| titleOfInvention | Bulk acoustic wave resonator with piezoelectric layer having insert structure, and filter and electronic device |
| abstract | The present invention relates to a bulk acoustic wave resonator, comprising: a substrate; an acoustic mirror; a bottom electrode; a top electrode; a piezoelectric layer; the region where the acoustic mirror, bottom electrode, piezoelectric layer, and top electrode overlap in the direction of the thickness of the substrate is the effective region of the resonator; the piezoelectric layer is provided with a composite insertion structure arranged along the edge of the effective region; the composite insertion structure comprises a first insertion layer and a second insertion layer; in the top-down view of the resonator at least a part of the first insertion layer overlaps the effective region, and in the top-down view of the resonator the first insertion layer and the second insertion layer at least partially overlap; the first insertion layer is a metal material and the second insertion layer is air or a dielectric material, or the first insertion layer is a dielectric material and the second insertion layer is air. The invention also relates to a filter and an electronic device. |
