Japan’s Rapidus Corp has prototyped an advanced chip, an early step in the government-backed start-up’s attempt to leapfrog years of innovation with the help of billions of dollars of public funding.
The firm last week printed circuitry on wafers using 2-nanometer gate-all-around process technology, Rapidus president Atsuyoshi Koike told reporters yesterday.

Rapidus, which in April began developing wafers using extreme ultraviolet (EUV) lithography equipment from ASML Holding NV, aims to be ready to help customers with their chips by March next year, Koike said.
The company, which hopes to mass produce cutting-edge semiconductors by 2027, remains far behind industry leader Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), which plans to begin volume production of its 2-nanometer process later this year.
“I don’t think anyone else has been able to succeed at EUV lithography in just three months,” Koike said at a news conference in Chitose on Japan’s northern island of Hokkaido and the site of Rapidus’ factory. “To get to this stage, none of us slept.”
Japan has earmarked more than ￥1.72 trillion (US$11.6 billion) for Rapidus, part of a moonshot bid to manufacture cutting-edge chips at home. The overwhelming majority of the world’s advanced artificial intelligence (AI) chips are manufactured by TSMC, sparking fears about reliance on a nation that China claims as its own.
Critics point to how past Japanese government efforts to help the private sector failed to revive the nation’s leadership — whether in displays, solar panels or memory chips — but uncertainty about US President Donald Trump’s willingness to defend Taiwan in the event of an attack is spurring Japan’s efforts to build its own foundry.
Rapidus has also received funding from local industry leaders such as Toyota Motor Corp and Sony Group Corp.
“The world is astonished by how far we’ve come. Japan’s now taking on cutting-edge technology after lagging behind by more than a decade,” Rapidus chairman Tetsuro Higashi said.
Japanese officials have acknowledged the risks associated with the project.
Tokyo is studying plans to get golden shares with veto powers in exchange for some of the public money it’s promised. The government also is preparing to guarantee Rapidus’ debt, a move that the country’s lenders say is essential for them to lend to a startup that requires billions of dollars in equipment.
Rapidus is developing advanced chipmaking processes with IBM Corp, and has partnerships with the likes of Belgian research hub Interuniversity Microelectronics Center, the University of Tokyo and Japan’s Riken research institute.
SECOND-RATE: Models distilled from US products do not perform the same as the original and undo measures that ensure the systems are neutral, the US’ cable said The US Department of State has ordered a global push to bring attention to what it said are widespread efforts by Chinese companies, including artificial intelligence (AI) start-up DeepSeek (深度求索), to steal intellectual property from US AI labs, according to a diplomatic cable. The cable, dated Friday and sent to diplomatic and consular posts around the world, instructs diplomatic staff to speak to their foreign counterparts about “concerns over adversaries’ extraction and distillation of US AI models.” Distillation is the process of training smaller AI models using output from larger, more expensive ones to lower the costs of training a powerful new
Shares of Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) have repeatedly hit new highs, but an equity analyst said the stock’s valuation remains within a reasonable range and any pullback would likely be technical. The contract chipmaker’s historical price-to-earnings (P/E) ratio has ranged between 20 and 30, Cathay Futures Consultant Co (國泰證期) analyst Tsai Ming-han (蔡明翰) told Central News Agency. With market consensus projecting that TSMC would post earnings per share of about NT$100 (US$3.17) this year, supported by strong global demand for artificial intelligence (AI) applications, and the stock currently trading at a P/E ratio of below 25, Tsai said the valuation
The artificial intelligence (AI) boom has triggered a seismic reshuffling of global equity markets, with Taiwan and South Korea muscling past European nations one by one. With its stock market now valued at nearly US$4.3 trillion, Taiwan surpassed the UK, Europe’s biggest market, earlier this month, data compiled by Bloomberg showed. South Korea is about US$140 billion away from doing the same. The tech-heavy Asian markets have shot past Germany and France in the past seven months. The shift is largely down to massive gains in shares of three companies that provide essential hardware for AI: Taiwan Semiconductor Manufacturing Co (TSMC, 台積電),
The US Department of Commerce last week ordered multiple chip equipment companies to halt shipments of certain tools to China’s second-largest chipmaker, Hua Hong Semiconductor Ltd (華虹半導體), its latest action to slow the country’s development of advanced chips, two people familiar with the matter said. The department sent letters to at least a handful of companies informing them of restrictions on tools and other materials destined for two Hua Hong facilities US officials believe make China’s most sophisticated chips, the people said. Top US chip equipment companies Lam Research Corp, Applied Materials Inc and KLA Corp, each of which has significant
