Among the hundreds of processes in semiconductor chip manufacturing, the quality of ultra-pure water directly affects the yield of wafers, the performance and reliability of devices. Its purity requirements reach the limit of nature - the resistivity must be stable at 18.2 MΩ.cm, and there are nearly strict standards for total organic carbon, dissolved oxygen, particles, and bacterial content. Baihuipu Environmental Protection, as the top electronic-grade ultra-pure water equipment manufacturer in China, with its advanced production facilities and rigorous quality control system, ensures that each set of semiconductor ultra-pure water equipment exported to Australia can meet and exceed the highest international standards set by SEMI, ASTM, etc.
How does the Baohupu ultra-pure water system meet the most demanding requirements of semiconductor manufacturing?
Our system employs a mature and stable "three-stage processing" technology, with each stage specifically designed to achieve ultimate purity:
1. Pre-treatment and primary desalination
Objective: Remove over 99% of ions and most organic substances from the raw water.
Process: Multi-media filtration, activated carbon adsorption, two-stage reverse osmosis, equipped with a complete chemical cleaning and sterilization unit, providing the best inlet water conditions for subsequent advanced treatment.
2. Advanced treatment and deep ion removal
Objective: To enhance the water quality to the megohm level.
Core technology: Electrodeionization. Baohupu uses high-performance EDI modules. Under the action of a direct current field, it achieves deep removal of ions and continuous purification of water. No need for acid-base regeneration, and the operation is environmentally friendly and stable.
3. Final polishing and final refinement
Objective: To reach the theoretical limit of 18.2 MΩ.cm and strictly control TOC, particles and microorganisms.
Process: Precision polishing of mixed bed, membrane degassing, ultraviolet oxidation, and terminal ultrafiltration. This process is carried out in a modular assembly manner within the dust-free production workshop of Baohupu, minimizing external contamination to the greatest extent.
The outstanding quality assurance of the Baohupu production factory
Cleanroom assembly environment: The core polishing unit and the pipeline are assembled and welded in an ISO Class 7 or higher cleanroom to prevent external particle contamination.
Materials and Process: All the pipes are made of 316L or higher grade electro-polished stainless steel, and are welded using an automatic track system to ensure smooth inner walls without any dead corners, thereby inhibiting the growth of bacteria.
Fully automatic intelligent control: The system is equipped with an advanced SCADA control system, enabling 24/7 continuous monitoring, data recording and alarm functions, supporting remote access, and meeting the intelligent management requirements of Australian customers.
The advantages specifically tailored for the Australian market
Standard compliance: The system design and manufacturing fully comply with local electrical, safety and water quality standards in Australia.
High reliability design: The system fully takes into account the volatility of the power grid and water sources in some areas of Australia. It has strong shock resistance capabilities and backup designs to ensure the uninterrupted operation of the chip production line.
Quick response service: Relying on local partners, we offer prompt installation guidance, debugging services, and long-term operation support to ensure the best performance throughout the system's lifecycle.
