Japan's JSR, the world's No. 2 supplier of photoresist with a 19% global market share by sales last year, has announced plans to build its first production facility in Taiwan to supply semiconductor materials to Taiwan Semiconductor Manufacturing Co. (TSMC) [1]. This strategic move aims to reinforce JSR's position in the global supply chain, ensuring a stable supply of photoresist to TSMC, the world's leading chip foundry, and to maintain its competitive edge as Chinese companies increasingly target the semiconductor materials market [1].

Photoresist is a critical material used in the photolithography process of semiconductor manufacturing, and demand for it is expected to grow as chipmakers ramp up production for advanced technologies, including next-generation chips based on 2-nm technology [1]. The article notes that Japanese material suppliers, including JSR, are actively seeking to tap into this demand, particularly as advancements in artificial intelligence and other emerging technologies drive further growth in the sector [1].

While the article does not disclose specific financial details regarding the investment or the production capacity of the new plant, it highlights the ongoing battle for market share among key players in the semiconductor ecosystem, especially in the context of geopolitical tensions and concerns over technology leaks [1]. Industry analysts cited in the article observe that Japanese companies are expanding their chip material operations to secure their international market presence amid intensifying competition [1].

CONCLUSION

JSR's decision to establish a photoresist plant in Taiwan marks a significant step in strengthening its partnership with TSMC and securing its position in the global semiconductor supply chain. The move reflects broader industry trends as Japanese material suppliers respond to rising demand and increased competition from China.
