Bonded Wafer for SAW Filter Application
NGK Bonded Wafer
  • By bonding silicon that has low thermal expansion and high quality single crystal piezoelectric substrate, we make it possible to improve thermal behavior without affecting its function.
  • With NGK's polishing technology, thickness of piezoelectric layer can be adjusted with high precision.
  • Size is available up to 6 inch.


  • By bonding Silicon and Piezoelectric Material, piezoelectric material is able to function without effect from heat.
  • NGK earns high credibility with its original bonding technology.
