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 Silicon Wafer Carrier for many years. Our Silicon Wafer Carrier 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.
Semiconductor deposition processes use a combination of volatile precursor gases, plasma, and high temperature to layer high quality thin films onto wafers. Deposition chambers and wafer handling tools need durable ceramic components to stand up to these challenging environments.
Semicorex Silicon Wafer Carrier is high-purity silicon carbide, which has high corrosion and heat resistance properties as well as excellent thermal conductivity.

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
