ACOUSTIC WAVE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18537870 titled 'ACOUSTIC WAVE DEVICE
Simplified Explanation
The patent application describes an acoustic wave device with a piezoelectric layer having an anisotropic coefficient of linear expansion, first and second electrodes, and a cavity in the support.
- The device includes a support, a piezoelectric layer with an anisotropic coefficient of linear expansion, first and second electrodes, and a cavity in the support.
- The first and second electrodes overlap the cavity in plan view, and the through-hole is line symmetric about an axis passing through the center of the cavity.
- The through-hole extends in the direction of greatest coefficient of linear expansion of the piezoelectric layer.

Original Abstract Submitted
An acoustic wave device includes a support, a piezoelectric layer with an anisotropic coefficient of linear expansion, and including first and second main surfaces, at least one through-hole, a first electrode in or on the first main surface, and a second electrode in or on the second main surface and opposed to the first electrode. A cavity is provided in the support. At least a portion of the first and second electrodes overlaps the cavity in plan view. In plan view, the at least one through-hole is line symmetric about an axis of symmetry that passes a center of the cavity in a region where the first and second electrodes overlap each other and that extends in a direction in which the coefficient of linear expansion of the piezoelectric layer is greatest.
