What drives the shift from liquid nitrogen delivery to on-site PSA generation in China?

The purity ceiling is the key constraint. Standard PSA tops out around 99.999%, but advanced semiconductor fabs need 6N or higher. That's why we still see liquid nitrogen dominance in leading-edge chipmaking, while PSA captures the 5N and below segment. Watch for hybrid models where PSA provides bulk supply and liquid nitrogen covers peak or ultra-high-purity demand.

Overview

Nitrogen (N₂, CAS 7727-37-9) is a colourless, odourless, inert gas that liquefies at −196°C and is slightly soluble in water. As the most abundant component of air (about 78%), it serves as a versatile industrial gas, with high-purity grades (≥99.999%, or 5N) essential for advanced manufacturing.

Semiconductor: used as a protective atmosphere in high-temperature processes like CVD and diffusion, as a purge gas for wafer cleaning and FOUP transfer, and as a carrier gas for uniform thin-film deposition; 5N–6N purity with oxygen below 1 ppm is required for advanced nodes.
Industrial: serves as a blanketing and displacement gas in chemical, metallurgical, and mining operations to prevent oxidation and ensure safety.
Rubber & plastics: provides inert protection in polymerisation reactors and storage tanks, preventing oxidation and side reactions in nitrile and butyl rubber production.
Laser welding: used as a shielding gas to prevent oxidation, stabilise the melt pool, and improve weld quality.
Food & pharmaceuticals: used for inert packaging, blanketing, and preservation applications.

China produces nitrogen mainly via air separation, with on-site PSA and membrane generation systems increasingly adopted by large-scale users such as wafer fabs to ensure stable purity and reduce logistics risks. The market is dominated by bulk air-separated gas, with high-purity and electronic-grade nitrogen demand growing rapidly alongside domestic semiconductor capacity expansion.

Key domestic producers:
Jiamai – PSA nitrogen generators with patented pressure-equalisation technology for electronics applications.
Zhongchuan Special Gas – electronic specialty gases including high-purity nitrogen trifluoride.
Nata Opto-electronic – high-purity electronic gases for semiconductor applications.
