Producer
DuPont Electronics (DuPont de Nemours)
DuPont Electronics & Industrial is the semiconductor materials division of DuPont de Nemours, Inc. (NYSE: DD; Wilmington, Delaware). DuPont's EUV photoresist operation is headquartered at Marlborough, Massachusetts, and represents approximately 8% of the global EUV-specific photoresist market — the only significant non-Japanese EUV resist supplier globally. DuPont's photoresist heritage traces to its acquisition of Shipley Company (2000) and Rohm and Haas Electronic Materials (2009), which brought chemically amplified resist chemistry expertise. DuPont's Marlborough MA facility is the primary U.S. foothold in a market dominated ~92% by Japanese companies. DuPont EUV resists are qualified at Intel's advanced nodes and serve as a diversification option for fabs seeking to reduce Japan supply dependence.

DuPont Electronics Marlborough MA EUV Resist Facility →
USMassachusetts · manufacturing
DuPont Electronics' Marlborough, Massachusetts facility is the primary U.S. EUV photoresist manufacturing site — one of the very few EUV resist manufacturing locations outside Japan. The facility traces its origins to Shipley Company (acquired by Rohm and Haas 1999; acquired by DuPont 2009) which was a photoresist pioneer in the Boston area. DuPont Marlborough produces both ArF and EUV photoresist variants qualified at Intel advanced nodes and available to fabs seeking to diversify away from Japanese supply.

DuPont Electronics Sasakami Plant (Niigata, Japan) →
JPNiigata Prefecture · manufacturing
DuPont Electronics primary photoresist manufacturing facility in Agano-shi (Sasakami), Niigata, Japan. Major expansion completed October 2024 — nearly doubled capacity — with new East Star Building featuring ISO Class 10-1000 cleanrooms and advanced automation. Produces g-line through EUV photoresists. DuPont is a U.S. company, but its photoresist production is concentrated in Japan.

Did you know2024
DuPont Electronics — one of the most prominent U.S. chemical companies, presenting itself as an American alternative to Japanese photoresist suppliers — manufactures its photoresist at a single primary facility in Sasakami, Niigata, Japan (not in the United States). DuPont's October 2024 capacity expansion at Sasakami (nearly doubling output with ISO Class 10-1000 cleanrooms) further consolidated its production in Japan. CHIPS Act policy rhetoric about reducing photoresist dependence on Japan does not apply to DuPont's supply chain: its photoresist manufacturing is subject to the same Japan earthquake risk, Japan export control risk, and Japan regulatory environment as JSR, TOK, and Shin-Etsu.
DuPont ↗Origin2023
DuPont's semiconductor photoresist business was assembled through two landmark acquisitions: Shipley Company (Marlborough, Massachusetts, 2000) and Rohm and Haas Electronic Materials (2009). Shipley was founded in 1953 as a printed circuit board chemistry company and was the inventor of chemically amplified photoresist (CAR) in the 1980s -- the technology that enabled the scale-down from micron to nanometer chip features. Rohm and Haas Electronic Materials brought CMP slurry and specialty chemical manufacturing. The combined DuPont Electronics is technically the most significant non-Japanese semiconductor materials supplier -- but its EUV photoresist production is at Sasakami, Niigata, Japan, an October 2024 expansion that doubled capacity while concentrating production further in Japan. DuPont presents as an 'American alternative' to Japanese photoresist suppliers in CHIPS Act policy discussions, but its photoresist manufacturing geography means it shares the earthquake, regulatory, and export control risk of its Japanese competitors. The policy narrative and the operational reality diverge significantly.
