Ukraine is a major producer of neon gas, which is critical for lasers used in chipmaking, with one company, Iceblick, supplying around 65% of the world's production. The country's dominance in neon production is due to its existing infrastructure and expertise, which was initially developed as part of a Soviet-era laser defense project. The concentration of neon production in Ukraine has raised concerns about the fragility of the global semiconductor industry. The industry's reliance on Ukraine and other countries for critical components has sparked discussions about supply chain risks and geopolitical tensions.
