Hiner-pack® 4-inch Teflon Wafer Cassette - PFA
Description:
Designed for Wafer Handling in Corrosive or High-Temperature Semiconductor Processes
Engineered for extreme semiconductor manufacturing conditions, PFA wafer cassettes excel in wafer transfer, storage, and wet process cleaning. Constructed from premium perfluoro alkoxy (PFA) or Teflon resin, they offer exceptional resistance to strong acids, hydrofluoric acid, and caustic chemicals, maintaining structural integrity at continuous operating temperatures up to 220 °C. The cassette’s smooth, translucent finish minimizes particle release, simplifies cleaning, and ensures wafer protection throughout processing. Designed to integrate with wafer etchers, wet benches, and SMIF/FOUP-compatible tools, these corrosion-resistant wafer carriers provide reliable, contamination-free handling for high-purity wafer cleaning, etching, and thermal applications in leading semiconductor fabs.
- Inert PFA/Teflon resists strong acid/base and HF corrosion
- Withstands temperatures up to approximately 220 °C without degradation or deformation
- Smooth/translucent surface simplifies cleaning
- Supports customization (handles, laser engraving, RFID)
Application
- Handling wafers in high-temperature or corrosive wet processes
- Use in chemical baths for wafer cleaning or etching
- Storage of wafers in environments requiring chemical resistance
- Long-term use in fabs due to superior durability and purity
