Abstract

A systematic approach using Taguchi method is proposed for optimization of complementary metal oxide semiconductor microelectromechanical system surface acoustic wave (SAW) resonators. The aim of the present method is to enhance the performance of SAW devices in terms of electromechanical coupling coefficient while reducing the design and development cost. Controllable factors such as a number of transducers, N t , the distance between input and output transducers, L c , and the thickness of the piezoelectric materials, T c have been optimized. L 27 (3 13 ) orthogonal array was chosen to conduct 27 simulations with three level parameters. Time and cost efficient 2D finite element simulations were done using COMSOL Multiphysics TM for two-step analysis Eigen frequency and frequency domain analysis. The orthogonal array, signal to noise ratio, and analysis of variance (ANOVA) were calculated to determine the best settings of the design parameters. The maximum electromechanical coupling coefficient is achieved at the optimal condition of N t = 6; L c =1.6 μm; T c =2.5 μ m with increased performance by 4.68% for κ 2 and 9.62% for G 12 (f) compared to the initial conditions. The interaction between pairs of factors has also been investigated. The Taguchi method reveals that both N t and L c , and the interaction of N t × L c plays crucial roles in optimizing the electroacoustic conversion of the SAW devices. Hence, the experiment shows that the performance of the SAW device has been successfully optimized.
