Producer
Matheson (TNSC)
US specialty gas company owned by Taiyo Nippon Sanso Corporation (TNSC/Nippon Sanso Holdings, Japan). Revenue ~$2.5B (2024, US operations). Major supplier of semiconductor-grade helium (6N) to US and Asian fabs. Matheson is a key TSMC and Intel helium supplier. TNSC ownership means Matheson can access Japanese helium supply infrastructure and government-backed helium reserve programs.

Did you know2023
The same helium Matheson supplies to TSMC and Intel fabs (for cooling vacuum systems and leak detection) is also supplied to MRI machine superconducting magnets in hospitals and to the US Department of Energy's particle accelerators at Fermilab and Jefferson Lab. Semiconductor fab helium, medical MRI helium, and defense/science helium are all sourced from the same global supply of approximately 170 billion cubic feet per year, predominantly from the BLM Federal Helium Reserve in Amarillo Texas and from Qatar. When global helium supply tightened in 2022 (after a plant fire at the BLM Cliffside Storage Facility and Qatargas production disruptions), semiconductor fabs, hospital MRI operations, and particle accelerators simultaneously competed for the same constrained helium supply -- with no common awareness of their shared upstream constraint.
Matheson (TNSC) ↗Origin2023
Matheson Gas Products was founded in 1927 by Thomas Matheson in East Rutherford, New Jersey, initially supplying pure gases to the US chemical industry. For its first 60 years it was an independent US specialty gas company competing against Air Products and Air Liquide. Taiyo Nippon Sanso Corporation (TNSC), a Japanese industrial gas company majority-owned by Nippon Steel early in its history and later by Mitsubishi Chemical Holdings, acquired Matheson to gain a US specialty semiconductor gas platform. The TNSC ownership gives Matheson access to Japanese helium infrastructure and supply networks -- critical because Japan is the second-largest global helium consumer (for semiconductor manufacturing and MRI machines) and has governmental stockpile programs that give TNSC-affiliated companies preferential helium access during global shortages. An acquired American gas company provides a Japanese parent privileged access to US semiconductor fab supply chains.
