Sapphire offers the highest strength, purity, and durability in aggressive process environments using NF3 and CF4 .Sapphire components provide long lifetimes, reduced particulation and increased uptime.
Sapphire components used in a range of Semiconductor Equipment Applications:

• Sapphire tubes– replacing quartz, sapphire plasma tubes have proven to be an enabling technology
• Plasma injector nozzles – replacing ceramic and quartz, Sapphire Injectors proven to reduce particulation, increase time between PM’s, increased uptime, and reduced COO
• Sapphire Chamber Windows – offering very long life and consistent transmission
• Heater and Microwave windows – providing high transmission and long life
• Sapphire Lift pins and guide/alignment pins – dramatically improves strength over quartz versions, with no erosion over time. Dramatic improvement in particle performance over ceramic versions.
• Optical light guides and sensor probes – usable to temperatures above quartz devitrification limit, and in hostile chemical environments
• Thermocouple protection sheaths – replacing quartz and silicon carbide (SiC) for multi point thermocouples used in horizontal and vertical furnaces.
• Gas delivery/showerhead components – long life in aggressive plasma
• Sapphire dummy wafers
