摘要： A method for manufacturing a boundary acoustic wave device prevents formation of discontinuous portions in a dielectric film without a significant decrease in the thickness of an IDT when the dielectric film is formed by deposition and without deterioration of electrical characteristics. The method includes the steps of forming an IDT on a piezoelectric substrate, forming a lower dielectric film so as to cover the IDT, conducting a planarizing step so as to smooth the rough surface of the lower dielectric film, and forming an upper dielectric film so as to cover the lower dielectric film of which the rough surface is smoothed.

摘要： A method of forming an electrode pattern of a surface acoustic wave device easily and reliably prevents the occurrence of an abnormality in the shape of a resist pattern. In the electrode pattern forming method, a resist layer is formed on a top surface of a piezoelectric substrate, and then exposed to ultraviolet rays through a photomask provided above the top surface of the piezoelectric substrate to form a resist pattern on the surface of the piezoelectric substrate. Furthermore, a conductor film is formed on the top surface of the piezoelectric substrate, and the resist pattern is removed by a liftoff method to form an electrode pattern of the surface acoustic wave device. Exposure is performed using ultraviolet rays having a wavelength which is completely absorbed into the piezoelectric substrate without reaching the bottom surface of the piezoelectric substrate.
