Si Epitaxial Parts

CVD SiC Coated Components for Silicon Epitaxy (Si Epi)

Precision-engineered for single-wafer and batch Silicon Epitaxial deposition systems, our CVD SiC coated susceptors, satellite disks, and thermal field components deliver outstanding thermal uniformity and zero outgassing. The high-density cubic β-SiC coating layer fully encapsulates the high-purity graphite substrate, preventing reactive gas etching (SiH₄, SiH₂Cl₂, HCl) and guaranteeing ultra-low metallic impurity levels (< 5 ppm) during high-temperature Si Epi processing (1000°C - 1200°C).

Thermal Field Uniformity

Controlled emissivity ensures precise wafer edge-to-center film thickness consistency.

HCl Etch Resistance

Provides robust protection against in-situ chamber cleaning chemicals and thermal shocks.

OEM System Compatibility

Precision CNC machined to fit mainstream 200mm/300mm single-wafer Epi tools (Applied Materials, ASM).
