SiC Coated ICP Etching Susceptor

The SiC Coated ICP Etching Susceptor is a critical plasma contact component specifically engineered for advanced ICP (Inductively Coupled Plasma) etching processes in semiconductor manufacturing. Within the high-density plasma environment where process stability, thermal uniformity, and contamination control directly dictate yield and device performance, the graphite susceptor serves as the fundamental interface between the wafer, plasma, and thermal management system.

Semixlab Susceptors utilize high-purity semiconductor-grade isostatic graphite material coated with a dense Silicon Carbide layer. This structure combines graphite's superior thermal conductivity and machinability with SiC's exceptional plasma corrosion resistance and chemical inertness. The resulting robust solution withstands high RF power, corrosive halide-based chemicals, and intense ion bombardment common in ICP etching processes.

Within the ICP etch chamber, the graphite susceptor plays a central role in wafer positioning, temperature control, and process repeatability. It provides precise mechanical support for wafers while enabling efficient heat transfer to support rear helium cooling and stable temperature regulation. Uniform thermal behavior across the wafer surface is critical for maintaining consistent etch rates, critical dimension (CD) uniformity, and profile control—especially in high aspect ratio and anisotropic etching applications. The SiC coating minimizes localized temperature fluctuations and reduces plasma-induced degradation.

From a plasma interaction perspective, the SiC coating serves as a highly durable barrier against fluorine- and chlorine-based plasmas commonly used for etching silicon, dielectrics, and wide bandgap materials. Compared to uncoated graphite or traditional ceramic materials, its low corrosion rate and high resistance to micro-arcing significantly extend component lifespan. Simultaneously, the dense SiC layer suppresses particle generation and metal contamination, meeting stringent cleanliness requirements in advanced semiconductor fabs while supporting higher overall equipment uptime and mean time between failures (MTBF).

The SiC Coated ICP Etching Susceptor embodies Semixlab Technology's profound understanding of plasma etching physics, materials engineering, and semiconductor manufacturing requirements. By integrating high-purity Graphite Susceptors with advanced SiC Coating technology, the Silicon Carbide Coated ICP Etching Susceptor delivers a balanced solution that effectively enhances process stability, extends component lifespan, and supports the continuous advancement of ICP etching technology.
