Following a processing facility and sales office for optical functional films established in Shanghai in 2001, Sumitomo Chemical has reinforced its business base for IT-related chemicals in China over the years in order to provide fine-tuned response to customers’ specific needs. The business base is currently at eight locations throughout the country including Beijing and Wuxi. At these locations, Sumitomo Chemical manufactures and sells polarizing films for LCD panels or high-purity chemicals for semiconductors.
High-purity chemicals for semiconductors are mainly used for precision cleaning in semiconductor micromachining. Demand for high-purity chemicals for semiconductors is expected to grow sharply in the years to come.
