Product Description
4inch Sapphire Wafer DSP Diameter 100mm Thickness 500μm Ra ≤ 0.2nm For Micro-LED
The 4-inch sapphire wafer is a high-quality optical-grade substrate fabricated from single-crystal aluminum oxide (α-Al₂O₃) via Edge-defined Film-fed Growth (EFG) or Kyropoulos (KY) methods, with standard dimensions of 100mm±0.2mm diameter and customizable thickness (0.3-1.0mm). Compared to 6-inch wafers, the 4-inch sapphire wafer offers greater cost efficiency for R&D and small-batch production, particularly suited for applications requiring high crystalline quality but not large-area formats, such as UV LEDs, RF devices, and specialized sensors. Its balanced performance and affordability make it ideal for research institutions, startups, and small-to-medium chip manufacturers.
