TaC vs SiC Coated Graphite Susceptor for PVT & Epitaxy

High-performance TaC (tantalum carbide) and CVD SiC (silicon carbide) coated graphite susceptors and wafer carriers designed for semiconductor PVT crystal growth and MOCVD epitaxy systems.

Key Advantages & Technical Specifications:
- Substrate: High-purity isostatic graphite with low ash content (< 5 ppm)
- Coating Options: Chemical Vapor Deposition (CVD) SiC coating or ultra-high temperature TaC coating
- Thermal & Chemical Resistance: Excellent resistance to harsh H2, NH3, and halogen process atmospheres up to 2200°C (TaC) and 1600°C (SiC)
- Reduced Particle Contamination: Eliminates graphite particulate flaking and carbon outgassing
- Applications: SiC / GaN single crystal growth crucibles, MOCVD planetary susceptors, satellite wafer carriers, RTP thermal zones
