The Tokyo conglomerate's Life Care division manufactures medical devices from contact lenses to endoscopes, while its semiconductor materials unit is the world's only producer of High-NA EUV photomask blanks — the critical chokepoint for cutting-edge chip fabrication. Both businesses demand identical precision cleanroom manufacturing, yet the supply chain risk in semiconductors remains almost entirely invisible to the medical side's stakeholders.
