While diamond abrasives offer slightly superior hardness, our LED-grade Silicon Carbide provides several distinct advantages for sapphire substrate processing: significantly lower cost-per-wafer (typically 70-80% less), better control of surface texture for light extraction optimization, reduced risk of contamination, and superior compatibility with wet processing environments. The controlled friability of our SiC creates fresh cutting edges during use, resulting in more consistent material removal rates across large wafer surfaces. For most LED manufacturing processes, our specialized SiC formulations deliver superior cost-performance while maintaining the surface quality requirements for high-efficiency devices. Diamond abrasives may still be preferred for final polishing in certain ultra-premium applications where cost is less critical than achieving sub-nanometer surface finish.
Yes, our LED-grade Silicon Carbide abrasives can directly enhance light extraction efficiency through precisely controlled surface texturing. By creating an optimized microscale roughness profile on sapphire substrates, our SiC abrasives reduce total internal reflection at material interfaces, allowing more photons to escape the LED structure. Independent testing shows a 12-15% improvement in light output compared to conventional processing methods. The key to this enhancement is our tightly controlled particle size distribution and customized process parameters, which create the ideal surface morphology for specific LED designs. This improvement translates directly to brighter LEDs with the same power input or reduced power consumption for equivalent brightness—both critical factors in energy efficiency and device performance. Our technical team can work with your engineers to develop specific surface profiles optimized for your LED architecture.
