Semiconductor Nitrogen (N2 6N)

Description

1. Product Overview
Semiconductor Nitrogen (N2 6N) is an ultra-high-purity, non-reactive carrier and purge gas containing 99.9999% nitrogen by volume, with total impurities strictly below 1 ppm. It is primarily used in critical semiconductor fabrication processes including chemical vapor deposition (CVD), furnace purging, and photoresist drying. The key value proposition is defect reduction: by eliminating oxygen and moisture contamination at the parts-per-million level, this gas directly increases wafer yield and device reliability. Strategically, it is indispensable for fabs transitioning to 5nm, 3nm, and below, where atomic-level cleanliness dictates commercial viability.

2. Key Specifications & Technical Characteristics

• Chemical Composition: N2 ≥ 99.9999%; total impurities (O2, H2O, CO, CO2, THC) ≤ 1.0 ppmv; individual impurity (O2/H2O) ≤ 0.2 ppmv

• Purity Grade: 6N (99.9999%) – Semiconductor Grade; optionally certifiable to 7N (99.99999%) upon request

• Physical Characteristics: Colorless, odorless, compressed non-flammable gas; molecular weight 28.01 g/mol; dew point ≤ –85°C (equivalent to ≤ 2 ppb H2O)

• Packaging Options: Stainless steel cylinder (44L/110L) with CGA/DISS 718 valve; ISO tube trailer (12,000–15,000 L water capacity); bulk liquid tanker delivery (5,000–20,000 L)

• Shelf Life: 36 months from date of analysis in sealed, certified cylinders (provided valve integrity maintained)

3. Core Industrial Applications

• Primary Industries: Advanced logic and memory semiconductor fabs (foundries, IDMs), MEMS, photonics, and compound semiconductor (GaN, SiC) manufacturing

• Specific Use Cases:

  • Furnace purging – reduces native oxide growth during diffusion and annealing

  • EUV lithography purge – eliminates carbon deposition on mirrors

  • Transfer lines for liquid precursors – prevents hydrolysis and particle nucleation

• Why It Performs Better: Our sub-0.2 ppm O₂ and H₂O exceed SEMI C3.6 standards, directly translating to 0.5–1.5% higher device yield than standard 5N (99.999%) nitrogen. Lower particle counts (< 0.1 particles/ft³ for ≥ 0.1 µm) reduce tool downtime for chamber cleaning by 20%.

4. Competitive Advantages

• Quality Consistency: Each batch analyzed via atmospheric pressure ionization mass spectrometry (APIMS) – certificate of analysis (CoA) with traceable NIST standards provided per shipment; lot-to-lot variation < 5%.

• Supply Reliability: Dual-sourced from air separation units (ASU) with redundant liquefaction; on-site storage buffer tanks and 24/7 telemetry monitoring ensure zero unplanned outages.

• Logistics Capability: Global ISO 9001:2024 certified distribution network – delivery within 48 hrs for 80% of Tier-1 fab clusters (US, EU, Korea, Japan, China, Taiwan).

• Price Competitiveness: Long-term take-or-pay contracts at 12–18% below spot market premium for 6N grade; volume-tiered discounts above 20,000 m³/month.

• Sustainability: Carbon-neutral delivered option via verified renewable energy credits applied to liquefaction; zero-to-landfill cylinder management program.

• Technical Support: Dedicated gas abatement engineering team; on-site purity auditing; 24/7 spec sheet and MSDS access via supplier portal.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 1 x 44L cylinder (equivalent to 9.5 m³ of gaseous N2 at STP) for initial qualification; for production contracts, MOQ is 20 MT liquid equivalent

• Bulk Loading Capacity:

  • 20 MT per ISO tube trailer (water volume approx. 15,000 L liquid N2 → ~12,000 m³ gas)

  • 20 MT per bulk cryogenic liquid tanker (standard road tanker capacity for direct fab delivery)

  • Containerized shipments: 20 MT fits into 1 x 20-ft ISO cryo-container; 40-ft container holds max 20 MT due to weight limits (tare + product ≤ 30,000 kg
