title = "Eradication of asymmetric spurious modes in AlN MEMS resonators using mode conversion",
abstract = "This papers reports on a spurious mode suppression technique that converts the asymmetrical (A0) mode to the intended symmetrical (S0) mode vibrations by installing a notch in aluminum nitride (AlN) laterally vibrating resonators. The technique has been experimentally validated to simultaneously eradicate the A0 spurious mode and enhance the S0 mode electromechanical coupling (kt2) for the monolithically integrated resonators over a wide frequency range (100∼600 MHz). The method described herein has overcome a major bottleneck obstructing the deployment of single-chip multi-frequency AlN resonators as a commercially viable solution for RF front-end filtering. It is also the first demonstration of complete A0 mode suppression in lamb-wave resonators with enhancement of kt2.",
