SAW resonators were patterned on CTGS wafers with different orientations at different propagation angles. Ir was used as a metal without additional adhesion layers. Resonator responses were acquired with a network analyzer. Resonance frequencies of the responses were measured and processed to obtain temperature behavior. For the cut with Euler angles (0, 90°, 0) almost linear behavior was observed...
This work is oriented on the used of effective simulation tools to design high temperature SAW sensor. Physical constants of platinum and LGS and related temperature coefficients recently determined were implemented in FEM/SDA program. Plessky's parameters of the Pt/LGS structure were extracted for various temperatures and injected in COM software to calculate frequency response of SAW devices. A...
