Special Coating
Si epitaxial graphite carrier tray
Si epitaxial graphite substrates exhibit excellent thermal stability, chemical inertness, and cleanliness, ensuring uniform growth of the epitaxial layer and high wafer yield.
The silicon carbide boat is the core supporting component in the wafer oxidation and diffusion process, primarily used to hold silicon wafers. It demands extremely high purity—exceeding 99.999%—and the content of metallic particles must be strictly controlled.
Epitaxial Graphite Substrates for the LED Industry
The CVD-SiC coating deposited on the graphite substrate exhibits a high thermal expansion coefficient match with the graphite base material, boasts excellent resistance to acid and alkali corrosion, effectively prevents graphite powdering and corrosive damage, and extends the service life of the substrate.
Silicon Carbide Coated Graphite Components for SiC Epitaxy
It primarily addresses high‑temperature corrosion and contamination—such as the tendency of conventional graphite to oxidize and pulverize in oxygen‑containing environments. In etching processes, SiC coatings resist corrosive gases like Cl₂ and CF₄, protecting the chamber structure. This reduces the risk of particle shedding, extends component lifetimes by 3–5 times, and lowers equipment maintenance costs.
Silicon carbide–coated heating wires are indispensable components in single‑crystal silicon pulling furnaces, polycrystalline silicon ingot casting furnaces, high‑temperature industrial furnaces, and laboratory equipment.
