200mm LiNbO3 Wafer Substrate For Optical Waveguides And Microwaveguides

Product Description:

8-inch LiNbO3 wafers refer to the specific size of LiNbO3 crystal substrates commonly used in the fabrication of optoelectronic devices and integrated circuits. These wafers are made from high-purity lithium niobate crystals and offer several advantages due to their larger size. Here is a description of 8-inch LiNbO3 wafers:

1. Size: 8-inch LiNbO3 wafers have a diameter of approximately 200 millimeters (8 inches), making them larger than smaller-sized wafers like 4-inch or 6-inch wafers. The larger surface area of 8-inch wafers allows for higher device density and increased production efficiency.
2. Thickness: The standard thickness of 8-inch LiNbO3 wafers ranges from 0.5 to 1 millimeter. However, custom thicknesses can also be obtained based on specific application requirements.
3. Crystal Orientation: 8-inch LiNbO3 wafers can be cut and oriented along different crystal planes, typically the Y- and X-cut orientations, which are commonly used in many optoelectronic devices. However, other crystal orientations may also be available depending on the specific application needs.
4. Advantages: The larger size of 8-inch LiNbO3 wafers offers several advantages:

Increased Device Capacity: The larger surface area allows for a higher number of devices and integrated circuits to be fabricated on a single wafer, thereby improving production capacity and yield.

Enhanced Integration: With a larger area, 8-inch wafers enable higher device integration and improved performance due to the availability of more real estate for components and interconnects.

Improved Uniformity: The manufacturing process for larger wafers often results in better consistency and uniformity across the wafer, contributing to improved device performance and yield.

1. Availability: 8-inch LiNbO3 wafers are commercially available from various specialized semiconductor material manufacturers. These suppliers provide ready-made 8-inch wafers or offer customization options to meet specific application requirements.

Applications:

8-inch LiNbO3 wafers find applications in various fields where their unique optical and electro-optic properties are utilized. For example: Optical Modulators, Frequency Conversion, Acousto-Optic Devices, Integrated Optics, Nonlinear Optical Devices, Optical Sensors.

Packing and Shipping:

LiNbO3 Wafers should be packaged and shipped in accordance with the following guidelines:

• LiNbO3 Wafers should be packaged in an antistatic bag.
• The package should be padded with cushioning material to protect against shock.
• The package should be clearly labeled with the product name and the contents of the package.
• The package should be sent by a reputable courier service.
• The package should be tracked and insured.
