TaC coating graphite is created by coating the surface of a high-purity graphite substrate with a fine layer of tantalum carbide by a proprietary Chemical Vapor Deposition (CVD) process.The advantage is showed in below picture:

The tantalum carbide (TaC) coating has gained attention due to its high melting point of up to 3880°C, excellent mechanical strength, hardness, and resistance to thermal shocks, making it an attractive alternative to compound semiconductor epitaxy processes with higher temperature requirements, such as Aixtron MOCVD system and LPE SiC epitaxy process.It also has a wide application in PVT method SiC crystal growth process.

Silicon Carbide Coating

VeTek Semiconductor specializes in the production of ultra pure Silicon Carbide Coating products, these coatings are designed to be applied to purified graphite, ceramics, and refractory metal components.

Our high purity coatings are primarily targeted for use in the semiconductor and electronics industries. They serve as a protective layer for wafer carriers, susceptors, and heating elements, safeguarding them from corrosive and reactive environments encountered in processes such as MOCVD and EPI. These processes are integral to wafer processing and device manufacturing. Additionally, our coatings are well-suited for applications in vacuum furnaces and sample heating, where high vacuum, reactive, and oxygen environments are encountered.

At VeTek Semiconductor, we offer a comprehensive solution with our advanced machine shop capabilities. This enables us to manufacture the base components using graphite, ceramics, or refractory metals and apply the SiC or TaC ceramic coatings in-house. We also provide coating services for customer-supplied parts, ensuring flexibility to meet diverse needs.

Our Silicon Carbide Coating products are widely used in Si epitaxy, SiC epitaxy, MOCVD system, RTP/RTA process, etching process, ICP/PSS etching process, process of various LED types, including blue and green LED, UV LED and deep-UV LED etc.,which is adapted to equipment from LPE, Aixtron, Veeco, Nuflare, TEL, ASM, Annealsys, TSI and so on.
