Product Description
4-Inch C-Plane SSP Sapphire Wafer for GaN / III-Nitride Epitaxy
Overview
We produce 5N (99.999%) Purity monocrystalline Al₂O₃ for advanced semiconductor, optoelectronic, and optical applications.
These substrates are polished on a single side for excellent surface smoothness (Ra ≤ 0.2 nm). These substrates offer exceptional thermal stability (>1500 °C), high optical transmittance (~86–89% at 550 nm), and tight thickness uniformity (TTV ≤20 µm). They are ideal for LED epitaxial growth, GaN and III-nitride semiconductor devices, and high-temperature or optical applications.
Key Features
High-purity [5N (99.999%) Purity] single-crystal sapphire (Al₂O₃)
C-plane orientation (0001) with tight ±0.3° tolerance
Single side polished (SSP) surface, front Ra < 0.2 nm
Excellent flatness and low bow (<15 µm)
High thermal and chemical stability for harsh environments
Customizable axis, diameter, and thickness available

Why Choose C-Plane Sapphire?
Sapphire substrate is ideal for high-performance optical and electronic applications. Sapphire offers exceptional hardness (Mohs 9), high thermal stability up to ~1500 °C, and excellent chemical resistance, a perfect choice for demanding environments such as during the MOCVD and MBE crystalline growth procedures. Its c-plane strucgture is also reasonably compatible with the crystal structure of III-nitrides, facilitating epitaxial alignment and uniform crystal growth.
Packaging & Shipping
25 wafers in one cassette box by vacuum bag or customized method upon request
FAQ
Q: What is the optical transmittance range?
A: Transparent from ~200 nm (UV) to ~5000 nm (mid-IR).
Q: Is the wafer conductive?
A: No — sapphire is an insulator, ideal for preventing leakage currents in electronics.
Q: Can the wafer be customized?
A: Yes, we accept custom diameters, thicknesses, and axis orientation according to client specifications.
