Kalrez Seals Reduce Contamination in critical Semiconductor Wafer Fabrication Processes
Reducing contamination from particles, metallic contaminants and outgassing caused by seal deterioration are major goals of semiconductor fabricators. Perfluoroelastomers (FFKMs) are used in deposition processes due to their extraordinary chemical resistance and thermal stability. Kalrez® 9100 is designed to help reduce the potential for contamination while maintaining sealing functionality in aggressive plasma environments.
