Semiconductor gas

We will introduce gases essential for semiconductor manufacturing, such as ICs, memory, LCDs, and solar cells!

Since developing semiconductor-grade high-purity NH3 for the first time in the 1970s, our company has been applying the gas synthesis and purification technologies cultivated as a comprehensive chemical manufacturer to produce a wide variety of ultra-high-purity gases. These gases are used in various semiconductor manufacturing processes such as film formation (CVD, ALD), etching, doping, and epitaxial growth. Everyday electronic devices like smartphones, displays, and solar cells are equipped with numerous semiconductor products, including ICs, memory, and power semiconductors. Sumitomo Seika contributes to people's enriched lives by providing high-purity, high-quality gases in a stable manner. 【Product Lineup (Partial)】 ■NH3 Ammonia ■N2O Nitrous Oxide ■CO Carbon Monoxide ■NO Nitric Oxide *For more details, please refer to the related links or feel free to contact us.
