1nm process step by step
According to the terms of the partnership, the details of which were not disclosed, Leti will discover new transistor structures, while Rapidus and other Japanese partners will send scientists to evaluate and test the prototypes. Rapidus has reportedly set modest targets for 1nm-class manufacturing processes and plans to improve power efficiency and performance by 10% to 20% compared to 2nm manufacturing technology. Mainstream adoption of 1nm process technology will likely occur in the 2030s, following the adoption of 2nm, 1.8nm and 1.4nm nodes later this decade.
However, Rapidus is already working with IBM and Belgium’s Imec to design a 2nm manufacturing process, begin pilot 2nm chip production in 2025, and increase high-volume production of 2nm chips in 2027. This collaboration with global partners can be seen as another vital step to revitalize Japan’s position in the semiconductor industry.
