What are the flatness parameters (TTV, BOW, WARP) for this 2-inch off-cut sapphire substrate?

The total thickness variation (TTV) is <10 µm, bow (BOW) is <15 µm, and warp (WARP) is <15 µm. These tight tolerances ensure uniform thickness and minimal warpage, critical for consistent device performance in wafer processing.

What is the surface finish on the front and back sides of this single-side polished substrate?

The front side is epi-ready with Ra <0.3 nm, suitable for direct epitaxial growth. The back side is fine ground with Ra <1.2 µm, which aids in handling and reduces sticking during processing.

How is the substrate packaged and are custom thickness options available?

The substrate is packaged as 1 piece per set. Custom thickness options are available in addition to the standard 430 ±25 µm thickness. For specific packaging or thickness preferences, contact the technical sales team at inquiry@atomfair.com.

This 2-inch off-cut sapphire substrate offers high-purity Al2O3 with epi-ready front-side polish and tight geometric tolerances, but the single-side polish and specific off-cut angle restrict its use to dedicated epitaxial workflows.

Positive

  • High-purity monocrystalline Al2O3: >99.99% purity via KY method minimizes contaminants for sensitive thin-film growth and optical applications.
  • Epi-ready front-side surface: Front-side roughness Ra <0.3 nm enables direct use for epitaxial deposition without additional polishing steps.

Trade-offs

  • Single-side polished only: Back-side is fine ground (Ra <1.2 um), limiting use in double-side optical transmission or symmetrical processing applications.
  • Specific off-cut orientation: A/C off-cut at 1 degree is tailored for specific epitaxial processes; may not be compatible with standard c-plane or other common orientations.
