Short Description:
Sapphire (Sapphire, also known as white gemstone, 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 industry, national defence and scientific research in many fields (such as high temperature infrared window, etc.). At the same time it is also a wide range of single crystal substrate materials, is the current blue, violet, white light-emitting diodes (LED) and blue laser (LD) industry’s first choice of substrate (need to be the first in the sapphire substrate epitaxial Gallium Nitride film), but also an important superconducting thin film substrate!
Product Specification
8-inch sapphire wafers have a variety of applications due to their properties of high hardness, chemical resistance, and excellent thermal conductivity. Some common applications of 8-inch sapphire wafers include:
Semiconductor Industry: Sapphire wafers are used as substrates for fabricating high-performance electronic devices such as light-emitting diodes (LEDs), radio frequency integrated circuits (RFICs), and high-power electronic devices.
Optoelectronics: Sapphire wafers are used in the manufacture of optoelectronic devices such as laser diodes, optical windows, lenses, and substrates for epitaxial growth of gallium nitride (GaN) films for blue and white LEDs.
Aerospace and Defense: Due to its high strength and resistance to harsh environments, sapphire wafers find applications in aerospace and defense industries for making sensor windows, transparent armor, and missile domes.
Medical Devices: Sapphire wafers are used in the manufacturing of medical devices such as endoscopes, surgical tools, and implants. Sapphire’s biocompatibility and resistance to chemicals make it suitable for such applications.
Watch Industry: Sapphire wafers are used as the crystal cover on luxury watches due to their scratch resistance and clarity.
Thin-Film Applications: Sapphire wafers serve as substrates for growing thin films of various materials, including semiconductors and dielectrics, used in research and development, as well as in industrial production processes.
These are just a few examples of the wide-ranging applications of 8-inch sapphire wafers. The use of sapphire in various industries is continually expanding as its unique properties are further explored and optimized.
