8inch LiNbO3 Wafer


Lithium Tantalate Wafers 200mm


LiTaO3 Thin Wafers

Product Description

8inch 200mm 20-60um Lithium Tantalate LT LN Thin Wafers


LT & LN Wafer


The basic principle of SAW devices is the generation of elastic surface waves from electrical signals and their reconversion. The substrate material is a piezoelectric crystal such quartz (SiO2), lithium tantalate (LiTaO3) or lithium niobate (LiNbO3). This are single crystal materials, which are cut out after the growth process with a defined orientation to a wafer. NQW produced this wafer for SAW manufacture and R&D centres. Please find below typical specification requirements.



LT /LN Material

  • LT Lithium Tantalate (LiTaO3), LN Lithium Niobate (LiNbO3)
