Nitrogen Trifluoride (NF₃)
Product Overview
Nitrogen trifluoride (NF₃)is tHe preferred chamber cleaning gas for chemical vapor deposition (CVD) tools and an effective plasma etching gas for dielectric materials. Compared to alternative perfluorocarbons,NF₃ offers significantly higher etch rates, lower global warming potential (GWP 16,600 vs. CF₄ 6,500), and reduced residue formation, making it the industry standard for advanced semiconductor manufacturing .
According to TECHCET data, the global electronic specialty gas market reached $4.64 billion in 2025, with NF₃ representing one of the largest volume segments. The Asia-Pacific region accounts for approximately 74.4% of global semiconductor gas consumption, with China, Taiwan, and Korea representing major demand centers .

Capacity Expansion Developments
On March 2, 2026, Hubei Heyuan Gas announced a ¥684 million investment to expand its electronic grade NF₃ capacity by 4,500 tons/year at its Yichang facility, with Phase I (3,000 tons/year) under construction and projected investment profit rate of 24.50% with a payback period of 5.27 years .
This expansion reflects the broader industry trend of increasing NF₃ capacity to meet growing semiconductor demand. According to Hua Tai Securities research, SK Hynix environmental impact assessment documents indicate that transition from 54nm to 10nm processes significantly increases NF₃ consumption per wafer .
Market Dynamics
According to Huao Industry Research Institute data, China's integrated circuit sector accounts for 42% of total electronic specialty gas demand, while the display panel sector accounts for 37%. China's electronic gas market reached 28.08 billion RMB in 2024, with a compound annual growth rate of 14.4% from 2017-2024 .
NF₃ consumption is directly correlated with:
-
Wafer start volumes across all technology nodes
-
Number of deposition and etch cycles (increases with 3D architectures)
-
Display panel production capacity expansion
-
Photovoltaic manufacturing growth
