Compared with traditional glass and other optical substrate materials, silicon carbide (SiC) wafers offer superior optical and thermal properties, making them an ideal platform for high-performance AR optical components.

With a high refractive index of approximately 2.7, SiC enables compact optical designs with improved light coupling efficiency, wider field of view, and enhanced image quality for augmented reality applications.

Our 8 inch SiC wafers feature excellent crystal quality, high purity, superior thermal conductivity, and customizable specifications to meet different optical and semiconductor manufacturing requirements.

Why Choose SiC Wafer for AR Glasses and Optical Waveguides?

The development of next-generation AR glasses requires optical materials with high refractive index, excellent thermal management capability, and reliable manufacturing performance.

Silicon carbide wafers provide several key advantages compared with conventional optical substrates.

1. High Refractive Index for Improved AR Optical Performance

One of the major advantages of SiC substrate materials is their high refractive index.

The refractive index of silicon carbide is significantly higher than traditional glass materials, allowing AR waveguide designers to achieve:

• Larger field of view

• Improved optical efficiency

• More compact optical modules

• Better light transmission performance

For advanced AR glasses and augmented reality waveguide applications, high-index HPSI SiC wafers provide an effective solution for improving optical system performance.

2. Excellent Thermal Conductivity and Device Reliability

AR optical systems often integrate compact optical engines and electronic components that generate heat during operation.

Silicon carbide wafers have excellent thermal conductivity, helping efficiently dissipate heat and improve the stability and reliability of optical devices.

The superior thermal characteristics of SiC substrates make them suitable for demanding applications requiring long-term performance and consistent optical quality.

3. Large Diameter 8 Inch Wafer Platform for High Volume Manufacturing

The transition from small diameter substrates to 8 inch (200mm) SiC wafers enables higher production efficiency and improved manufacturing economics.

Compared with smaller wafer sizes, 200mm SiC wafers provide:

• Higher device output per wafer

• Better production efficiency

• Reduced manufacturing cost

• Compatibility with advanced semiconductor processes

HMT's 8 inch HPSI SiC wafers are designed to support future high-volume production requirements for AR optical components and semiconductor devices.
