“…Surface acoustic wave (SAW) devices have been widely used in various applications and have several advantages: (a) extremely high sensitivity, (b) high SNR value, (c) small size, (d) wide operating frequency range (10 MHz to 1 GHz), and (e) ease of integration with planar processing technology. Because of these advantages, SAW technology is often applied in the fabrication of various electronics devices such as RF filters and sensors (1)(2)(3)(4).…”

We present the results of a basic study on surface acoustic wave (SAW) propagation characteristics with electrochemical deposition of Ge thin films for functional devices. We investigated forming Ge film on the SAW propagation path by using electrochemical deposition as a new process approach. Energy-dispersive X-ray spectroscopy (EDX) analysis of deposited particles indicated that the electrochemical deposition of Ge was successfully achieved by applying pulse-potential to the working electrode. The experimental results of the fabricated device show that the SAW propagation characteristics of LiNbO 3 with Ge has a frequency shift toward a higher range due to the change in the mass-loading of SAW propagation after Ge deposition. These experimental results indicate the potential use for functional devices.

A coupling-of-modes (COM) analysis is given for the film thickness dependence of a single-phase undirectional transducer (SPUDT), while the finite-element method (FEM) is employed for evaluating all the coefficients of COM equations. The relationship between the directivity and dispersion curves of the transducer is discussed. The theoretical analysis shows that when the electrode finger thickness increases through a threshold value, a mode conversion phenomenon occurs and the value of the reflection phase changes from the positive to the negative. This result predicts that the forward direction of a film thickness difference type SPUDT will move conversely when the electrode film thickness increases through the threshold thickness. A prototype step-type SPUDT, fabricated on 128 degrees Y-X LiNbO(3) substrate, showed a directivity of 10 dB/transducer at 481.5 MHz, and a low-loss surface acoustic wave (SAW) filter showed a minimum insertion loss of 3.8 dB.
