AI AR 4H-SiC 6'' SiC Optics Wafer

HMT provides a 6 inch (150mm) optics-grade wafer based on a single-crystal 4H-SiC Wafer, tailored for high-performance applications in artificial intelligence (AI) and augmented reality (AR). This wafer leverages the superior material properties of Silicon Carbide—such as high thermal conductivity, rigidity, and low thermal expansion—to serve as an ideal platform for critical optical components in AR devices, AI-enabled sensors, and other advanced photonic systems requiring stability and durability. We also have 8 inch (200mm) optics sic wafers. Contact us and get preferential price.

Key Features and Advantages:

• Superior Material: 4H-SiC Crystal: The 4H polytype of Silicon Carbide is chosen for its exceptional properties, which are critical for high-performance optics. It offers an outstanding combination of high thermal conductivity, extreme hardness, low density, and remarkable chemical inertness. Most importantly for optical systems, it maintains excellent dimensional stability under severe thermal and mechanical stress.
  
  

• Large Format: 6-Inch Diameter: The 6-inch SiC wafer format enables the high-volume manufacturing of larger and more complex optical components. This significantly reduces the cost per die and allows for the production of monolithic optics for advanced systems, making it commercially viable for widespread adoption.
  
  

• Optics-Grade Surface Quality: The wafer is engineered and polished to achieve an optics-grade surface with sub-nanometer roughness and minimal sub-surface damage. This is essential for applications requiring high-fidelity wavefront control, minimal scatter, and high laser-induced damage threshold (LIDT).
