Patent number: 9564574Abstract: In a method for manufacturing a piezoelectric device, a silicon oxide film is deposited by sputtering on a surface of a single-crystal piezoelectric substrate closer to an ion-implanted region, and a silicon nitride film is deposited by sputtering on a surface of the dielectric film opposite to a side thereof closer to the single-crystal piezoelectric substrate.
