Claim 0:
1. An acoustic resonator assembly, comprising at least two acoustic resonators that are vertically connected to each other,
wherein for each of the at least two acoustic resonators,
an acoustic resonator comprises: an acoustic mirror, a bottom electrode layer, a piezoelectric layer and a top electrode layer that are arranged on a substrate;
an active area of the acoustic resonator is defined by an overlapping area of the acoustic mirror, the bottom electrode layer, the piezoelectric layer and the top electrode layer; and
the acoustic resonator further comprises a support layer, the support layer is arranged on the substrate or the piezoelectric layer on a periphery of a projection of the acoustic mirror on the substrate;
wherein the at least two acoustic resonators are vertically connected to each other through the support layer; and
wherein a top electrode layer or a lead wire connected to the top electrode layer arranged on at least one side of the acoustic resonator and a top electrode layer or a lead wire connected to the top electrode layer arranged on at least one side of the other acoustic resonator corresponding to the side of the acoustic resonator extend to a middle of the two acoustic resonators, and are connected to each other to form a suspended structure.
