Sapphire Wafer 12inch AL2O3 Customization DSP SSP C plane A plane M plane LED Sapphire substrate

Product Description of 12inch Sapphire wafer:

Sapphire is a material of a unique combination of physical, chemical, and optical properties, which make it resistant to high temperature, thermal shock, water and sand erosion, and scratching. It is a superior window material for many IR applications from 3µm to 5µm. C-plane sapphire substrates are widely used to grow III-V and II-VI compounds such as GaN for blue LED and laser diodes, while R-plane sapphire substrates are used for the hetero-epitaxial deposition of silicon for microelectronic IC applications.

The character of 12inch Sapphire wafer:

Sapphire wafers are a commonly used semiconductor material, usually referring to alumina (Al2O3) crystals. Here are some of the characteristics of sapphire wafers:
1. Optical properties:
Sapphire wafers have excellent optical transparency, especially in the visible and near-infrared spectral range. This makes sapphire wafers widely used in optical sensors, lasers, and optoelectronic devices.
2. Hardness and wear resistance:
Sapphire wafers have a very high hardness, second only to diamond, and therefore have good wear resistance. This property makes sapphire wafers very useful in applications that require scratch-resistant and wear-resistant surfaces, such as watch surface coatings and optical Windows.
3. Chemical stability:
Sapphire wafers have good chemical stability and can resist acid and alkali corrosion. This makes it advantageous for use in chemical sensors, biomedical devices, and high temperature/high pressure environments.
4. Thermal properties:
Sapphire wafers have high thermal conductivity and thermal capacity, which makes them more stable in high temperature environments. Therefore, sapphire wafers are an ideal material choice in high-temperature sensors, laser cooling systems, and high-temperature electronic devices.

Applications of  12inch Sapphire wafer:

1. C-plane sapphire wafers are extensively used for the growth of wide-bandgap III-V and II-VI semiconductor materials, such as gallium nitride (GaN), aluminum nitride (AlN), indium nitride (InN), zinc oxide (ZnO for UV light emission), and tin oxide (SnO2 for UV light emitting materials).
 
2. Moreover, standard C-plane (0001) sapphire wafers find wide applications in the preparation of LED white, blue, UV, and deep UV epitaxial wafers through techniques like metalorganic chemical vapor deposition (MOCVD), molecular beam epitaxy (MBE), plasma-enhanced chemical vapor deposition (PECVD), and other epitaxial growth methods.
 
3. Standard sapphire wafers can also serve as substrates for heterojunction bipolar transistors (HBTs), laser diodes (LDs), UV detectors, nanotubes, and as heat dissipation materials for high-temperature, high-power, and high-frequency electronic devices.

FAQ:

1. Q: What is the difference between sapphire and silicon wafers?
    A: LEDs are the most popular applications for sapphire. The material is transparent and is an excellent conductor of light. In comparison, silicon is opaque and does not allow for efficient light extraction. The semiconductor material is ideal for LEDs, however, because it is both cheap and transparent.
2. Q:What is sapphire in semiconductor?
    A: High purity single crystal (AI2O3), Sapphire is ideal for the precise and demanding requirements of semiconductor manufacturing, offering a transparent yet durable, particle-free, cost-effective solution in aggressive environments that prove too challenging for lower technology materials.
3 .Q: Why is there silicon on Sapphire?
    A: SOS is part of the silicon-on-insulator (SOI) family of CMOS (complementary MOS) technologies. ) on heated sapphire substrates. The advantage of sapphire is that it is an excellent electrical insulator, preventing stray currents caused by radiation from spreading to nearby circuit elements.
