ABSTRACT:
An array of ultrasonic transducers, where each of the ultrasonic transducers has a matching layer end and a driving layer/individually isolated end. A bump bond connects each one of the ultrasonic transducers to a substrate. A high voltage electrical conductor is connected to at least one driving layer/individually isolated end to provide a drive signal to at least one of the ultrasonic transducers. A conductive/matching layer is disposed to electrically connect each matching layer end. An outer matching layer is connected to the conductive/matching layer. The bump bond is an indium or solder bump bond having a contact area for contact with an ultrasonic transducer less than 20 percent of the driving layer/individually isolated end for the contacted ultrasonic transducer so as to provide mechanical stability while reducing cross talk among the plurality of ultrasonic transducers.
