8-inch Teflon Wafer Cassette - PFA

Built to withstand chemical exposure in advanced wafer cleaning processes

PFA wafer cassettes are designed for the safe transfer, storage, and cleaning of semiconductor wafers in corrosive chemical environments and high-temperature wet process applications. Manufactured from premium perfluoroalkoxy (PFA) or Teflon resin, these wafer carriers provide exceptional resistance to strong acids, hydrofluoric acid, alkaline solutions, and continuous exposure to temperatures up to 220 °C without deformation, degradation, or ionic contamination.

The smooth, translucent surfaces minimize particle generation, simplify cleaning, and maintain wafer integrity throughout critical manufacturing steps. PFA wafer cassettes are compatible with standard wafer processing tools, wet benches, and SMIF/FOUP interface systems, enabling direct transfer between acid baths, wafer etchers, and inspection equipment. Their outstanding chemical resistance, dimensional stability, and ultra-clean design make them ideal for wafer cleaning, etching, and high-temperature processing in advanced semiconductor fabs.
