Researchers Submit Patent Application, "Acoustic Resonator Assembly And Filter", for Approval (USPTO 20230327643).

"In some embodiments, at least two vertically connected acoustic resonators are bonded to each other through a bonding layer arranged on the support layer, and after two acoustic resonators are bonded to each other, a distance between a top electrode layer of one acoustic resonator and a top electrode layer of the other acoustic resonator ranges from 10 mm to 20 mm in the active area. The acoustic resonator assembly according to claim 1, wherein at least two vertically connected acoustic resonators are bonded to each other through a bonding layer arranged on the support layer, and after two acoustic resonators are bonded to each other, a distance between a top electrode layer of one acoustic resonator and a top electrode layer of the other acoustic resonator ranges from 10 mm to 20 mm in the active area. The acoustic resonator assembly according to claim 1, wherein electrodes of the acoustic resonator and electrodes of another acoustic resonator are connected to each other in a plurality of ways, to form at least one of a series structure and a parallel structure. "In some embodiments, bottom electrode layers of acoustic resonators of two adjacent acoustic resonator assemblies arranged side by side are arranged on one layer, and connected to each other.
