Abstract
An acoustic wave device configured to generate a surface acoustic wave having a wavelength L is disclosed. The acoustic wave device can include a substrate, a piezoelectric layer that includes lithium niobate, an interdigital transducer electrode, an overcoat dielectric layer, and/or a raised frame structure. The piezoelectric layer is disposed at least partially between the substrate and the interdigital transducer electrode. The overcoat dielectric layer is positioned over the interdigital transducer electrode. The raised frame structure is positioned over the overcoat dielectric layer. The raised frame structure includes a material of the overcoat dielectric layer. The raised frame structure is positioned in an edge region within 0.25 L and 0.45 L from an edge of an active region where the surface acoustic wave is generated. The acoustic wave device can include a trap-rich layer over the substrate and an intervening dielectric layer over the trap-rich layer.
