Sapphire Wafer
Our high quality sapphire wafers are available in standard diameters from 2” to 150mm. The can be single or double side polished in C, A, and R plane orientations.
What is a Sapphire Wafer?
A Sapphire Wafer is a thin slice of synthetic sapphire (Al₂O₃), typically grown using the Kyropoulos (Kr) technique. It serves as a substrate material and foundational layer, upon which other semiconductor materials are deposited or grown.
Sapphire (Al₂O₃) is a hexagonal crystal, and its orientation significantly influences the wafer’s optical, mechanical, thermal, and electrical properties. The orientation is defined by the alignment of the wafer surface relative to the crystal axes, commonly expressed as C-plane (0001), R-plane (11-02), and A-plane (11-20).

Why are Sapphire Wafers used to manufacture Semiconductor Devices?
Sapphire wafers offer numerous benefits, making them the preferred choice for semiconductor fabrication:
- Durability and Chemical Resistance: Sapphire withstands extreme temperatures (up to 2000°C) and aggressive chemicals used in semiconductor manufacturing, outperforming materials like quartz in longevity and reliability.
- Excellent Lattice Match: Sapphire wafers offer a good lattice match with materials such as Gallium Nitride (GaN), Aluminium Nitride (AlN), and Silicon (Si), helping to minimise strain and reduce crystal defects during epitaxial growth.
- High Thermal Conductivity: Its ability to dissipate heat efficiently makes it ideal for high-power and high-frequency devices, especially those operating in harsh environments.
- Electrical Insulation: Sapphire is an excellent electrical insulator, which helps reduce parasitic capacitance and leakage currents in integrated circuits.
- Optical Transparency: This property makes sapphire suitable for optical components, including windows and substrates in optoelectronic devices.

Applications for Sapphire Wafers
Key Applications
Sapphire wafers are used extensively for HB-LED production due to the good lattice match between III-V and II-VI materials and Sapphire. It also has high resistance to thermal shock and can produce low stress layers.
Sapphire is also a good substrate for Si EPI growth due to very low defectivity and low loss properties. It is also widely used in the fabrication of high voltage power and frequency devices where the thermal conductance, very stable dielectric constant, and low loss properties enable it to operate reliably in very harsh conditions. It also has high optical transmission across a wide range of wavelengths.
