Specialty & Electronic Gases
High-purity gases for etch, deposition and lithography
Semiconductor manufacturing consumes dozens of ultra-high-purity gases for etching, deposition, doping and lithography, supplied mainly by industrial-gas majors Air Liquide, Linde, Air Products, Merck (EMD) and Taiyo Nippon Sanso. Certain gases — notably neon and other rare gases used in DUV/lithography lasers — have concentrated, geopolitically exposed supply. Disruptions in this layer directly stall wafer fabrication regardless of tool or wafer availability.
