Firstly, suitable AlN materials will be selected, and the thin films will be prepared on substrates such as glass, quartz or silicon wafer by sputtering or chemical vapor deposition (CVD) and so on. The structure, morphology, and physical properties of AlN thin films will be analyzed and characterized by X-ray diffraction, scanning electron microscopy, and other testing methods. Then, the processed AlN thin film will be made into resonator structures, and the electrical, piezoelectric, and acoustic properties of the resonator will be tested on the testing equipment. The process parameters will be adjusted and the influence on the performance of the resonator will be studied. Finally, the experimental results will be processed and analyzed, and the possibility and approach of improving the performance of AlN thin film cavity acoustic resonator will be explored.Keywords: AlN thin film, cavity acoustic resonator, preparation, performance testing, optimization.
