Product Description

8inch Al2O3 Sapphire Optical Windows DSP thichness 0.5mm Orientation C-Axis

Product description

Sapphire wafers play a critical role in the semiconductor and optoelectronics industries, offering unique material properties that make them ideal for a wide range of applications. Unlike traditional semiconductor wafers made primarily of silicon, sapphire wafers are fabricated from a crystalline form of aluminum oxide (Al2O3) called corundum. This material is exceptionally hard, ranking second only to diamonds, and exhibits excellent optical transparency across a broad spectrum, ranging from ultraviolet to infrared wavelengths.

The manufacturing process of sapphire wafers involves the growth of a single crystal of corundum using techniques such as the Kyropoulos or Edge-defined Film-fed Growth (EFG) method. Once the crystal is grown, it is precisely sliced into thin, flat wafers using advanced cutting techniques. Sapphire wafers demonstrate remarkable mechanical strength, high thermal conductivity, and resistance to chemical corrosion, making them highly suitable for demanding applications.

Product characteristics

In addition to their exceptional material properties, sapphire wafers have several other advantageous characteristics that contribute to their widespread use in various industries. Here are some further details:

Wide Bandgap: Sapphire possesses a wide bandgap, which makes it an excellent choice for applications requiring high-temperature operations and resistance to electrical breakdown. Its wide bandgap allows for efficient power handling and reduces leakage currents, enhancing the performance and reliability of semiconductor devices.

Optical Applications: The excellent optical transparency of sapphire makes it highly desirable for optical components and systems. It enables the transmission of light across a broad range of wavelengths, making sapphire wafers suitable for applications such as LEDs, laser diodes, optical windows, lenses, and substrates for thin-film deposition.

High Mechanical Strength: Sapphire wafers exhibit remarkable mechanical strength, making them resistant to cracking, chipping, and physical damage. Their robustness allows for easier handling during the manufacturing process and ensures the durability and longevity of devices and components.

Chemical Resistance: Sapphire is highly resistant to chemical corrosion and can withstand exposure to various harsh chemicals, acids, and alkalis. This quality is particularly valuable in applications where the wafer needs to endure corrosive environments or come into contact with aggressive substances.

Thermal Conductivity: Sapphire has excellent thermal conductivity, enabling efficient dissipation of heat generated within devices. This property is crucial for high-power applications, as it helps maintain optimal operating temperatures, enhances device performance, and prolongs the lifespan of components.

Due to these outstanding characteristics, sapphire wafers find applications in diverse fields, including semiconductor manufacturing, optoelectronics, aerospace, defense, telecommunications, and more. Their versatility and reliability make them a preferred choice for demanding applications that require exceptional performance and durability.
