What are the flatness and thickness specifications for the 2-inch off-cut sapphire substrate?
The substrate has a thickness of 430 +/-25 µm, with TTV less than 10 µm, BOW less than 15 µm, and WARP less than 15 µm as specified in the technical specifications. These parameters ensure high planarity critical for uniform thin film deposition.
What is the surface roughness on the front and back sides of the single-side polished substrate?
The front-side roughness is epi-ready with Ra less than 0.3 nm, suitable for epitaxial growth. The back-side roughness is fine ground with Ra less than 1.2 µm, providing a matte texture for handling and mounting.
Can I order a custom thickness for this off-cut sapphire substrate?
Yes, the standard thickness is 430 +/-25 µm, but the product description states that any preferred custom thickness is available. Contact the technical sales team via inquiry@atomfair.com for custom thickness options.
This 2-inch off-cut sapphire substrate provides a high-purity monocrystalline Al2O3 surface with epi-ready front-side polish (Ra <0.3 nm) and tight geometric tolerances (TTV <10 μm, BOW <15 μm, WARP <15 μm), suitable for thin-film epitaxy and research applications requiring a specific C/A off-cut of 10 degrees.
Positive
- High-purity monocrystalline Al2O3: Material purity >99.99% (KY) ensures minimal contamination for sensitive epitaxial growth and device fabrication.
- Epi-ready front-side polish and tight tolerances: Front-side roughness Ra <0.3 nm, TTV <10 μm, BOW <15 μm, and WARP <15 μm provide a consistent, low-defect substrate for high-quality thin-film deposition.
Trade-offs
- Single-side polished only: Back-side is fine ground with Ra <1.2 μm, limiting applications that require double-side polished surfaces for optical or thermal contact.
- Fixed off-cut orientation and angle: This SKU specifies a 10° C/A off-cut; experiments requiring other off-cut geometries or angles must source a different product variant.
