Shin-Etsu Chemical

World's largest silicon wafer and photoresist maker

Shin-Etsu Chemical is the largest global supplier of silicon wafers and also a top-tier producer of photoresists (including EUV resists) and photomask blanks, giving it an unusually broad grip on semiconductor materials. It is the #1 or #2 vendor in multiple materials categories that TSMC, Samsung and Intel depend on. Its dual dominance in both wafers and resists makes it one of the most systemically important materials companies in the AI hardware supply chain.
