Abstract: A method of manufacture for an acoustic resonator device. The method includes forming a nucleation layer characterized by nucleation growth parameters overlying a substrate and forming a strained piezoelectric layer overlying the nucleation layer. The strained piezoelectric layer is characterized by a strain condition and piezoelectric layer parameters. The process of forming the strained piezoelectric layer can include an epitaxial growth process configured by nucleation growth parameters and piezoelectric layer parameters to modulate the strain condition in the strained piezoelectric layer. By modulating the strain condition, the piezoelectric properties of the resulting piezoelectric layer can be adjusted and improved for specific applications.

Abstract: A method of manufacture for an acoustic resonator or filter device. In an example, the present method can include forming metal electrodes with different geometric areas and profile shapes coupled to a piezoelectric layer overlying a substrate. These metal electrodes can also be formed within cavities of the piezoelectric layer or the substrate with varying geometric areas. Combined with specific dimensional ratios and ion implantations, such techniques can increase device performance metrics. In an example, the present method can include forming various types of perimeter structures surrounding the metal electrodes, which can be on top or bottom of the piezoelectric layer. These perimeter structures can use various combinations of modifications to shape, material, and continuity. These perimeter structures can also be combined with sandbar structures, piezoelectric layer cavities, the geometric variations previously discussed to improve device performance metrics.
