ACOUSTIC WAVE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18220854 titled 'ACOUSTIC WAVE DEVICE
Simplified Explanation
The patent application describes an acoustic wave device that consists of several layers and electrodes.
- The device includes a crystal substrate, which serves as a base.
- A layer of silicon carbide is deposited on top of the crystal substrate.
- On top of the silicon carbide layer, there is a layer of lithium tantalate.
- Finally, an interdigital transducer electrode is placed on the lithium tantalate layer, which consists of multiple first and second electrode fingers.
The innovation in this patent application lies in the specific combination of materials and layers used in the acoustic wave device.
