Abstract
Disclosed are a Cartesian curve configuration-based bulk acoustic wave resonator and a bulk acoustic wave filter, belonging to the technical field of resonators. The Cartesian curve configuration-based bulk acoustic wave resonator includes a substrate, a support layer, a bottom electrode, a piezoelectric layer, and a top electrode stacked sequentially, with a cavity disposed between the substrate and the support layer. Contour shapes of overlapping portions of the bottom electrode and the piezoelectric layer and of overlapping portions of the piezoelectric layer and the top electrode are both symmetrical closed figures and the closed figure is comprised of at least one Cartesian curve. The Cartesian curve configuration-based bulk acoustic wave resonator according to the present disclosure allows the resonator to generate fewer vibration nodes, thereby reducing energy loss and greatly improving the performance of the resonator.
