Mitsubishi Chemical Group (MCG Group) has decided to increase its production capacity of Mitsubishi Synthetic Silica, a synthetic silica powder used in the semiconductor manufacturing process at the Kyushu-Fukuoka Plant. Operations are scheduled to start in September 2028.

The product is a synthetic silica powder characterized by its ultra-high purity, and is employed as a raw material for quartz crucibles used in the production of semiconductor silicon (ingots) and for high-purity quartz parts in semiconductor manufacturing equipment.

The surface of the quartz crucible must be extremely pure, particularly during the ingot manufacturing process, to prevent the inclusion of impurities that can significantly degrade wafer quality. The Product boasts high competitiveness in this application by achieving the world's highest level of purity for sand-type silica using manufacturing technology cultivated over many years.

The decision to increase production capacity was made in order to meet demand from the continued growth of the semiconductor market.
