Specialty Gases

Not every material in our library is a polymer or a metal. Some of our clients' assemblies depend on ultra-high-purity process gases upstream of the component itself — most notably in semiconductor fabrication, where the chips inside consumer-electronics products are built. This entry documents the one specialty gas currently in our reference library.

Specifications below are condensed from a supplied product properties and quality inspection sheet. Supplier identity and report metadata have been intentionally omitted; this page is not an independently issued certificate of analysis. Elefant MFG's own commentary is limited to the "Elefant MFG Relevance" section.
Grade N6 · 99.9999% Purity

Semiconductor-Grade Process Gas

Purity Grade

N6 — 99.9999%

Container Valve

CGA 638 / JIS22

Shelf Life

18 months

Filling Weight

25 / 50 / 70 / 100 kg

Filling Pressure

0.09 MPa at 15°C

Container Volume

10 / 40 L

Production & Purification

Produced through a specialised gas-phase synthesis, then refined through multi-stage distillation to strip trace impurities. N6 grade holds metallic impurities to single-digit parts-per-billion levels and gas-phase impurities to sub-part-per-million levels, verified against a full certificate of analysis for every batch.

Industrial Applications

A precursor gas for chemical vapour deposition (CVD) metallisation in semiconductor fabrication — used to build the fine metal interconnect and via-fill layers inside integrated circuits.

Elefant MFG Relevance

Every product in our Consumer Electronics portfolio — wireless earphones, portable WiFi devices, food-safety detection equipment — is built around integrated circuits that depend on a CVD metallisation process using a gas at this purity level. Specifying and qualifying materials at this end of the supply chain is a narrower, more specialised part of our Material Engineering work than polymer or rare-earth selection, but it reflects the same discipline: matching a material's real specification to what the process and the end application actually require. Full technical and impurity specifications are available on request under NDA.
