These devices are usually created on a Si wafer using integrated circuit (IC), the standard processes and micromachining processes also manufactured sensors, ultrasonic frog skin, going so far as to allow integration with the Sri signal processing circuitry, such as the use of ultrasonic probe using epitaxial. PZT thin film grown on epitaxialPt/Al 2 O 3 Si that has extremely spacious preamplifier circuit impedance and matching. We then prepare a report of multi-layer epitaxial structure that is suitable for the production of the sensor to the surface on Si and evaluate the sensitivity of the ultrasonic sensor, click to give details of the report, the first use of PZT films on structural SrRuO3/Pt/-Al2O3/Si.
