Qnity Electronics Introduces Kalrez 7080 Sealing Parts for Chip Processing

Qnity Electronics introduced Kalrez 7080 perfluoroelastomer sealing parts, engineered for semiconductor processes operating at temperatures up to 330°C. In internal thermal-aging evaluations over 672 hours of air exposure at temperatures up to 325°C, the parts showed thermal stability, with ultra-low outgassing and extremely low metallic contamination. Target applications include diffusion, oxidation, thermal ALD, metal CVD and LPCVD, and the parts will be shown at SEMICON West, October 13-15, in San Francisco.

Key facts

Market context

Perfluoroelastomers such as the Kalrez family are fully fluorinated elastomers valued for holding their shape and sealing properties under aggressive chemistry and high heat, where ordinary rubbers degrade. Their main use is in O-rings, gaskets and other seals for process equipment. Semiconductor fabrication is the dominant demand driver: wafer tools for diffusion, oxidation, deposition and etch rely on seals that must resist reactive gases and avoid releasing particles or metallic contaminants that could reduce chip yields. Demand also follows wafer-fab capacity additions and the growing number of advanced packaging and thermal management processes. Because qualified sealing materials are difficult to swap once a tool is validated, suppliers with proven high-temperature grades tend to keep long-term positions with equipment makers and fabs. New grades can therefore shift share among perfluoroelastomer producers and influence pricing for specialty fluoropolymer compounds, which typically command premiums over commodity elastomers.
