日本代工厂，进展神速？

Group 1 - Rapidus is advancing its cutting-edge chip localization plan, aiming to start construction of its second factory in Hokkaido in FY 2027, with plans to begin mass production of 1.4 nm chips by 2029, which is among the most advanced technology tiers globally [1] - The total investment for the project is expected to reach several trillion yen, with the Japanese government providing initial funding support of several hundred billion yen, marking a key step in the revival of Japan's semiconductor industry [1] - The first factory located in Chitose aims to achieve mass production of 2 nm chips in the second half of FY 2027, despite the technology not being fully mature [1] Group 2 - The smaller the process node in nanometers, the higher the performance and energy efficiency of the chips, with the advanced 1.4 nm chips expected to serve as the "brain" for high-tech products and applications such as data centers, robotics, autonomous vehicles, and smartphones [2] - Global chip manufacturers are engaged in fierce competition over circuit width miniaturization, with TSMC planning to achieve mass production of 2 nm chips this year and launch 1.4 nm products by 2028, while Samsung aims to mass-produce 1.4 nm chips by 2027 [2] - Rapidus aims to achieve rapid scale production after the 2029 launch to keep pace with competitors, although it may face similar challenges as Samsung and Intel regarding yield improvement for advanced processes [2]
