Fujitsu to Develop Advanced 1.4nm AI Chip Manufactured by Japanese Firm Rapidus

• March 31, 2026

Fujitsu has announced plans to develop a new 1.4-nanometer (nm) chip specifically tailored for artificial intelligence (AI) infrastructure. The production of this chip will be handled by Rapidus, a Japanese semiconductor manufacturing company backed by several domestic corporations.

Collaboration Between Fujitsu and Rapidus to Advance AI Chip Production

Rapidus, which operates as a contract chip manufacturer, is seeking partnerships with multiple Japanese firms that have invested in its development. Among its efforts to secure clients within Japan’s technology ecosystem, Rapidus has already garnered interest from Canon regarding a separate 2nm chip manufacturing project. Building on this momentum, the company will now also produce Fujitsu’s forthcoming 1.4nm AI-focused semiconductor.

This collaboration marks a significant step forward for Japan’s ambitions in the semiconductor industry, particularly in the realm of advanced AI hardware. The move to develop and manufacture chips at a scale smaller than 2nm reflects the ongoing push for more efficient and powerful processors that can support increasingly complex AI workloads.

Details about Fujitsu’s specific chip design, as well as the production capacity and commercial availability timelines, have not yet been disclosed. Nonetheless, the partnership highlights the growing trend among Japanese technology firms to enhance domestic semiconductor manufacturing capabilities amidst a competitive global market.

By leveraging Rapidus’ manufacturing expertise and Fujitsu’s technological development, the initiative aims to contribute to innovation in AI infrastructure. Such chips are expected to play a crucial role in accelerating AI applications across various sectors, including computing, data centers, and possibly edge computing environments where performance and energy efficiency are paramount.

The Japanese government’s support for homegrown semiconductor advancements and the establishment of domestic foundries like Rapidus demonstrate a strategic effort to reduce reliance on international suppliers. This cooperation with Fujitsu aligns with broader industry trends emphasizing supply chain resilience and advanced chip development within the country.

As the race for leading-edge semiconductor technology intensifies worldwide, Fujitsu and Rapidus’ partnership on the 1.4nm AI chip will be closely watched by industry observers interested in the evolution of AI hardware capabilities and Japan’s role in the global tech landscape.
