Abstract
The present application provides a film bulk acoustic resonator, including a substrate, an acoustic reflection structure arranged on one side of the substrate, a bottom electrode stacked on one side of the acoustic reflection structure, a piezoelectric film covered on the bottom electrode and a top electrode stacked on a side of the piezoelectric film away from the bottom electrode. An interdigital protrusion frame is provided on a side of the top electrode away from the piezoelectric film, and the interdigital protrusion frame includes a first protrusion frame and a second protrusion frame arranged at intervals. The first protrusion frame and the second protrusion frame respectively extend toward each other and overlap each other to form at least a pair of interdigital structures, and each of the interdigital structures includes two forks spaced apart by a preset distance along an overlapping direction.
