  • Patent number: 10230349
    Abstract: An acoustic wave device is an end surface reflection-type acoustic wave device and includes a substantially rectangular-parallelepiped composite substrate in which a piezoelectric substrate and a supporting substrate are joined together, with a pair of IDT electrodes provided on the substrate in such a manner as to be intercalated with each other. A chipping size in a first side face of the substrate is 1/10 of a wavelength ? of an acoustic wave or smaller, the face extending orthogonally to a direction of acoustic-wave propagation. A chipping size in a second side face of the substrate is larger than the chipping size in the face and is, for example, ½ of the wavelength ? or larger and 50 times the wavelength ? or smaller, the face extending in the direction of acoustic-wave propagation.

  • Patent number: 10211389
    Abstract: In the composite substrate 10, the piezoelectric substrate 12 and the support substrate 14 are bonded by direct bonding using an ion beam. One surface of the piezoelectric substrate 12 is a negatively-polarized surface 12a and another surface of the piezoelectric substrate 12 is a positively-polarized surface 12b. An etching rate at which the negatively-polarized surface 12a is etched with a strong acid may be higher than an etching rate at which the positively-polarized surface 12b is etched with the strong acid. The positively-polarized surface 12b of the piezoelectric substrate 12 is directly bonded to the support substrate 14. The negatively-polarized surface 12a of the piezoelectric substrate 12 may be etched with the strong acid.
