VET Energy Supplies High-Purity Graphite Susceptors for Semiconductor Manufacturing

Ningbo VET Energy Technology Co., Ltd., based in China, is now supplying high-purity graphite susceptors essential for advanced semiconductor manufacturing. These components are primarily utilized in Chemical Vapor Deposition (CVD) and Metal-Organic Chemical Vapor Deposition (MOCVD) processes, critical for producing next-generation materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN).

The graphite susceptors act as precision-engineered carriers designed to hold semiconductor wafers securely within the high-temperature and corrosive environments of reaction chambers. Typically constructed from high-purity isostatic graphite, they are often coated with a dense layer of Silicon Carbide (SiC) via Chemical Vapor Deposition. This SiC coating prevents particle generation from the graphite and shields it from aggressive process gases, maintaining the high purity required for semiconductor fabrication.

VET Energy's susceptors are engineered to withstand temperatures exceeding 1500°C and facilitate uniform thermal distribution across the wafer surface. This thermal uniformity is crucial for achieving consistent epitaxial layer quality, directly impacting the performance and reliability of fabricated semiconductor devices. The company employs advanced multi-axis CNC machining to create intricate wafer pockets and aerodynamic channels, tailoring the susceptors to specific reactor designs and process requirements.

The use of these specialized graphite susceptors supports the production of high-performance semiconductor components, particularly for applications in power electronics and LEDs that demand materials like SiC and GaN. VET Energy highlights the precision, durability, and chemical inertness of its products as key benefits for demanding semiconductor manufacturing environments.
