Semicorex provides semiconductor-grade ceramics for your OEM semi fabrication tools and wafer handling components focusing on silicon carbide layers in semiconductor industries. We have been manufacturer and supplier of Wafer Carrier Tray for many years. Our Wafer Carrier Tray has a good price advantage and cover most of the European and American markets. We look forward to becoming your long-term partner in China.
Not only for thin film deposition phases such as epitaxy or MOCVD, or wafer handling processing, Semicorex supplies ultra-pure ceramic carrier used to support wafers. At the core of the process, the SiC Wafer Boat, Wafer Carrier, Wafer Holder for the MOCVD, are first subjected to the deposition environment, so it has high heat and corrosion resistance. The SiC coated carrier also has a high thermal conductivity, and excellent heat distribution properties.

The difference between SSiC and RBSiC:
1. Sintering process is different. RBSiC is to infiltrate free Si into silicon carbide at a low temperature, SSiC is formed by natural shrinkage at 2100 degrees.
2. SSiC have smoother surface, higher density and higher strength, for some sealings with more strict surface requirements, SSiC will be better.
3. Different used time under different PH and temperature, SSiC is longer than RBSiC
