FAQs About ADCERAX® Silicon Carbide Wafer Handling Furnace Components
A sintered SiC wafer boat provides near-zero porosity and maintains structural accuracy at temperatures above 1400°C. This material maintains slot pitch stability, allowing diffusion furnaces to preserve wafer alignment over 500+ cycles. Its creep resistance prevents long-span deformation commonly seen in porous ceramics. As a result, Silicon Carbide Wafer Handling Furnace Components based on SSiC ensure long-term geometric reliability.
A high-purity SiC wafer boat minimizes contamination risks during oxidation and annealing processes. The absence of free silicon and impurities reduces particle shedding and surface reactions at 900–1100°C. This improves oxide film uniformity on wafers and lowers the probability of micro-scratches during thermal cycling. Therefore, high-purity configurations enhance the stability of Silicon Carbide Wafer Handling Furnace Components in PV oxidation furnaces.
A vertical diffusion furnace SiC wafer boat supports wafers in a stacked orientation that relies heavily on pitch uniformity and thermal equalization. Its SiC microstructure maintains predictable expansion behavior across 1100–1250°C. This prevents slot drift, wafer tilt, and uneven dopant diffusion. The structural rigidity strengthens the overall performance of Silicon Carbide Wafer Handling Furnace Components in vertical furnace environments.
A SiC cantilever beam provides long-span rigidity that resists bending during automated wafer loading. Its modulus above 300 GPa stabilizes wafer stacks even during rapid transport motions. This reduces vibration-induced micro-cracks and protects thin PV wafers. With these advantages, the cantilever beam becomes a critical element within Silicon Carbide Wafer Handling Furnace Components.
An advanced SiC cantilever paddle withstands ΔT up to 300°C, limiting thermal shock damage during transfer. Its low thermal expansion ensures precise wafer seating and prevents gradual deflection across many cycles. Surface inertness helps minimize particle contamination before PECVD deposition. These factors significantly improve the performance of Silicon Carbide Wafer Handling Furnace Components during pre-process heating.
SiC components retain dimensional stability due to low CTE values around 4.0–4.5×10⁻⁶/K. This allows slot pitch tolerance to remain within approximately 0.05 mm throughout repeated cycles. Stable geometry directly enhances dopant uniformity in phosphorus diffusion. The precision reduces wafer tilt and prevents edge slip during high-stress thermal stages.
High flexural strength (typically 250–450 MPa depending on grade) minimizes creep deformation. Dense SiC microstructures distribute thermal loads evenly across extended spans. The combination limits bowing effects during prolonged 900–1100°C oxidation cycles. These properties make the components stable under heavy wafer stacks.
SiC carriers maintain flatness and straightness within tight tolerances, lowering mechanical stress on thin wafers. High thermal shock resistance prevents micro-fracture initiation during rapid temperature swings. Stable seating reduces localized point loading that often leads to breakage. The result is improved mechanical survival across large-scale PV handling cycles.
