Patent ID: 8742646

Claim:
An ultrasound acoustic assembly comprising: a plurality of ultrasound acoustic arrays, each array comprising an acoustic stack comprising a piezoelectric layer assembled with at least one acoustic impedance dematching layer and with a support layer, wherein the acoustic stack defines a plurality of dicing kerfs and a plurality of acoustic elements, such that the dicing kerfs are formed between neighboring ones of the acoustic elements, and wherein the dicing kerfs extend through the piezoelectric layer and through the acoustic impedance dematching layer(s) but extend only partially through the support layer; a plurality of application specific integrated circuit (ASIC) die, wherein each ultrasound acoustic array is coupled to a respective one of the ASIC die to form a respective acoustic-electric transducer module wherein each of the acoustic arrays comprises an anisotropic electrically conductive adhesive connected to the acoustic elements; and one or more substrates disposed between the ultrasound acoustic arrays and the ASIC die.
