Rapidus Takes Japan's 2nm Bet to Britain and Italy
· TexaHub · Semiconductors, Geopolitics & Tech, Regional Tech Ecosystems
Fresh state equity and two European memoranda signed during Prime Minister Takaichi's visits show Japan using Rapidus as an instrument of technology diplomacy before it has volume output.
Ten days, three announcements
Rapidus, the Tokyo-based company trying to bring 2nm logic manufacturing to Japan, made three announcements in ten days. On 5 June it said it had completed a 150 billion yen funding round from the Information-Technology Promotion Agency (IPA), an independent administrative agency under the Ministry of Economy, Trade and Industry [1]. On 15 June it signed a memorandum of understanding with the UK Semiconductor Centre (UKSC) [2], and on 16 June a second memorandum with Fondazione Chips-IT, Italy's centre for integrated circuit design [3].
The two European agreements were signed as part of Prime Minister Sanae Takaichi's visits to the UK on 14 June and to Italy on 15 June [2] [3]. Taken together, the sequence shows a company that is still in pilot production being used to anchor Japan's technology relationships abroad, alongside its domestic role as the country's bid to regain a position at the leading edge.
The state as shareholder
The June round follows a 100 billion yen IPA investment earlier this year, which came alongside 167.6 billion yen from 32 private companies including Canon, Development Bank of Japan, Fujitsu, NTT, SoftBank and Sony Group [1]. With the latest capital increase, Rapidus says its funding totals 424.95 billion yen in stated capital and legal capital surplus [1]. It has also received NEDO subsidies since its 2022 fiscal year for 2nm-generation integration and chiplet packaging work [1].
Rapidus says it will keep raising capital and financing "from a mix of public and private sources" to support its evolution from R&D "to full-scale 2nm logic semiconductor manufacturing by 2027" [1]. By its own figures, the IPA's two investments this year, of 100 billion and 150 billion yen, compare with 167.6 billion yen from 32 private shareholders [1]. In our reading, that balance indicates that the state, rather than industry, is still carrying most of the equity risk, which makes the government's wider diplomatic use of the company more understandable.
What the UK and Italy deals contain
Both memoranda are frameworks rather than supply or investment contracts, and the gap between the two sides' descriptions is worth noting. Rapidus says that with their signing it and the two organisations "will begin information sharing and discussions with a view to strengthening their collaborations in the future" [3]. No customer commitments, wafer volumes or monetary values were disclosed in either announcement [2] [3].
The UK partner is a national body promoting the semiconductor industry [2]. Its chief executive, Andy McLean, linked the deal to policy: "The UK Government's AI Hardware Plan recognised the importance of building trusted international manufacturing and technology partnerships that can help UK companies access the capabilities they need to innovate and grow" [2]. DIGITIMES framed the agreement as part of a push for 2nm customers and described the UKSC as a government-backed body established in 2025 [4].
The Italian partner is a Pavia-based private-law foundation established in 2023 with long-term public funding [3]. Its chief executive, Carlo Reita, said it would "develop circuits using their advanced technologies in support of our domestic ecosystem" [3]. That wording is the clearest indication in either release of a possible design-to-fabrication relationship, with Italian designers using a Rapidus process. Reita also described Rapidus as an example "on how to quickly ramp-up activities" for a young institute [3]. In January, the Japanese and Italian prime ministers had confirmed an intention to promote cooperation in fields including semiconductors [3].
The diplomatic frame
In London, the Rapidus deal sat inside a wider package. A UK-Japan Frontier Technology Partnership published on 14 June commits both countries to be "AI makers and not just AI takers" and to explore "formal pathways to interlock our AI semiconductor strengths", building on a 2023 Semiconductor Partnership [5]. A separate UK-Japan joint declaration on economic security says export control measures should be "narrowly defined, non-discriminatory, and in line with international law" and commits both sides to consult on instances of economic coercion [6]. Downing Street said the two countries were expected to agree investment creating more than £18 billion in economic gains, made up largely of more than £9 billion in infrastructure and financial services and up to £9 billion in offshore wind rather than chips [7]. The same release presented the Rapidus agreement in stronger terms than Rapidus did, saying it "creates a direct pathway for the UK semiconductor sector to manufacture cutting-edge chips used to power mobile phones, vehicles and modern devices" [7].
The context is a chip market growing at a pace that favours capacity holders. WSTS's spring forecast, as reported by DIGITIMES, projects the global semiconductor market to reach US$1.51 trillion in 2026, up 90% year on year, with memory surging 250% [8]. In our view, a boom of that kind mainly rewards suppliers that already have volume capacity, which raises the bar for a new entrant like Rapidus to win customers on anything other than geography and political trust.
What to watch
The memoranda give Rapidus potential design partners in two European ecosystems that lack leading-edge fabs, and give London and Rome a named non-US, non-Taiwanese route to advanced logic. Their value depends on whether Rapidus meets its own 2027 target for mass production, which it reiterated in both releases [2] [3]. The indicators to watch are concrete: named customers or multi-project wafer runs for UK or Italian designers, the share of private money in future funding rounds, and evidence of yields from the pilot line. Until those appear, the European agreements are best read as diplomatic commitments with an industrial option attached.
