Production of wafers and optical fibers

Oxygen is available in several intermediate purities, up to ultra-pure O₂ 99.9999% in bulk and compressed form, thanks to a dedicated purification plant. Nitrogen and argon come from air separation units using a cryogenic process. Helium is distributed as liquid in bulk, liquid in dewars and compressed in cylinders, cylinder bundles and tube trailers, with an ongoing commitment to diversifying sources to ensure continuity of supply.

From carbon monoxide to ammonia, both purified in-house in electronic grade, SIAD covers the most critical specialty gases for semiconductors. Through partnerships with leading players in the chemical industry worldwide, it also supplies rare gases, isotopes, fluorinated gases, acids and other process gases.

Thanks to the laboratory’s expertise, SIAD supplies different types of mixtures used in semiconductor manufacturing processes: mixtures based on hydrides or fluorinated gases, O₂/He or He/N₂ mixtures, laser mixtures and mixtures with rare gases.

Pentatec provides analysis instruments and systems for controlling the purity of gas flows, including systems for ultra-pure gases and quality control automation. Electronic gases are available in a wide range of packaging, from small cylinders to tube trailers (CO, H₂), dewars (He, N₂) and tanks (Ar, CO₂, He, N₂, O₂). SIAD also provides dedicated cylinders and materials for customers in the electronics industry.
