Electronics & Semiconductor Filtration Solutions
- Ultra-pure filtration is critical in electronics and semiconductor manufacturing.
- Submicron particles, colloids, and metal ions in DI water and chemicals can cause circuit defects, wafer scratches, and yield loss. Strict control of contamination is essential for cleanroom operations.

- The electronics and semiconductor industry demands ultra-high purity and stringent particle control. Submicron particles and metal ions in process water (WFI, DI water) and chemicals can cause circuit defects, wafer scratches, and reduced yields. High-purity membrane filters remove fine particles and colloids, while ion-exchange and adsorptive filters minimize metal ions and organic contaminants.
- For chemicals such as photoresists, developers, and etchants, chemically resistant filter materials like PTFE, PVDF, and PES are used to ensure stability. Tank and pipeline vent filters prevent external contamination and help maintain cleanroom conditions, while final 0.05 µm membrane filters eliminate ultrafine particles to ensure maximum product reliability.
