Latest Patents

Among his latest patents is the innovative surface acoustic wave device and its fabrication process. This invention features a piezoelectric substrate made from either 64° rotated Y-cut lithium niobate (64LN) or 36° rotated Y-cut lithium tantalate (36LT). The design includes an interdigital electrode constructed from a titanium buffer metal film and an aluminum film. On the 64LN substrate, both films are converted into a single-crystal film, which can be identified through selected-area electron diffraction. In the case of the 36LT substrate, the aluminum film, placed with a titanium buffer in between, is engineered to produce a high-orientation, polycrystalline aluminum film oriented in the (111) direction. This innovation significantly restricts the migration of aluminum atoms, ultimately improving the power durability of the device.
