CVD SIC coated graphite susceptor
Semixlab CVD SiC Coated Graphite Susceptors are high-performance, drop-in replacements engineered for demanding MOCVD processes. Built on ultra-high-purity isostatic graphite and finished with a dense, uniform CVD Silicon Carbide coating, they deliver exceptional thermal stability, chemical resistance, and wafer purity control. Precision-machined to micron-level tolerances for seamless compatibility with leading systems such as Aixtron G5 and G10 reactors, these susceptors ensure uniform heat transfer, minimize defect generation, and support high-yield epitaxial growth of GaN, AlGaN, and related compound semiconductor layers for LED and power device applications.
Description
High Performance Susceptors for Critical Wafer Processing
Our Semixlab high-purity Silicon Carbide (SiC) coated susceptors are specifically engineered for the demanding environments of modern semiconductor manufacturing. Designed as seamless "drop-in" replacements for leading OEM systems, these susceptors — such as the S4-G5 for Aixtron G5 reactors and the S6-G10 for the G10 series — provide the thermal stability, material purity, and chemical resistance required for high-yield, high-quality epitaxial layer growth.
Our commitment to quality ensures that our susceptors meet or exceed the performance of OEM parts, all while offering cost-effective and legally compliant solutions.
The Semixlab Advantage: Key Technical Metrics and Benefits
OEM Compatibility and Ease of Integration
We maintain a large database of specifications, ensuring our susceptors are precision-machined for a direct, "drop-in" fit into your Aixtron reactors, minimizing downtime and simplifying maintenance. This includes accurate pocket dimensioning and wafer-edge handling features for precise processing and robotic compatibility.
Micron-Level Precision Machining
With tight tolerances down to 1 μm and overall flatness control, our susceptors ensure uniform wafer handling and gas flow dynamics across the entire process area, which is vital for maintaining film uniformity and minimizing defects on the epitaxial layer.
Exceptional CVD SiC Coating Performance
Our state-of-the-art CVD process ensures a high-density, high-purity, and uniform Silicon Carbide coating across all surfaces, including complex pockets. The coating provides:
- Low Coefficient of Thermal Expansion (CTE): Matched CTE with the graphite core minimizes thermal stress during rapid temperature cycling, significantly reducing coating delamination or cracking.
- Ultra-High Material Purity: We maintain total metallic impurities below 5 ppm, critical for preventing wafer contamination that could impact device performance, especially in high-efficiency LEDs and power devices.
- Increased Lifespan: The durable SiC coating offers exceptional resistance to the corrosive gases and high temperatures found in MOCVD processes, extending the susceptor’s useful life.
Superior Iso-static Graphite Core
Semixlab selects high-grade iso-static graphite, which provides a homogeneous structure, excellent thermal and electrical conductivity, and high mechanical strength at extreme temperatures, forming a stable and reliable foundation for the SiC coating.
Third-Party Purity Verification
Our material purity and chemical stability are verified by third-party ICP-OES testing, providing you with documented assurance of consistent quality and low contamination risk.
Optimized Solutions for MOCVD Systems
Our susceptors are not just parts; they are part of a solution to optimize the efficiency and yield of your MOCVD processes. Our commitment to continuous material and manufacturing process improvements, along with a team derived from high-profile academic research institutions (such as the Chinese Academy of Sciences), ensures that we stay at the forefront of this critical technology.
Our susceptors are ideal for numerous applications:
- Blue-Green LED Manufacturing: For the growth of high-brightness LEDs on sapphire or SiC substrates.
- Power Electronics (GaN-on-Si): For manufacturing reliable and efficient GaN-based power devices, including HEMTs.
- General III-V Epitaxy: For complex multi-junction solar cells, laser diodes, and advanced RF components.
Semixlab provides not just products, but the trust and reliability your sophisticated semiconductor facility demands.
