Producer
Shin-Etsu Chemical
Shin-Etsu Chemical Co., Ltd. (Tokyo; TSE: 4063; ~¥2.3 trillion revenue) is Japan's second-largest EUV photoresist supplier, holding approximately 20-25% of the EUV photoresist market through its SEPR (Shin-Etsu Polymer Resist) product line. Primary EUV resist production at Niigata and Gunma facilities in Japan. The same parent company is the world's largest polyvinyl chloride (PVC) producer, the world's largest silicon wafer producer (through Shin-Etsu Silicones/SEH), and a major hydroxypropyl methylcellulose (HPMC) pharmaceutical excipient manufacturer. Shin-Etsu's photoresist was among the materials covered by Japan's July 2019 export controls targeting South Korea, as fluorinated polyimide — a resist ancillary material — was one of the three restricted chemicals.

Shin-Etsu Chemical Niigata Plant (SEPR Photoresist) →
JPNiigata Prefecture · manufacturing
Shin-Etsu Chemical's Niigata plant produces SEPR (Shin-Etsu Polymer Resist) EUV photoresist, alongside specialty chemical products. Niigata Prefecture sits on Japan's west coast facing the Sea of Japan — a seismically active region (Niigata-Chuetsu earthquake 2004, M6.8; Niigata-Chuetsu-oki 2007, M6.8 damaged nearby Kashiwazaki-Kariwa nuclear plant). The Shin-Etsu Niigata complex concentrates multiple specialty chemical production lines in a seismic zone. Source: https://www.shinetsu.co.jp/en/

Did you know2023
Shin-Etsu Chemical is simultaneously the world's #1 silicon wafer manufacturer (through Shin-Etsu Handotai / SEH), the world's #1 polyvinyl chloride (PVC) producer, a major EUV photoresist supplier (~23% EUV market), and the world's largest manufacturer of hydroxypropyl methylcellulose (HPMC) — the excipient used in the vast majority of pharmaceutical capsule shells globally. The same Tokyo parent company supplies: the silicon wafer a chip is patterned on, the photoresist used to pattern it, PVC piping used in the water systems of the fabs that make it, and the capsule shell of the medication taken by the fab workers. This cross-sector dependency concentration is extraordinary: a single major disruption at Shin-Etsu would simultaneously impact semiconductor fabrication, pharmaceutical manufacturing, and construction materials supply chains.
