Kalrez® perfluoroelastomer parts

Semiconductor Processing Seals

Perfluoroelastomer Parts For Aggressive Semiconductor Environments

Seals for Semiconductor manufacturing

Kalrez® perfluoroelastomer parts have been field-proven in the manufacture of semiconductors where processing steps can involve extremes of both thermal and chemical exposure. Since purity is critical to high semiconductor wafer yield, reducing semiconductor seal contamination from particulates, outgassing and extractables is a major goal of semiconductor fabricators. With Kalrez®, manufacturers gain seal integrity and process purity.

Chemical resistance that is nearly universal, coupled with superior high-temperature properties, enables Kalrez® parts to withstand virtually any process media, including plasma with various gases at temperatures up to 325°C.

By selecting the product for Kalrez® parts that is best suited to a specific application, processors can improve semiconductor seal performance in all wafer-fabricating operations, including thermal, deposition, etching, ashing/stripping, and wet chemical processes.
