Japanese Minister of Economy, Trade and Industry Yasutoshi Nishimura pledged the government would hike its financial support for chipmaker Rapidus Corp as it works to develop cutting-edge semiconductors, saying that domestic production of such components is essential for the country to excel in artificial intelligence (AI) and autonomous driving.
“I have high hopes that Rapidus can mass produce 2-nanometer chips and beyond in Japan, and the government is ready to continue and beef up financial support to the company, as it will need to spend trillions of yen to make that happen,” Nishimura said in an interview.
Tetsuro Higashi, former chairman of Tokyo Electron Ltd, and Atsuyoshi Koike, former president of Western Digital Corp, established Tokyo-based Rapidus last year with the goal of making the cutting-edge, 2-nanometer chips in Japan by 2025. The duo drew investment from companies including Toyota Motor Corp, Sony Group Corp and Nippon Telegraph & Telephone Corp.

The project is seen as a quasi-public-sector effort, with Rapidus becoming a potential national champion as the nation tries to develop a strong local chip sector. The government contributed ¥70 billion (US$532 million) in financial aid for its launch.
Japan’s efforts come as countries around the world are seeking to build their own semiconductor capabilities, a strategic priority after the COVID-19 pandemic shut down global commerce and as the US-China conflict threatens the old standards of free trade. The US, China, South Korea and Europe are all pouring billions of US dollars into the sector to secure supplies.
Japan was once a chip superpower with a dominant share of the memorychip market, but it ceded that position in part because of its own clash with the US over what constituted fair industrial policy.
Japanese lawmaker Akira Amari, a former minister of economy, trade and industry, told Bloomberg in January that Japan lost its edge because individual companies made development choices independently and the government failed to work well with the US administration of the time.
Some analysts are skeptical that Rapidus can achieve 2-nanometer production in such a short period of time, considering it is more advanced than what leaders such as Taiwan Semiconductor Manufacturing Co (台積電) and Samsung Electronics Co offer now.
They also question whether Japan will have many buyers for such chips; the nation’s biggest industries, including automaking, use mostly older, less advanced chips.
“Unfortunately, Japan isn’t a home of companies like Apple Inc that would use a lot of newest chips today,” Nishimura said in the interview. “But cutting-edge chips will be a key for a wide range of industries within the next five to 10 years, such as autonomous driving, ChatGPT-like AI services, as well as quantum computing.”
He said the government would monitor Rapidus’ progress with a plan to “provide continued, bigger support” if necessary.
Rapidus has international support: It is working with IBM Corp of the US and Interuniversity Microelectronics Centre of Belgium on its production plans.
“I want to see Japan once again make top-notch chips domestically,” Nishimura said. “There are already a lot of Japanese firms that have long been providing the world’s top-class chip production machinery and materials.”
Taiwan’s foreign exchange reserves fell below the US$600 billion mark at the end of last month, with the central bank reporting a total of US$596.89 billion — a decline of US$8.6 billion from February — ending a three-month streak of increases. The central bank attributed the drop to a combination of factors such as outflows by foreign institutional investors, currency fluctuations and its own market interventions. “The large-scale outflows disrupted the balance of supply and demand in the foreign exchange market, prompting the central bank to intervene repeatedly by selling US dollars to stabilize the local currency,” Department of Foreign
Intel Corp is joining Elon Musk’s long-shot effort to develop semiconductors for Tesla Inc, Space Exploration Technologies Corp and xAI, marking a surprising twist in the chipmaker’s comeback bid. Intel would help the Terafab project “refactor” the technology in a chip factory, the company said on Tuesday in a post on X, Musk’s social media platform. That is a stage in the development process that typically helps make chips more powerful or reliable. The chipmaker’s shares jumped 4.2 percent to US$52.91 in New York trading on Tuesday. The Terafab project is a grand plan by Musk to eventually manufacture his own chips for
ENERGY ISSUES: The TSIA urged the government to increase natural gas and helium reserves to reduce the impact of the Middle East war on semiconductor supply stability Chip testing and packaging service provider ASE Technology Holding Co (日月光投控) yesterday said it planned to invest more than NT$100 billion (US$3.15 billion) in building a new advanced chip testing facility in Kaohsiung to keep up with customer demand driven by the artificial intelligence (AI) boom. That would be included in the company’s capital expenditure budget next year, ASE said. There is also room to raise this year’s capital spending budget from a record-high US$7 billion estimated three months ago, it added. ASE would have six factories under construction this year, another record-breaking number, ASE chief operating officer Tien Wu
Taiwan Power Co (Taipower, 台電) yesterday said it plans to resume operations at two coal-fired power generators for three months to boost security of electricity supply as liquefied natural gas (LNG) supply risks are running high due to the Middle East conflict. The two coal-fired power generators are at Mailiao Power Plant in Yunlin County’s Mailiao Township (麥寮). The plant, operated by Formosa Plastics Group (台塑集團), supplied electricity to Taipower’s power grid until the end of last year. Taipower’s decision came about one month after Minister of Economic Affairs Kung Ming-hsin (龔明鑫) on March 10 said that the nation had no imminent
