Shin-Etsu Chemical SUPPLY CHAIN TRACE

MATERIALS🇯🇵 Japan · 4063 · TSEChokepoint

Shin-Etsu Chemical is the world's largest silicon wafer supplier with roughly 30% market share, providing the substrate on which every semiconductor chip is built. A disruption at Shin-Etsu — earthquake, production halt, or geopolitical event — would stop advanced chip production globally within weeks. The company also supplies EUV photoresist chemicals, deepening its importance to every leading-edge fab including TSMC and Samsung.
