Applications of SiC Ceramic Boat 

1. Semiconductor Manufacturing
✔ Diffusion & Annealing Furnaces
- High-Temperature Stability – Withstands 1,600°C (oxidizing) / 1,950°C (inert) without deformation.
- Low Thermal Expansion (4.3×10⁻⁶/K) – Prevents wafer warpage in rapid thermal processing (RTP).

✔ CVD & Epitaxy (SiC/GaN Growth)
- Gas Corrosion Resistance – Inert to SiH₄, NH₃, HCl, and other aggressive precursors.
- Particle-Free Surface – Polished (Ra <0.2μm) for defect-free epitaxial deposition.

✔ Ion Implantation
- Radiation-Hardened – No degradation under high-energy ion bombardment.

2. Power Electronics (SiC/GaN Devices)
✔ SiC Wafer Processing
- CTE Matching (4.3×10⁻⁶/K) – Minimizes stress in 1,500°C+ epitaxial growth.
- High Thermal Conductivity (160 W/m·K) – Ensures uniform wafer heating.

✔ GaN-on-SiC Devices
- Non-Contaminating – No metal ion release vs. graphite boats.

3. Photovoltaic (Solar Cell) Production
✔ PERC & TOPCon Solar Cells
- POCl₃ Diffusion Resistance – Withstands phosphorus doping environments.
- Long Service Life – 5-10 years vs. 1-2 years for quartz boats.

✔ Thin-Film Solar (CIGS/CdTe)
- Corrosion Resistance – Stable in H₂Se, CdS deposition processes.

4. LED & Optoelectronics
✔ Mini/Micro-LED Epitaxy
- Precision Slot Design – Holds fragile 2"–6" wafers without edge chipping.
- Cleanroom-Compatible – Meets SEMI F57 particle standards.

5. Research & Specialty Applications
✔ High-Temp Material Synthesis
- Sintering Aids (e.g., B₄C, AlN) – Chemically inert in 2,000°C+ environments.
- Crystal Growth (e.g., Al₂O₃, ZnSe) – Non-reactive with molten materials.
