| Abstract: | This paper described the future trends in piezoelectric and ferroelectric film materials and their applications. Through the progress of film growth technology, new prospects are created in a wide range for integrated solid state devices made of piezoelectric and ferroelectric films. ZnO and A1N films will be widely used for SAW and BAW devices. Specially, more success in device performance has been obtained for film bulk acoustic wave resonators (FBARs) and high overtone bulk acoustic resonators(HBARs). PZT and PLZT epitaxial solid solution films will be used for pyroelectric detectors and SAW devices. It is possible to use ferroelectric films in ferroelectric memories with high Performances and integrated optics fields,but this depends on the successful control of interface structure and properties of multiple films. |
