Abstract
Ukraine, Neon, and Semiconductors (USITC Executive Briefing). Fetched by the auto-model research pass; the figures below are cited from this source in the model's flow, idiot-index, energetic-index, and market tabs.
Key facts
- Ukraine supplied ~50% of world neon; nearly all US ultra-high-purity semiconductor-grade neon imports
- Neon is ~96-97.5% of the excimer gas mixture used in DUV photolithography lasers
- Neon byproduct of Soviet-legacy steel industry
Reviewer note
