Mitsubishi Chemical Corporation has announced plans to commercialize ultra-high-purity colloidal silica designed for advanced semiconductor manufacturing. The company will construct new production facilities at its Kyushu Plant in Kitakyushu City, Fukuoka Prefecture, with commercial operations scheduled to begin in October 2028.
Colloidal silica is an important material used in surface polishing applications for silicon wafers and in chemical mechanical polishing (CMP) slurries. CMP is a critical process in semiconductor manufacturing because it helps create highly flat and defect-free wafer surfaces. As semiconductor architectures become increasingly sophisticated, manufacturers require polishing materials that can deliver high removal rates while maintaining nanoscale surface uniformity and minimizing scratches and contamination.
The newly commercialized Mitsubishi Chemical product will target these demanding requirements through an ultra-high-purity manufacturing process. The company plans to use tetramethoxysilane as an ultra-high-purity raw material, helping reduce impurities that could affect semiconductor performance and manufacturing yields.
Mitsubishi Chemical also intends to leverage its technological expertise to customize the physical characteristics of the colloidal silica according to customer requirements. Parameters such as particle size and particle density can be adjusted depending on the semiconductor material and polishing process. This flexibility could help semiconductor manufacturers optimize CMP performance for increasingly complex wafer and interconnect structures.
The investment comes as demand for advanced semiconductors continues to expand. Growth in generative artificial intelligence, data centers, high-performance computing and advanced telecommunications is expected to increase demand for semiconductor manufacturing materials capable of supporting next-generation chip production.
The project also aligns with Mitsubishi Chemical’s long-term management strategy, “KAITEKI Vision 35.” Under the strategy, the company has identified enabling advanced data processing and telecommunications as a key business focus. By expanding its portfolio of high-purity semiconductor materials, Mitsubishi Chemical aims to strengthen its position within the global semiconductor supply chain.
The Kyushu facility is expected to enhance the company’s ability to supply specialized polishing-material inputs to semiconductor manufacturers. However, the commercial impact will depend on production scale, customer qualification and the pace of semiconductor industry expansion before and after the facility starts operations.
Overall, the move represents a strategic expansion into a high-value semiconductor materials segment. It could strengthen Mitsubishi Chemical’s presence in CMP-related materials while supporting the industry's growing need for highly controlled, low-contamination manufacturing processes.
Product Impact and Chemical Commodity Price Impact
Mitsubishi Chemical’s ultra-high-purity colloidal silica commercialization should strengthen the company’s position in semiconductor polishing materials and improve supply availability for advanced CMP applications. The project is unlikely to create an immediate major change in colloidal silica prices because commercial production is planned for October 2028. Over the longer term, additional capacity could moderate supply tightness and limit price increases if demand remains balanced. Demand for high-purity tetramethoxysilane, silica-based materials and semiconductor-grade processing chemicals could increase as production ramps up. However, the impact on broader chemical commodity prices tracked by ChemAnalyst should remain limited, with semiconductor-related specialty chemicals seeing stronger demand than bulk chemical markets.
