Japan approved ¥631.5 billion ($4 billion) in additional subsidies for Rapidus Corp., bringing total government support for the chipmaker to $16 billion as the country attempts to re-enter advanced semiconductor manufacturing.
The Japanese government authorized the new funding to accelerate Rapidus's timeline for producing cutting-edge AI chips. The company aims to manufacture 2-nanometer semiconductors, placing it in direct competition with industry leaders Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung.
Rapidus was founded in 2022 with backing from Toyota, Sony, NTT, and other major Japanese corporations. The company plans to begin mass production by 2027, an ambitious target given Japan's decades-long absence from the leading edge of chip manufacturing.
The project faces significant hurdles. Japan once dominated the global semiconductor market in the 1980s but lost ground to competitors in Taiwan, South Korea, and the United States. Rapidus must now compress years of technological development into a condensed timeframe while competing against established players with deeper expertise and larger production scales.
The $16 billion in total government subsidies represents one of Japan's largest industrial policy bets. The funding will support construction of Rapidus's fabrication facility in Hokkaido and development of advanced manufacturing processes in partnership with IBM and Belgian research organization imec.
Global demand for AI chips has surged following the success of large language models and generative AI applications. The United States, European Union, and other governments have launched similar initiatives to secure domestic chip production capabilities, viewing semiconductor self-sufficiency as a matter of economic and national security.
Rapidus has not yet demonstrated production of chips at the 2-nanometer node. The company's success depends on solving complex technical challenges, recruiting specialized talent, and establishing reliable supply chains for advanced manufacturing equipment and materials.
