Multifunctional 2 Inch Glass Carrier Wafer , Sapphire Substrate Single Side Flat

2 Inch Single Side Polished Sapphire Wafer Sapphire Substrate With Flat

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.

The C-Plane sapphire substrate is used to grow III-V and II-VI group deposited films, such as gallium nitride, which can produce blue LED products, laser diodes, and infrared detector applications. This is mainly because the process of sapphire crystal growth along the C axis is mature, the cost is relatively low, and the physical and chemical properties are stable. The technology for epitaxial growth on the C surface is mature and stable. The C axis has crystal gloss, and the other axes have negative gloss; the C plane is flat and it is best to cut.
