In the semiconductor field, the stability of each component is very important for the whole process. However, in a high-temperature environment, graphite is easily oxidized and lost, and SiC coating can provide stable protection for graphite parts. In the Semicera team, we have our own graphite purification processing equipment, which can control the purity of graphite below 5ppm. The purity of the silicon carbide coating is below 0.5 ppm.

Epitaxy Growth Susceptor
Silicon/silicon carbide wafers need to go through multiple processes to be used in electronic devices. An important process is silicon/sic epitaxy, in which silicon/sic wafers are carried on a graphite base. Special advantages of Semicera's silicon carbide-coated graphite base include extremely high purity, uniform coating, and extremely long service life. They also have high chemical resistance and thermal stability.
LED Chip Production
During the extensive coating of the MOCVD reactor, the planetary base or carrier moves the substrate wafer. The performance of the base material has a great influence on the coating quality, which in turn affects the scrap rate of the chip. Semicera's silicon carbide-coated base increases the manufacturing efficiency of high-quality LED wafers and minimizes wavelength deviation. We also supply additional graphite components for all MOCVD reactors currently in use. We can coat almost any component with a silicon carbide coating, even if the component diameter is up to 1.5M, we can still coat with silicon carbide.
Semiconductor Field, Oxidation Diffusion Process, Etc.
In the semiconductor process, the oxidation expansion process requires high product purity, and at Semicera we offer custom and CVD coating services for the majority of silicon carbide parts.
The following picture shows the rough-processed silicon carbide slurry of Semicea and the silicon carbide furnace tube that is cleaned in the 1000-level dust-free room. Our workers are working before coating. The purity of our silicon carbide can reach 99.99%, and the purity of sic coating is greater than 99.99995%.
