In this thesis, the AlN thin films were deposited on SiO2/Si and GaN/Sapphire substrates respectively for layered structure SAW devices by Helicon sputtering system. Laser ultrasound system was used to measure the acoustic wave velocity of AlN/SiO2/Si layered structure. Frequency response and insertion loss were measured by an HP8510C vector network analyzer to analysis insertion loss, sidelobe and quality factor. The results showed the possibility of incorporating thin films SAW devices with other semiconductor devices.
