Photoresist Precursors (JP) SUPPLY CHAIN TRACE

RAW MATERIALS🇯🇵 JapanChokepoint

Japan dominates the global supply of advanced photoresist chemical precursors — the polymer resins, photo-acid generators (PAGs), and quenchers that Shin-Etsu Chemical and Sumitomo Chemical formulate into EUV and ArF photoresist. Japan controls roughly 90% of the advanced photoresist market, and these upstream precursor chemicals flow almost entirely from Japanese specialty chemical manufacturers, creating a concentrated single-country dependency at the most critical patterning step in chip manufacturing.
