Latest Patents

Yao Cai holds a patent for a resonator, filter, and duplexer. This invention relates to the technical field of resonators and includes a substrate, a lower electrode layer, a piezoelectric layer, and an upper electrode layer, which are sequentially formed on the substrate. An acoustic reflection structure is formed on the surface of the substrate that is close to the lower electrode layer. The overlapping region of the acoustic reflection structure, the lower electrode layer, the piezoelectric layer, and the upper electrode layer along a stacking direction forms a resonant region. In this resonant region, the surface, which is away from the substrate, of at least one of the lower electrode layer, the piezoelectric layer, and the upper electrode layer is etched to form an etched region. The depth of the etched region is less than the thickness of an etched layer, and the area of the etched region is less than the area of the resonant region. By controlling the etching area ratio of the resonant region to the etched region, the resonator can obtain a plurality of different resonant frequencies on the same wafer without increasing processes.
