As the core electronic gas for semiconductor etching, film deposition, and equipment chamber cleaning, Nitrogen Trifluoride (NF₃) is a key consumable material for chips, high-end panels, and photovoltaic manufacturing. Since 2026, the NF₃ industry has moved out of the stable and fluctuating operation range of previous years and entered a high-growth operation cycle characterized by supply contraction, high demand growth, firm prices, and capacity expansion and technological iteration. The following will analyze the core logic and future trends of the current market from four key dimensions.

The global semiconductor manufacturing industry faces a structural supply-demand imbalance. After helium and fluorine-based specialty gases, 6N–7N ultra-high-purity CO₂ for advanced chip manufacturing has become another core consumable with medium-to-long-term structural supply shortages. Multiple industry institutions forecast the global supply shortfall of this material will reach 12%–15% by 2026. Traditional gas source output has shrunk, cross-border delivery cycles have extended, and regional spot prices have kept climbing. The long-standing oligopolistic supply landscape in overseas markets has been disrupted, triggering supply chain restructuring and creating new growth opportunities for global electronic specialty gas manufacturers.

In high-end fields such as semiconductor manufacturing and electronic specialty gas applications, the safe delivery and precise control of specialty gases – silane, disilane, diborane, phosphine, arsine, hydrogen – are critical for process stability and personnel safety.
The cylinder flow restrictor, installed at the cylinder outlet, serves as the “safety gate” and “flow stabilizer” of the specialty gas system.

As the core precursor in the semiconductor chemical vapor deposition (CVD) process, tungsten hexafluoride is used to deposit a tungsten film on the wafer, creating conductive pathways within the chip. In advanced manufacturing processes below 7nm, high-bandwidth memory (HBM), and 3D NAND flash memory with 300 layers or more, there is no mature commercial alternative for tungsten hexafluoride.

A material transformation driven by “Time Scaling”

When Moore’s Law approaches the physical and economic limits, how can the performance of chips be further enhanced?

In May 2026, at the IEEE ISCAS 2026 conference, Huawei officially released the “Tau (τ) Law”, replacing the traditional “geometric shrinkage” with “Time Scaling”, and achieving continuous improvement in chip performance through original technologies such as “Logic Folding”. This fundamental shift in the technical route is profoundly reshaping the underlying logic of the semiconductor industry chain. Among them, electronic specialty gases, which are the second-largest consumable in wafer manufacturing, are undergoing a full-dimensional reshaping from the demand structure to the value logic.

Acetylene is an important chemical raw material and an environmentally friendly refrigerant (R1270). However, it is a highly flammable gas (with an explosion limit of 2.4% to 10.3%), and special attention must be paid when using and storing it.

Since early 2026, helium prices have risen significantly due to tightening supply and stable demand. In April, geopolitical tensions, supply disruptions from Qatar (impacted by production scheduling and export policies), and continued Russian export restrictions fueled market panic. Imported helium prices briefly hit highs, while tube trailer helium prices surged sharply (by more than 300%).

During the summer, the internal temperature of standard containers exposed to direct sunlight can reach 50-65°C, far exceeding normal temperatures and with significant day-night temperature differences. This period is prone to accidents, quality disputes, and cost losses in the export transportation of special gases. The following five types of gases are most severely affected and directly related to transportation safety and product delivery quality

High-value specialty gases and electronic-grade high-purity gases are characterized by high purity, high cost, and demanding operating conditions. Micro-leaks, contamination, or seal failure can not only cause costly gas loss but also lead to process risks and safety hazards.

The global helium market is facing an unprecedented supply crisis. With supply gaps widening and prices continuing to rise, helium has become a critical issue for core industries including semiconductors, healthcare, and aerospace. As an economically non-renewable rare gas that cannot be synthetically produced on an industrial scale, helium’s ultra-low boiling point, chemical inertness, and superior thermal conductivity grant it an irreplaceable strategic role across key sectors.
