The Detail for 2inch c-axis wafers
Sapphire is a single alumina crystal and the second-hardest material in nature, after diamond. Sapphire has good light transmittance, high strength, collision resistance, wear resistance, corrosion resistance, and high temperature and high-pressure resistance, biocompatibility is an ideal substrate material for the production of semiconductor optoelectronic devices, the electrical properties of sapphire make it become the substrate material for the production of white and blue LED.
Our company's long-term production thickness ≧0.1mm, and its shape size ≧Φ2" high precision sapphire wafer. In addition to the conventional Φ2 ", Φ4 ", Φ6 ", Φ8 ", Φ10 ", Φ12 ", other sizes can be customized, please contact our sales staff.

The Applications for sapphire wafer substrates
Sapphire is composed of alumina (A1203), which is composed of three oxygen atoms and two aluminum atoms in a covalent bond type, and its crystal structure is a hexagonal lattice structure. It is often used on A-Plane, C-Plane, and R-Plane facets. Due to its wide optical penetration band, sapphire has excellent light transmission from near ultraviolet (190nm) to mid-infrared. Therefore, it is widely used in optical components, infrared devices, high-intensity laser lens materials, and mask materials, it has the characteristics of high sound speed, high-temperature resistance, corrosion resistance, high hardness, high light transmittance, high melting point (2045°C) and so on. It is a rather difficult material to process, so it is often used as a photoelectric element material. At present, the quality of ultra-high brightness white/blue LED depends on the material quality of nitride epitaxial (Ga), while the quality of nitride epitaxial is closely related to the surface processing quality of the sapphire substrate used. The lattice constant mismatch rate between the C surface of sapphire (single crystal A1203) and the films of II-V and II-VI groups are small. At the same time, it meets the requirement of high-temperature resistance in the GaN epitaxial process, making the sapphire wafer the key material for making white/blue/green LEDs.
