AMO Scientific 2 Inch C-Plane Sapphire Wafer (0001) – Single Crystal Al₂O₃, SSP/DSP
AMO Scientific 2 Inch C-Plane Sapphire Wafer (0001) – Single Crystal Al₂O₃, SSP/DSP
AMO Scientific 2 Inch C-Plane Sapphire Wafers are high-purity single-crystal Al₂O₃ substrates with a nominal diameter of 50.8 mm and C-plane (0001) crystal orientation. Available in both single-side polished (SSP) and double-side polished (DSP) configurations, these sapphire wafers are suitable for semiconductor research, thin-film deposition, optical applications, material research, and other laboratory processes.
Standard options include 430 ± 25 µm SSP and 400 ± 25 µm DSP wafers. The C-plane sapphire substrate combines high mechanical hardness, chemical stability, electrical insulation, optical transparency, and thermal stability. Custom thicknesses and specifications are available upon request.
