ABSTRACT:
In a method of manufacturing a surface-acoustic-wave device composed of, at least, a substrate through which a surface acoustic wave is propagated, the propagation velocity of the surface acoustic wave is adjusted by applying light directly to the surface of the substrate constituting the device or through a thin film of asymmetric lattice configuration deposited thereon by sputtering, the thin film having a thickness not exceeding a value of 0.03 times as large as the wavelength of the surface acoustic wave propagated through the substrate.
