Japanese Chipmaker Rapidus Secures Major Funding
Japanese semiconductor company Rapidus has secured 267.6 billion yen in a new funding round from the Japanese government and private sector partners. The company stated the investment will allow it to move from its current R&D phase to mass production of 2-nanometer logic semiconductors by 2027.
This latest funding round brings the total public and private investment in Rapidus to nearly 275 billion yen, with the Japanese government contributing 100 billion yen and 32 private companies adding 167.6 billion yen. Key private sector backers include major players like Toyota, Sony, SoftBank, Canon, and NEC, signaling a broad national effort to re-establish Japan's leadership in advanced semiconductor manufacturing. The government's investment secures it a "golden share," allowing it to veto major company decisions and increase its stake if the company faces financial difficulties, underscoring the project's national strategic importance. This initiative is a direct attempt to leapfrog current domestic capabilities, which lag at the 40nm node, and compete at the cutting edge. Rapidus's technical foundation is a strategic partnership with IBM, which is transferring its 2-nanometer process technology, including Gate-All-Around (GAA) transistor architecture. More than 150 Rapidus engineers have been working alongside IBM researchers at the Albany NanoTech Complex in New York to master the manufacturing process. This collaboration recently expanded to include advanced chiplet packaging technologies. Construction of the "Innovative Integration for Manufacturing" (IIM) fab in Chitose, Hokkaido, is proceeding rapidly. After breaking ground in September 2023, the facility received its first advanced EUV lithography machine from ASML in December 2024. Rapidus successfully started prototyping 2nm GAA transistors by July 2025 and aims to have its pilot line operational in April 2025. The company's strategy is not to compete with giants like TSMC on volume for standardized chips. Instead, Rapidus aims to differentiate by offering high-performance, specialized semiconductors with a significantly shorter production cycle time, targeting the evolving needs of the AI and high-performance computing markets. To engage with the crucial U.S. market, Rapidus established a Silicon Valley subsidiary, Rapidus Design Solutions, in April 2024. The subsidiary is led by industry veteran Henri Richard and is tasked with serving fabless semiconductor companies and technology partners in the Americas, aiming to accelerate their time-to-market. Despite the aggressive timeline and substantial backing, Rapidus faces significant hurdles. These include the immense technical challenge of jumping directly to 2nm production, the need to secure a customer base for a new and unproven foundry, and its heavy reliance on continued government funding to compete with established players.
