Tower Semiconductor Expands Japanese Production to Secure Global Supply Chains
Tokyo, Wednesday 25 March 2026
Tower Semiconductor is drastically expanding its Japanese manufacturing capacity. This vital move secures global supply chains, signalling sustained demand for advanced manufacturing equipment to international investors.
Scaling Up: The Technical Specifications of Tower’s Expansion
On 25 March 2026, Tower Semiconductor confirmed a mutual agreement with NTCJ to scale up its 300-millimetre wafer manufacturing capacity in Japan [1]. As an independent foundry, Tower specialises in producing integrated circuits based on third-party design specifications [1]. The expansion specifically targets the 65-nanometre and 45-nanometre process geometries on 300-millimetre wafers, complementing their existing portfolio of larger geometries on 150-millimetre and 200-millimetre wafers [1]. Transitioning production to larger wafer formats—representing a diameter increase of 50 per cent compared to their 200-millimetre lines—allows for significantly higher chip yields per wafer, thereby optimising manufacturing efficiency [GPT].
Catalysing the European Semiconductor Value Chain
For European stakeholders, international foundry expansions are highly consequential. The construction and upgrading of 300-millimetre fabrication plants necessitate highly sophisticated manufacturing equipment [GPT]. Consequently, this global push directly benefits the European semiconductor value chain, particularly original equipment manufacturers such as ASML and ASM, which supply the essential lithography and deposition tools required for these precise nanoscale geometries [GPT].
Broader Corporate Resilience in the European Market
The momentum in the semiconductor sector aligns with a broader trend of corporate activity and capital restructuring observed across European markets on 25 March 2026 [2]. On the Euronext exchange, companies such as Lifecare ASA and GENERAL OCEANS ASA reported the registration of share capital increases [2]. Meanwhile, NAVAMEDIC, Lyse AS, and Eika Boligkreditt AS published their annual reports for 2025, providing transparency and reinforcing investor confidence following the previous fiscal year [2].
