Wafer Fab Cleanroom Exhaust Safety System
Core Technical Advantages and Toxic Gas Abatement Capabilities
KOSEN SEMI delivers high-performance semiconductor scrubber systems engineered specifically for continuous, ultra-clean wafer fabrication operations. Combining proprietary multi-stage wet scrubbing technology with intelligent, real-time process monitoring, our point-of-use scrubber solutions yield a verified Destruction and Removal Efficiency (DRE) exceeding 99.99% across toxic, corrosive, acid, and alkaline gas streams.
Multi-Stage Wet Scrubbing with Corrosion-Resistant Fluoropolymers
Semiconductor tool exhaust carries volatile chemical combinations that degrade standard industrial equipment. KOSEN SEMI integrates advanced chemical absorption columns built using high-grade Polypropylene (PP), Polyvinylidene Fluoride (PVDF), and Perfluoroalkoxy (PFA) materials to withstand concentrated exposure to aggressive acid vapors and alkaline gases.
- ✓ Multi-Stage Packing Bed: High-density liquid-gas contact zones maximize gas neutralization rates while minimizing chemical reagent consumption.
- ✓ Corrosion Immunity: Full PVDF/PFA fluid paths prevent structural degradation from aggressive hydrofluoric acid (HF) and hydrochloric acid (HCl) exhausts.
- ✓ Smart Recirculation Loop: Automated pH and ORP dosing controls optimize neutralization efficiency and decrease liquid wastewater footprint.
Automated Safety Redundancy for Zero-Downtime Wafer Production
Unplanned fab shutdowns result in severe loss of wafer yield. Designed specifically to maintain continuous uptime, KOSEN SEMI point-of-use scrubber architectures feature built-in hardware and software fail-safes that switch operational paths instantly during component maintenance or utility interruptions. These advanced features are developed for seamless integration alongside our advanced Single Wafer Cleaning Systems.
- ✓ Dual-Pump Auto-Failover: Parallel recirculation pumps switch within milliseconds upon sensing pressure drops, ensuring uninterrupted toxic gas abatement.
- ✓ Emergency Power-Off Interlocks: Integrated SEMI S2/S8 compliant electrical safety circuits connect directly to tool emergency off (EPO) systems.
- ✓ Differential Pressure Monitoring: Continuous monitoring prevents particulate clogging in mist eliminator pads and packed towers.
