What are the thickness and flatness specifications for this 2-inch off-cut sapphire substrate?
The substrate has a thickness of 430 +/- 25 um, with TTV <10 um, BOW <15 um, and WARP <15 um, ensuring high planarity for epitaxial deposition.
What surface roughness specifications are provided on the front and back sides of this single-side polished sapphire substrate?
The front side is epi-ready with Ra <0.3 nm, and the back side is fine ground with Ra <1.2 um, making it suitable for immediate use in thin-film growth applications.
What is the standard packaging and ordering process for this off-cut sapphire substrate?
The substrate is packaged as 1 piece per set, with package size following the selected configuration. Custom thickness and packaging preferences can be accommodated by contacting the technical sales team.
The 2-inch off-cut sapphire substrate with A/C 5-degree orientation offers epi-ready front-side roughness (<0.3 nm) and tight geometric tolerances (TTV <10 μm, BOW <15 μm, WARP <15 μm), suitable for thin-film epitaxy and device fabrication. The single-side polished finish and fine-ground back side require careful handling for thermal management applications.
Positive
- Epi-ready front-side roughness: Front-side surface roughness Ra <0.3 nm enables direct epitaxial growth without additional polishing steps, reducing processing time and contamination risk.
- Tight geometric tolerances: TTV <10 μm, BOW <15 μm, and WARP <15 μm ensure uniform thin-film deposition and consistent device performance across the substrate.
Trade-offs
- Single-side polished only: Back-side is fine ground with Ra <1.2 μm, which may limit thermal contact efficiency or require additional processing for double-side polished applications.
- Fixed off-cut angle: The 5-degree off-cut angle is specific to this SKU and may not be optimal for all epitaxial growth conditions, particularly for lattice-mismatched heterostructures.
