Simulation And Fabrication Of Piezoelectric Mems Resonators

Abstract

This paper presents FEM analyses and fabrication of piezoelectric MEMS resonators. Modal and harmonic analyses were made using Ansys® Workbench. These simulations showed the influence of resonators geometry on their out-of-plane displacement and corresponding resonant frequencies. Piezoelectric resonators were fabricated by standard microfabrication processing compatible with complementary metal-oxide-semiconductor (CMOS) technology.
