Our division offers various special material gases used in the semiconductor manufacturer of integrated circuits, flash drives, LCD, and solar cells; standard gas, which is essential for gas analysis; and industrial and other chemicals that use sulfuric gases as a raw material. Our division also offers oxygen and nitrogen production equipment based on the pressure swing adsorption (PSA) method and recovers and purifies various gasses such as hydrogen, helium, and CO2. In particular, in regard to special material gases for semiconductors, our division has set up manufacturing and sales hubs in Taiwan, South Korea, and China to meet the needs of our customers.
