    Abstract: A resonator that includes a substrate with a cavity that extends in a principal surface thereof and a vibrating resonator above the principal surface of the substrate and including bottom and top electrodes with a piezoelectric layer disposed therebetween. Moreover, a silicon dioxide layer is provided above the substrate and below the vibrating resonator to cover the cavity of the substrate, and a silicon layer is provided between the silicon dioxide layer and the vibrating resonator. The bottom electrode, the top electrode and the piezoelectric layer of the vibrating resonator each have a thickness configured to accommodate substantially a half wavelength λ/2 of the resonator, and the silicon layer has a thickness that accommodates substantially multiple of the half wavelength λ/2 of the resonator.

    Abstract: A thin film resonator having enhanced performance and a manufacturing method thereof are disclosed. The thin film resonator includes a supporting means, a first electrode, a dielectric layer and a second electrode. The supporting means has several posts and a supporting layer formed on the posts. The first electrode, the dielectric layer and the second electrode are successively formed on the supporting layer. The thin film resonator is exceptionally small and can be highly integrated, and the thickness of the dielectric layer of the resonator can be adjusted to achieve the integration of multiple bands including radio, intermediate and low frequencies. Also, the thin film resonator can minimize interference and has ideal dimensions because of its compact substrate, making the thin film resonator exceptionally small, yet comprising a three-dimensional, floating construction.
