In semiconductor manufacturing workshops, high-purity chemicals are kept in continuous circulation. A large volume of acids and organic solvents are adopted in wafer cleaning, etching and other processes. These chemicals need to be delivered from supply systems to various process equipment through pipelines. Along this route, tubing is one of the components that stays in contact with chemicals for the longest time.
The cleanliness of pipeline materials directly affects the quality of chemicals. If metal ions leach out or particles are released from the pipeline, the chemicals will be secondarily contaminated during transfer, which reduces wafer yield. More advanced manufacturing processes impose stricter requirements on pipelines. For this reason, Ultra-Clean PFA Tube serves as a critical component of high-purity fluid delivery systems.
BSL designs professional Ultra-Clean PFA Tube products tailored for high-purity fluid transfer scenarios. Featuring high cleanliness, superior physical properties and advanced cleaning processes, these products enable contamination-free transfer of high-purity fluids.
Advantage 1: Low Metal Ion Leachability to Safeguard Purity for Advanced Nodes
Metal ions constitute one of the primary sources of chemical contamination. Ultra-Clean PFA Tube is manufactured from high-purity PFA raw materials via high-temperature and high-pressure extrusion, minimizing impurity introduction at the source. Immersion tests with high-purity chemicals such as hydrochloric acid verify that the leaching levels of key ions including sodium, aluminum and iron comply with SEMI F57 limits, offering an extra safeguard for wafer yield.
Advantage 2: Smooth Inner Wall for Low Particle Generation
The surface roughness of the pipeline inner wall directly governs particle adhesion and retention inside the tubing. Fabricated by precision extrusion, Ultra-Clean PFA Tube features an inner surface roughness Ra ranging from 112 nm to 126 nm with smooth and even tube walls. In online UPW (ultra-pure water) testing, the count of critical particles ≥0.2 μm remains extremely low. Low particle levels help reduce defects on wafer surfaces, cut particle accumulation within pipelines, and stabilize the delivery of high-purity fluids.
Advantage 3: Real-Time In-Line Monitoring for Dimensional Stability
Dimensional stability of tubing determines connection tightness and flow consistency. During production, BSL carries out in-line monitoring of tube wall thickness and outer diameter, with real-time data transmitted to the central control system. Automatic alerts trigger once readings exceed threshold values. The wall thickness variation is controlled within ±0.1 mm, while the measured outer diameter deviation stays within ±0.05 mm to guarantee high precision. This facilitates smooth assembly and connection for customers and mitigates leakage risks during long-term operation.
Advantage 4: Outstanding Chemical Resistance with Customization Support
Benefiting from the stable molecular structure of PFA, Ultra-Clean PFA Tube can withstand long-term exposure to strong acids, strong alkalis and organic solvents, covering a wide range of high-purity chemical transfer applications. Customization services including tube specifications and cut lengths are available for customers with special working conditions to match their piping construction plans.
Contamination-free transfer of high-purity fluids relies on consistent quality across every link. BSL implements full-process control covering raw materials, manufacturing processes and testing to sustain stable performance of Ultra-Clean PFA Tube. Serving precision manufacturing sectors such as semiconductors, BSL delivers dependable products and responsive support for customer production, and collaborates with industrial chain partners to advance the localization of key materials.
