The Silicon Carbide (SiC) Ceramic End Effector is a high-precision wafer handling component designed for semiconductor automation systems, including wafer transfer robots, AMHS systems, EUV lithography equipment, and high-temperature process tools.
Made from high-purity CVD SiC or engineered SSiC, this end effector delivers exceptional rigidity, ultra-low particle generation, and outstanding thermal and chemical stability. It is widely used in 300mm and advanced node semiconductor fabs, where contamination control and positioning accuracy are critical.
Compared with traditional aluminum or quartz end effectors, SiC ceramic solutions significantly improve process stability, wafer safety, and equipment lifetime.
