Multifunctional 150mm Dia LED Sapphire Ingot Optical High Mechanical Strength

Double Side Polished 6 Inch Optical LED Sapphire Wafer Sapphire Ingot

 

Sapphire (Sapphire, also known as white sapphire, molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. Widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.). At the same time, it is also a widely used single crystal substrate material, and it is the first choice for the blue, violet, and white light emitting diode (LED) and blue laser (LD) industries (the sapphire substrate needs to be epitaxial gallium nitride film first) , Is also an important superconducting film substrate.

 

Generally, the epitaxial layers of GaN-based materials and devices are mainly grown on sapphire substrates. Sapphire substrate has many advantages: firstly, the production technology of sapphire substrate is mature and the device quality is good; secondly, sapphire is very stable and can be used in the high-temperature growth process; finally, sapphire has high mechanical strength and is easy to handle And cleaning. Therefore, most processes generally use sapphire as the substrate.

 

Sapphire crystal has excellent optical properties, mechanical properties and chemical stability, high strength, high hardness, erosion resistance, and can work under severe conditions close to 2000 ℃, so it is widely used in infrared military devices, satellite space technology, Window material for high-intensity laser. Its unique lattice structure, excellent mechanical properties, and good thermal properties make sapphire crystals the most ideal semiconductors for practical applications such as GaN/Al2O3 light-emitting diodes (LED), large-scale integrated circuits SOI and SOS, and superconducting nanostructured films. Substrate material. In recent years, with the development of modern science and technology, new requirements have been continuously put forward for the size and quality of sapphire crystal materials.

 

The production process of synthetic sapphire: preparing raw materials → filling raw materials and setting up seeds → vacuuming the furnace body → heating the furnace body (adding molybdenum heat shield and tungsten heat shield to the furnace body) → raw material melting → welding seed crystals → crystal neck growth →Crystal growth→Separation of the crystal from the crucible→Cooling→Remove the crystal.
