The present invention warpage is small, with no cracks or scratches, deer, temperature characteristic is better than the conventional rotary Y cut lithium tantalate substrate, electro-mechanical coupling coefficient is large, and further, Q value of the device is high tantalum provision of lithium single crystal substrate.
A By the crystal orientation is Li is diffused into the interior from the rotation 36 ° Y~49 ° Y rotated Y-cut lithium tantalate substrate surface of a cut, the concentration profile of Li concentration of the substrate surface and the substrate internal different There are formed, from the substrate surface, up to 5-15 times the depth of the wavelength of the surface acoustic wave or leaky surface acoustic wave propagating substrate surface, single-polarized treated lithium tantalate single having a schematic uniform Li concentration crystal substrate.
