Introduction
Neon gas is one of the most important rare gases used in semiconductor lithography, excimer laser systems, scientific research, aerospace technology, and advanced optical manufacturing.
The global neon gas supply chain is closely connected to:
- Steel production
- Air separation units (ASU)
- Rare gas purification technology
- Semiconductor manufacturing
Crude neon is mainly extracted as a byproduct during large-scale air separation processes in steel and industrial gas facilities. After extraction, crude neon must undergo advanced purification processes to produce semiconductor-grade high purity neon gas.
High purity neon gas is commonly classified as:
- 5N Neon Gas (99.999%)
- 6N Neon Gas (99.9999%)
Major neon gas producing regions include:
- China
- Ukraine
- Russia
- United States
- European Union
The semiconductor industry is the largest high-end consumer of neon gas because excimer laser systems used in lithography require stable and ultra-high purity neon gas.
As global semiconductor demand continues to increase, stable neon gas supply chains have become strategically important for chip manufacturing and high-tech industries worldwide.
