Rapidus Signs 17 Design Partners to Win 2nm AI Chip Customers
3 min readJapan’s state-backed chipmaker Rapidus has signed up 17 chip design partners, including US design software leaders Synopsys and Cadence, to help it find customers for its 2nm production line. The move, reported by Nikkei Asia on October 7, is the clearest sign yet that the roughly $15 billion foundry project is shifting from building a factory to filling it.
A national bet on leading-edge chips
Rapidus was founded in 2022 with backing from the Japanese government and a group of domestic companies that includes Toyota, Sony, NTT and SoftBank. Its goal is ambitious: restore Japan to the front rank of semiconductor manufacturing by jumping straight to 2nm, the most advanced process node in production anywhere, using gate-all-around transistor technology licensed from IBM.
The company built its first fab in Chitose, on the northern island of Hokkaido, and began running a prototype line there in 2025. Mass production of 2nm chips is scheduled to begin in the second half of the next fiscal year. The chips Rapidus wants to make are exactly the kind that power AI accelerators and data center processors, a market dominated today by Taiwan’s TSMC.
What the partners will do
According to Nikkei Asia, the 17 firms will work with Rapidus to design chips for clients and steer those designs toward the Hokkaido fab. Alongside Synopsys and Cadence, the two companies whose tools are used to lay out nearly every advanced chip in the world, the group includes Toshiba Information Systems, Dai Nippon Printing, Toppan and India’s Infosys.
The logic is simple. A new foundry cannot win orders unless customers can design for its process, and most would-be customers lack the in-house expertise to do so on an unproven node. By recruiting a ready-made ecosystem of design houses, Rapidus lowers the barrier for AI startups, automakers and electronics firms that want an alternative to TSMC but have never taped out a 2nm chip.
Why it matters
The AI boom has turned leading-edge foundry capacity into a strategic resource, and almost all of it sits in Taiwan. Governments from Washington to Tokyo have poured subsidies into alternatives, but subsidies do not create customers. Rapidus’s prospects now depend on whether this design network can convert interest into committed wafer orders before the money runs out.
The partnership also shows how global the effort has become. US design tool vendors and an Indian IT services giant are helping a Japanese foundry chase business that would otherwise go to Taiwan. For the AI industry, a credible second source for 2nm silicon would ease one of its biggest supply chain risks.
Watch for the first named customers, and for whether Rapidus can hold its production timeline as the Chitose line scales up.
