the main portion (17).
