This paper reports the high temperature characteristics of AlN film SAW sensor integrated with TC4 alloy substrate. The AlN films were directly sputtered on the TC4 metal substrate. SAW resonators were fabricated on the AlN films/TC4 structure by lift-off photolithography techniques. X-ray diffraction measurement shows that the AlN film is highly c-axis oriented. To explore the temperature behavior of the layered AlN/TC4 SAW devices, the samples with different thicknesses of AlN film were prepared and measured at different temperature. The results show that the resonance frequency of the AlN film SAW device decreases with increasing temperature. The dependence of temperature behaviors of the devices on the thickness of AlN films are also presented and discussed. The absolute value of temperature coefficient of frequency decreases from 89.4 ppm/°C to 66.2 ppm/°C, when the thickness of AlN film increases from 1.5 μm to 3.0 μm. From room temperature to 350 °C, the electromechanical coupling coefficient ( K 2 ) of the devices increases by about 30%. The thermal hysteresis errors of the SAW devices are less than 3.87%. The prepared AlN film SAW sensor integrated with TC4 alloy has great potential applications in high temperature harsh environment.

High temperature characteristics of langasite surface acoustic wave (SAW) devices coated with an AlN thin film have been investigated in this work. The AlN films were deposited on the prepared SAW devices by mid-frequency magnetron sputtering. The SAW devices coated with AlN films were measured from room temperature to 600 °C. The results show that the SAW devices can work up to 600 °C. The AlN coating layer can protect and improve the performance of the SAW devices at high temperature. The SAW velocity increases with increasing AlN coating layer thickness. The temperature coefficients of frequency (TCF) of the prepared SAW devices decrease with increasing thickness of AlN coating layers, while the electromechanical coupling coefficient (K2) of the SAW devices increases with increasing AlN film thickness. The K2 of the SAW devices increases by about 20% from room temperature to 600 °C. The results suggest that AlN coating layer can not only protect the SAW devices from environmental contamination, but also improve the K2 of the SAW devices.
