Abstract
A CMOS compatible GHz ultrasonic pulse/echo transmit-receive ultrasonic delay element demonstrating less than <6 ppm stability over time and having a zero-temperature coefficient of delay at two temperatures. The delay element includes one or more CMOS compatible piezoelectric transducers requiring no release step, which transmit and/or receive a GHz-ultrasonic wave packet. The bulk substrate exhibits low loss for the GHz-ultrasonic wave packet transmitted through the substrate and uses the phenomenon of diffraction to retrieve multiple reflections.
