Large chip companies said they expected limited supply chain disruption for now from the Russia-Ukraine conflict, thanks to raw material stockpiling, but some industry sources said there could be an impact longer term.

Ukraine supplies more than 90% of US semiconductor-grade neon, critical for lasers used in chipmaking. The gas, a bi-product of Russian steel manufacturing, is purified in Ukraine, market research firm Techcet says.
