Volumetric Imaging Using 2D Capacitive Micromachined Ultrasonic Transducer Arrays (CMUTs): Initial Results

This paper presents the first volumetric images obtained using a 2D CMUT array with throughwafer via interconnects. An 8×16-element portion of a 32×64-element array flip-chip bonded onto a glass fanout chip was used in the experiments. This study experimentally demonstrates that 2D CMUT arrays can be fabricated with high yield using silicon micromachining processes, individual electrical connec...
