6-Inch Sapphire Wafers: Prices, Providers, and Future Outlook
Sapphire wafers, especially the 6-inch sapphire wafer, have become a cornerstone of modern technology. With exceptional hardness, thermal stability, and optical clarity, these wafers are critical to industries ranging from LED lighting to aerospace. This article delves into the detailed parameters, market trends, and key suppliers of 6-inch sapphire wafers, while highlighting the advantages of manufacturer direct procurement. Whether you’re an engineer or a procurement manager, understanding the price dynamics and supplier landscape will help you make informed decisions.
1. Technical Parameters of 6-Inch Sapphire Wafers
A 6-inch sapphire wafer (150 mm diameter) is fabricated from high-purity aluminum oxide (Al₂O₃) crystals. Key parameters include:
- Thickness Options: 350 μm for micro-LEDs and 0.5 mm for power devices. The 350 μm wafer reduces thermal resistance by 15%, while the 0.5 mm version enhances mechanical strength threefold .
- Surface Polish: Single-side polishing (SSP) achieves a surface roughness of <0.5 nm, while double-side polishing (DSP) reaches <0.3 nm, ideal for high-end optics .
- Crystal Orientation: C-plane (0001) is standard for GaN epitaxial growth, with lattice mismatch as low as 16% .
- Thermal Properties: Melting point of 2053°C and thermal conductivity of 35 W/mK, suitable for high-temperature applications .
These parameters make the 6-inch sapphire wafer a preferred substrate for semiconductors, ensuring durability and performance under extreme conditions.
2. Market Price Analysis of 6-Inch Sapphire Wafers
The price of a 6-inch sapphire wafer varies based on thickness, polish type, and quantity. Current market data shows:
- DSP Wafers: Priced at 50 per wafer for bulk orders (25+ pieces) .
- Standard Wafer: A 1.0 mm-thick, 6-inch wafer costs around $50 (wholesale) .
- Customization: Factors like PSS (patterned sapphire substrate) or epitaxial readiness can increase costs by 20–30% .
The growing demand for LED and 5G technologies is expected to stabilize prices, with bulk manufacturer direct purchases offering the best value.
