TOKYO, Oct 7 (Reuters) – Japan’s Rapidus, with $15 billion in state backing, is tying up with chip design firms as it seeks to answer a major question hanging over the country’s tech ambitions: can it attract enough customers to its state-of-the-art chip factory?
The venture said on Monday it would partner with 17 companies including US chip design software firm Synopsys and India’s Infosys to help customers design chips.
It needs to secure customers ahead of the planned launch of 2-nanometre contract chip production in the second half of the next fiscal year, a project that Prime Minister Sanae Takaichi is counting on to rebuild Japan’s semiconductor industry.
“The biggest question for Rapidus is still who will actually fill the fab,” said Nori Chiou, investment director at White Oak Capital. Monday’s announcement was “not yet evidence of commercial traction,” he said, but showed incremental progress.
It also faces technological and competitive hurdles as it looks to make 2-nm chips, which offer faster, more energy-efficient performance than earlier generation chips, at its fabrication plant.
Failure of the project would be a major setback for Japan’s industrial strategy and could reverberate across the country’s chip sector, as it seeks to strengthen supply chain resilience amid rising regional tensions and concerns over a possible Chinese move against Taiwan.
HEAVYWEIGHT COMPETITION
The unprecedented AI investment boom has fuelled demand for semiconductors and computing infrastructure, a trend Rapidus hopes to capitalise on.
It is up against Taiwan’s TSMC, which spent decades refining its processes and dominates leading-edge chipmaking, South Korea’s Samsung Electronics which began producing 2-nm chips last year, and Intel.
TSMC “will continue to dominate the majority of the market. But there are plenty of customers in the remaining 20% who cannot get capacity from TSMC because they are low on its priority list or their orders are small,” said Akira Minamikawa, an analyst at Omdia.
Rapidus CEO Atsuyoshi Koike expressed confidence there is enough market demand to support an additional leading-edge manufacturer.
“One or two companies are nowhere near enough,” Koike told Reuters.
Some potential customers remain cautious.
“We’re already having TSMC make our chips, so we can’t switch everything to Rapidus. If it didn’t work out, we couldn’t go back to TSMC, so we have to be cautious,” said one executive who declined to be identified because the deliberations are private.
Customers may use Rapidus to diversify supply chains, while the presence of a leading-edge manufacturer could also benefit Japan’s materials and equipment makers, Minamikawa said.
Japan’s global semiconductor market share has fallen from about 50% in the 1980s to less than 10% today. Chipmakers operating in Japan include memory producer Kioxia and TSMC, which has partnered with Sony.
Other government-backed initiatives include Noetra, which is developing a foundational model for physical AI and robotics.
TECHNOLOGICAL HURDLES REMAIN
Preparations for mass production are progressing on schedule and the environment is better than envisioned when Rapidus was founded in 2022, CEO Koike said.
Yet significant technological hurdles remain. Rapidus is working with IBM and has started pilot operations, but experts say commercial success remains far from guaranteed.
“Running a chip fab around the clock, maintaining stable, consistent yields and continuing production in a way that makes the business viable is extremely difficult,” said Kazuyoshi Saito, an analyst at IwaiCosmo Securities.
“Even Samsung … has struggled.”
Beyond proving its technology, Rapidus faces the longer-term challenge of building a profitable business. The company is targeting an initial public offering by around the financial year ending March 2032.
“Its success or failure won’t be known for 10 years and no one will be able to take responsibility,” said a government official, pointing to the government-backed Cool Japan Fund, which booked investment losses.
Still, Rapidus’ backers have ambitious plans. A listing and manufacturing operations in the United States are possibilities, said Daishiro Yamagiwa, a lawmaker who heads the ruling Liberal Democratic Party’s parliamentary group on chip strategy.
