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.
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.
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.
