Semi materials · EUV photoresist · World No.1 (22%+)

JSR Corporation

The world's No.1 in photoresist (22%+ share), making an essential material for semiconductor lithography. It supplies EUV and ArF resist to leading-edge fabs such as Samsung Foundry, TSMC and Intel, and — with five Japanese firms controlling ~90% of the global PR market — is one axis of a structural bottleneck. As EUV lithography expands, resist consumption grows, tying lithography-material demand to fab utilization.

An EUV and ArF photoresist maker (returns not tracked given its listing structure). A late-beneficiary structure as its foundry and memory customers (TSMC, Samsung above Wiwynn, Intel, Marvell) rise first and EUV materials follow. As EUV lithography expands, resist consumption grows, an essentials chokepoint forming a lithography-materials oligopoly with Tokyo Ohka and Shin-Etsu.
