What is the typical thickness and tolerance for the 2-inch M-Plane sapphire substrate?
The standard thickness is 430 +/- 25 um, with optional thicknesses of 200 um, 400 um, and 1000 um available for specific application requirements.
What are the flatness specifications (TTV, BOW, WARP) for this sapphire substrate?
The total thickness variation (TTV), bow (BOW), and warp (WARP) are all less than 10 um, ensuring high flatness critical for epitaxial growth and thin-film processing.
What is the surface roughness on the front and back sides of the double-side polished substrate?
Both the front and back sides are epi-ready with Ra <0.3 nm, providing a smooth surface suitable for high-quality thin film deposition and device fabrication.
This 2-inch M-Plane sapphire substrate offers high-purity (>99.99%) monocrystalline Al2O3 with double-side polished epi-ready surfaces (Ra<0.3 nm) and tight geometry tolerances (TTV, BOW, WARP <10 um), making it suitable for demanding epitaxial growth and thin-film applications. The standard thickness of 430±25 um provides a balance of mechanical stability and process compatibility.
Positive
- High-purity monocrystalline Al2O3: Material purity >99.99% minimizes defect density for high-quality epitaxial growth.
- Double-side polished epi-ready surfaces: Both front and back sides exhibit Ra<0.3 nm roughness, enabling low-scattering interfaces for thin-film deposition.
Trade-offs
- Tight geometry tolerances require careful handling: TTV, BOW, and WARP all specified at <10 um, necessitating precise substrate mounting and thermal management during processing to maintain flatness.
- Single-piece packaging for batch scaling: Supplied as 1 piece per set, requiring multiple orders for multi-substrate processes.
