ACOUSTIC WAVE DEVICE AND METHOD FOR MANUFACTURING THE SAMEAn acoustic wave device includes: a piezoelectric substrate; a dielectric layer formed on the piezoelectric substrate; and first and second comb-tooth electrodes formed on the dielectric layer, the dielectric layer having a first thickness between the first comb-tooth electrodes and the piezoelectric substrate and a second thickness between the second comb-tooth electrodes and the piezoelectric substrate, the first and second thicknesses being different from each other.Figure 7 |
