Producer
Linde Electronics (formerly Praxair Specialty Gases)
Linde Electronics (the semiconductor gases division of Linde plc) is the second-largest global WF₆ producer. Revenue of semiconductor gases division ~$4B (est. 2024). Produces WF₆ at Alfa (NJ) and international facilities. Linde Electronics is one of only 3–4 qualified WF₆ suppliers globally. Post-merger integration of Praxair's specialty gas business expanded Linde's WF₆ capacity. Supplies TSMC, Intel, Samsung, and GLOBALFOUNDRIES on multi-year contracts.

Did you know2021
Linde simultaneously supplies liquid oxygen keeping intensive care patients alive in hospitals AND tungsten hexafluoride (WF6) enabling the tungsten via contacts in TSMC's logic chips AND hydrogen for fuel cell vehicles AND atmospheric nitrogen for food packaging. The same Linde bulk gas plants at Clifton NJ or Clinton MA that fill hospital oxygen tanks also fill the semiconductor fab gas cylinders and the food processing liquid nitrogen tanks. When COVID created a surge in hospital oxygen demand in 2020-2021 (particularly in India and Brazil), Linde and Air Products faced decisions about allocating liquid oxygen production between hospital patients and industrial customers -- the same industrial gas infrastructure was simultaneously a life-support system and a manufacturing input.
Linde plc ↗Origin2023
Linde plc traces its origins to Carl von Linde, the German engineer who in 1879 patented the first practical refrigeration machine and in 1895 developed the first industrial process for liquefying air -- separating atmospheric oxygen and nitrogen at large scale. Von Linde's industrial gas business became Linde AG, one of Germany's premier industrial companies. Praxair, which merged with Linde in 2018 to form the world's largest industrial gas company, traced its lineage to Union Carbide's Linde Air Products division (named after the German company whose technology it licensed). The combined entity became Linde plc with ~$33B revenue and operations in 100+ countries. Linde Electronics, the semiconductor specialty gas division, emerged from Praxair's acquisition of various specialty gas businesses including MEMC Electronic Materials' specialty gas operations. The company that invented the science of industrial gas separation in 1895 Germany now supplies the hyperpure gases without which TSMC cannot manufacture transistors.
