Request Custom Wet Process Technical Consultation Does KOSEN SEMI support non-standard customization for 8-inch and 12-inch wafer cleaning equipment?
Yes, KOSEN SEMI specializes in non-standard, OEM custom wet process equipment for both 200mm (8-inch) and 300mm (12-inch) wafer manufacturing lines. We design modular automated wet benches, semi-automated tools, and single-wafer scrubbers specifically tailored to your fab layout, cleanroom footprint, and target throughput.
Custom engineering options include specialized chemical bath sizing, variable megasonic frequency integration, custom wafer carriers and end-effectors, ultra-clean drying modules (such as IPA vapor dryers), and bespoke robotics designed for delicate compound semiconductors like SiC, GaN, and GaAs.
What brand and quality level of critical components are used in KOSEN SEMI wet processing systems?
We partner exclusively with top-tier international semiconductor component manufacturers for all critical wetted flow components, precision sensors, and fluid management systems. Key components—such as magnetic levitation chemical pumps, high-purity PFA valves, ultrasonic flow meters, and optical liquid level sensors—are sourced from premier industry suppliers.
Utilizing high-purity fluoropolymer wetted pathways (PTFE/PFA/PVDF) ensures complete corrosion resistance against aggressive acids and solvents. This strict selection criteria guarantees sub-ppb purity levels, minimal metallic contamination, ultra-low particle generation, and exceptional long-term MTBF (Mean Time Between Failures) during continuous 24/7 fab operations.
Which chemical media, acids, and solvents are compatible with KOSEN SEMI wet cleaning machines?
KOSEN SEMI wet bench equipment and wafer scrubbers are engineered to safely handle all standard and proprietary semiconductor cleaning, etching, and stripping chemistries. Fully compatible chemical media include:
- Hydrofluoric acid (HF) and buffered oxide etch (BOE) solutions
- Sulfuric acid (H2SO4) and hydrogen peroxide (H2O2) SPM cleaning mixtures
- Hydrochloric acid (HCl), ammonium hydroxide (NH4OH), and SC1/SC2 cleaning reagents
- Phosphoric acid (H3PO4) for silicon nitride etching, Isopropyl Alcohol (IPA), and high-purity DI water
Each process bath is configured with material-matched seals, inline chemical concentration monitoring, precision thermal controllers, and dedicated recirculation filtration loops customized to your precise chemical recipe and operating temperatures.
How do KOSEN SEMI wet benches prevent cross-contamination between chemical baths?
To protect process integrity and maximize die yields, KOSEN SEMI wet tools utilize strict mechanical and environmental segregation. Each chemical station features dedicated exhaust ducting, double-contained chemical supply piping, isolated drain management, and automated lip exhaust systems to control chemical vapors.
Additionally, high-precision robotic transfer arms execute programmable multi-axis motion curves with liquid drip trays that catch carry-over fluid during wafer transfer between process tanks and high-purity quick-dump rinse (QDR) modules.
What automation levels and fab software integration protocols (SECS/GEM) are offered?
KOSEN SEMI supplies flexible automation tiers ranging from manual and semi-automated wet benches to fully automated, enclosed cassette-to-cassette wafer processing systems. All automated tools feature SECS/GEM (SEMI E4, E5, E30, E37) compliant software architecture for seamless integration into host Manufacturing Execution Systems (MES).
Features include dynamic recipe management, user access control levels, real-time sensor logging, predictive maintenance alarms, and secure remote diagnostic capabilities to ensure minimal downtime and full batch traceability.
