Toagosei Announces the Expansion of High-purity Liquid Hydrogen

Chloride Manufacturing Facilities

Toagosei Co., Ltd. announced today as follows that it has decided to expand its high-purity liquid hydrogen chloride manufacturing facilities at its Yokohama Plant.

Toagosei's high-purity liquid hydrogen chloride is widely used as a chemical used in semiconductor manufacturing because of its high quality and stable supply. Semiconductor demand is expected to recover in the second half of 2024. It is also anticipated there will be sustained growth in semiconductor demand over the long-term after that. Therefore, Toagosei is continuing to expand its manufacturing facilities. Toagosei recently received a subsidy according to the Yokohama Business Location Promotion Ordinance. In response to that, it has decided to introduce facilities based on cutting-edge manufacturing technology which optimizes manufacturing conditions and improves efficiency. Toagosei's aim in introducing these facilities is to enable the manufacturing of even more high-quality and high-purity liquid hydrogen chloride than ever before.

Toagosei has established the semiconductor and electronic materials field as one of its priority fields in its 2025 Medium-Term Management Plan. It will continue to strengthen its products for semiconductors and electronic materials and to contribute to the innovation of information infrastructure technology.
