Patent abstract
An electronic device comprises a CMOS substrate having a first surface and a second surface opposite the first surface. A plurality of ultrasonic transducers is provided having a transmit/receive surface. A contact surface is piezoelectrically associated with the plurality of ultrasonic transducers and is formed on the first surface of the CMOS substrate. The plurality of ultrasonic transducers is disposed on the second surface of the CMOS substrate, with the transmit/receive side attached to the second surface thereof such that the CMOS substrate is between the plurality of ultrasonic transducers and the platen. An image sensing system is also provided, together with a method for ultrasonic sensing in the electronic device.
