STI (Systems Technology Inc.) has so far accumulated high reputation in global market for its state-of-the-art chemical delivery systems(CDSs). Keeping such international certifications as ISO 14001 and ISO 9001 and maintaining several overseas offices, STI has shown gradually growing export performance, mainly to China, Taiwan, Malaysia, Singapore, and the United States markets. Currently, the venture holds many attractive hot-selling CDSs - mixing & supply systems, slurry supply systems and chemical delivery systems. Among them, the mixing&supply systems are major players in expanding the global market’s presence of the company. The fully automatic mixing & supply system features monitoring chemical concentration, flow rate and supply pressure. It is favored in the mixing and supply process for semiconductor, TFT LCD, and photovoltaic factories. Now, developers of various chemicals including TMAH, DHF, and KOH prefer them. STI’s slurry supply system is also major one of the CDSs, which is designed for CMP (Chemical Mechanical Planarization) process. With the fully automatic systematic functions, it effectively dilutes slurries with water and mixes them with other chemicals. It also exceptionally monitors conductivity, flow rate and pressure. Its chemical supply is controlled by loop flow. All of its chemical delivery systems ensure no metal contamination and no particle generation.
