Japan plans [more than 3 trillion yen in subsidies and equity](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) for a four-year-old startup that wants to build chips only TSMC, Samsung and Intel make today. On November 10, 2026, reports said that startup, Rapidus, [hasn't yet produced working SRAM cells](https://www.trendforce.com/news/2026/11/10/news-rapidus-reportedly-months-behind-on-2nm-sram-development-march-2028-mass-production-target-at-risk/?ref=insidedeeptech.com), a milestone that was due by the summer.

A day later, Jiji Press reported that Rapidus is [weighing a one-year delay](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) of 2nm mass production, from the second half of fiscal 2027 to fiscal 2028\. Rapidus says its target hasn't changed. That gap between the official plan and the reporting is the Rapidus story right now.

This full guide covers what Rapidus is, the IBM 2nm technology it licensed, the IIM-1 fab in Hokkaido, its single-wafer manufacturing model, the funding, the customers it doesn't have yet, the delay risk and the honest limits. Last updated: November 15, 2026.

## Key Takeaways

- Rapidus targets 2nm GAA mass production in [the second half of fiscal 2027](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-opens-analysis-center-and-rapidus-chiplet-solutions/?ref=insidedeeptech.com) at IIM-1 in Chitose, Hokkaido.
- Reports say SRAM is behind and a [one-year slip to fiscal 2028](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) is under discussion; Rapidus denies a change.
- Government support could reach [3.2 trillion yen by 2029](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com), including 650 billion yen of planned equity.
- Rapidus's technology comes from [IBM's 2nm node](https://www.rapidus.inc/en/news%5Ftopics/information/ibm-and-rapidus-form-strategic-partnership-to-build-advanced-semiconductor-technology-and-ecosystem-in-japan/?ref=insidedeeptech.com); TSMC's N2 has been [in volume production since 4Q25](https://www.tsmc.com/english/dedicatedFoundry/technology/logic/l%5F2nm?ref=insidedeeptech.com).
- No mass-production customer is public, and [17 design partners](https://www.rapidus.inc/en/news%5Ftopics/information/20261005-2/?ref=insidedeeptech.com) are not the same as wafer orders.

Source: [Rapidus IIM page](https://www.rapidus.inc/en/iim/?ref=insidedeeptech.com) for the fab, EUV and pilot line; [Rapidus prototype release](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-achieves-significant-milestone-at-its-state-of-the-art-foundry-with-prototyping-of-leading-edge-2nm-gaa-transistors/?ref=insidedeeptech.com) for July 2025; [Rapidus June 2026 funding release](https://www.rapidus.inc/en/news%5Ftopics/information/20260605-2/?ref=insidedeeptech.com) for 424.95 billion yen; [VLSI Korea](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com) for the fiscal-year window and the customer status.

Notice the shape. Rapidus has a fab, tools and money. What it doesn't have on the public record yet is a working product-level chip or a named volume buyer.

## Why Japan built Rapidus

Japan once led the chip world, then fell out of leading-edge logic. Seoul Economic Daily, citing Reuters and Jiji, puts the plan bluntly: Rapidus aims to [leap from 40-nanometer technology straight to 2 nanometers](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) through its IBM partnership.

That's the point of the company. Japan wants a domestic source of the most advanced logic so it isn't fully dependent on Taiwan's TSMC, which [TrendForce describes](https://www.trendforce.com/news/2026/11/10/news-rapidus-reportedly-months-behind-on-2nm-sram-development-march-2028-mass-production-target-at-risk/?ref=insidedeeptech.com) as the core reason the state backs Rapidus.

The founding shareholders tell the same story. Toyota, Sony, NTT, SoftBank, Denso, Kioxia, NEC and MUFG Bank invested at founding and again in 2026, and the February 2026 round added [167.6 billion yen from 32 private companies](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-secures-267-6-billion-yen-in-funding-from-japan-government-and-private-sector-companies/?ref=insidedeeptech.com).

🗾

**Rapidus isn't TSMC Japan.** TSMC's Kumamoto fab, run by its JASM joint venture, is a separate project controlled by TSMC. Rapidus is a Japanese-owned company aiming at the leading edge, with a process developed with IBM rather than licensed from TSMC.

## The IBM 2nm partnership and imec

Rapidus didn't invent its process. In December 2022, IBM and Rapidus announced a joint development partnership to [further develop IBM's 2nm node for production at Rapidus's fab in Japan](https://www.rapidus.inc/en/news%5Ftopics/information/ibm-and-rapidus-form-strategic-partnership-to-build-advanced-semiconductor-technology-and-ecosystem-in-japan/?ref=insidedeeptech.com).

IBM's claim for the underlying technology is ambitious. In 2021, IBM said its 2nm chip was projected to deliver [45% better performance or 75% more energy efficiency than leading 7nm chips](https://www.rapidus.inc/en/news%5Ftopics/information/ibm-and-rapidus-form-strategic-partnership-to-build-advanced-semiconductor-technology-and-ecosystem-in-japan/?ref=insidedeeptech.com), per the joint release. That comparison is against 7nm, not against TSMC's 3nm or 2nm, so it doesn't tell you how Rapidus will rank today.

The two companies [expanded the deal to chiplet packaging](https://www.rapidus.inc/en/news%5Ftopics/news-info/rapidus-and-ibm-expand-collaboration-to-chiplet-packaging-en/?ref=insidedeeptech.com) in June 2024\. Rapidus also [joined imec's Core Partner Program](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-joins-imecs-core-partner-program/?ref=insidedeeptech.com) in April 2023 for advanced research access.

Here's why that matters. IBM hasn't run a high-volume leading-edge logic fab in years. Turning a research node into a high-yield production line is exactly the step where Rapidus is now reported to be stuck.

## The technology: 2nm GAA, EUV and single-wafer processing

Rapidus's 2nm process uses gate-all-around nanosheet transistors, the same family of structure TSMC uses in N2 and Intel calls RibbonFET in 18A. If you need the basics, Inside Deep Tech's [GAAFET nanosheet transistor guide](https://www.insidedeeptech.com/gaafet-nanosheet-transistors-full-guide/) explains why FinFETs ran out of room.

Patterning relies on EUV. Rapidus installed [Japan's first mass-production EUV scanner, an ASML NXE:3800E](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-begins-installation-of-japans-first-euv-lithography-machinery-for-semiconductor-mass-production-en/?ref=insidedeeptech.com), in December 2024 and completed its first EUV exposure on April 1, 2025, about three months after delivery, according to its [prototype release](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-achieves-significant-milestone-at-its-state-of-the-art-foundry-with-prototyping-of-leading-edge-2nm-gaa-transistors/?ref=insidedeeptech.com). Inside Deep Tech's [EUV lithography guide](https://www.insidedeeptech.com/euv-lithography-asml-machines-full-guide/) covers the machines and their limits.

The unusual part is how wafers move. Rapidus runs [fully single-wafer front-end processing](https://www.rapidus.inc/en/business/?ref=insidedeeptech.com): each 300mm wafer is handled one at a time, rather than in batches. The company argues that this yields more data per wafer, which feeds AI models that tune the process faster.

Rapidus brands the whole package RUMS, for Rapid and Unified Manufacturing Service. It combines design support, front-end wafer processing and back-end packaging under one roof, with the goal of [the world's fastest cycle times](https://www.rapidus.inc/en/business/?ref=insidedeeptech.com).

⚙️

**Single-wafer processing is a speed bet, not a cost bet.** Batch tools process many wafers at once and usually win on throughput per tool. Rapidus is trading some of that for faster learning and quicker turnaround on small, custom runs. That suits niche AI chips better than a high-volume phone processor.

## IIM-1 in Chitose: what's built and what isn't

IIM-1 sits in the Bibi World industrial park in Chitose, next to New Chitose Airport. Rapidus says it chose Hokkaido for [land to expand, abundant water and electricity](https://www.rapidus.inc/en/iim/?ref=insidedeeptech.com), including access to renewable sources.

The build was fast by fab standards. Groundbreaking came in September 2023, the cleanroom was finished in 2024, and by June 2025 Rapidus had [connected more than 200 advanced semiconductor tools](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-achieves-significant-milestone-at-its-state-of-the-art-foundry-with-prototyping-of-leading-edge-2nm-gaa-transistors/?ref=insidedeeptech.com). In July 2025 it announced its first 2nm GAA transistor prototypes with measured electrical characteristics.

Two more sites opened in April 2026\. The [Analysis Center](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-opens-analysis-center-and-rapidus-chiplet-solutions/?ref=insidedeeptech.com), next to IIM-1, handles physical, chemical and electrical analysis and reliability testing. Rapidus Chiplet Solutions, at Seiko Epson's Chitose plant, is the back-end packaging R&D hub, where Rapidus produced a prototype 600mm square RDL interposer panel.

Rapidus also wants a bigger cluster. CEO Atsuyoshi Koike said on November 4, 2026 that the company envisions [three additional fabs and an R&D facility](https://www.trendforce.com/news/2026/11/10/news-rapidus-reportedly-months-behind-on-2nm-sram-development-march-2028-mass-production-target-at-risk/?ref=insidedeeptech.com) near the existing plant, according to NHK via TrendForce. That's a vision, not a funded plan.

Be careful with the 1.4nm rumors. Rapidus said in November 2025 that reports about a 1.4nm factory were [speculation that didn't originate from the company](https://www.rapidus.inc/en/news%5Ftopics/information/statement-regarding-speculative-media-coverage-on-1-4nm-rapidus-foundry/?ref=insidedeeptech.com).

Most of the hardware milestones landed on time. The miss is in the step that turns transistors into working circuits.

## The November 2026 delay reports, explained

Bloomberg reported on November 10 that Rapidus had yet to produce functioning SRAM cells, leaving it [at least several months behind schedule](https://www.trendforce.com/news/2026/11/10/news-rapidus-reportedly-months-behind-on-2nm-sram-development-march-2028-mass-production-target-at-risk/?ref=insidedeeptech.com). Bloomberg also said Rapidus is working on dust and particle contamination in its cleanroom.

Jiji Press went further on November 11\. People familiar with the matter said Rapidus is struggling with [connecting transistors to one another and integrating them](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) with other components, and that yield progress is slow. A one-year delay to fiscal 2028 is being considered, Jiji said.

Why SRAM? It's the dense cache memory inside every processor, and it's one of the hardest structures to yield on a new node. VLSI Korea notes that a single advanced processor contains [hundreds of millions of SRAM cells](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com), so a working transistor alone can't make a product.

Rapidus's response was firm but thin on detail. It said it continues to devote its full efforts to [starting mass production in the second half of fiscal 2027](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com) and declined to share technical details, citing confidentiality. Germany's Golem reported that the [new overhead transport design](https://www.golem.de/news/2-nm-fertigung-rapidus-scheint-produktionsstart-verschieben-zu-muessen-2611-215085.html?ref=insidedeeptech.com) may be one factor behind the particle issue, which is speculation, not a finding.

⚠️

**Reported is not decided.** As of November 15, 2026, no formal change to the METI-certified plan has been announced. The first hard checkpoint is whether Rapidus or METI revises the fiscal 2027 date, per [VLSI Korea's tracking](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com). Until then, treat the delay as a credible risk, not a fact.

## The money: subsidies, equity and loans

Rapidus runs largely on state money. It comes in three layers.

First, research subsidies. NEDO has funded Rapidus's front-end and back-end programs since fiscal 2022\. Seoul Economic Daily, citing Reuters, says Japan provided [a combined 2.3 trillion yen in R&D commission fees](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com) across the last two years, with another 300 billion yen sought for next year.

Second, equity. The state's Information-technology Promotion Agency invested [100 billion yen in February 2026](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-secures-267-6-billion-yen-in-funding-from-japan-government-and-private-sector-companies/?ref=insidedeeptech.com) and [another 150 billion yen in June 2026](https://www.rapidus.inc/en/news%5Ftopics/information/20260605-2/?ref=insidedeeptech.com), equivalent to $943 million. In October, METI laid out [400 billion yen more through fiscal 2029](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com), which would take government equity to 650 billion yen.

Third, debt. The same report says Rapidus plans to [borrow 2 trillion yen from commercial banks](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com) to expand production lines, and that the extra equity is meant to make that borrowing possible. If the plan is approved, the Asahi Shimbun reported that total government support would reach 3.2 trillion yen by 2029, and METI envisions an IPO in 2031.

| Funding layer               | Amount            | When                  |
| --------------------------- | ----------------- | --------------------- |
| Founding capital            | 7.3 billion yen   | 2022                  |
| Private round, 32 companies | 167.6 billion yen | Feb 2026              |
| IPA equity, first tranche   | 100 billion yen   | Feb 2026              |
| IPA equity, second tranche  | 150 billion yen   | Jun 2026              |
| Planned extra state equity  | 400 billion yen   | FY2027 to FY2029      |
| R&D commission fees         | 2.3 trillion yen  | Last two fiscal years |
| Planned bank borrowing      | 2 trillion yen    | Not dated             |

Source: [Rapidus February 2026 release](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-secures-267-6-billion-yen-in-funding-from-japan-government-and-private-sector-companies/?ref=insidedeeptech.com) for founding capital, the private round and the first IPA tranche; [Rapidus June 2026 release](https://www.rapidus.inc/en/news%5Ftopics/information/20260605-2/?ref=insidedeeptech.com) for the second tranche; [Seoul Economic Daily, October 20, 2026](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com) for planned equity, R&D fees and bank borrowing.

Here's the problem. Much of that support is planned, not paid, and the bank loans depend on Rapidus hitting technical milestones that are now in question.

## Customers and partners: who's actually on Rapidus

This is the weakest part of the story. VLSI Korea notes that Rapidus [hasn't publicly named a mass-production customer](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com). What it has is a long list of partners.

- **Design partners.** In October 2026 Rapidus formed [17 Design Solution Associates](https://www.rapidus.inc/en/news%5Ftopics/information/20261005-2/?ref=insidedeeptech.com), including Cadence, Synopsys, Infosys, Wipro, HCLTech and Toppan, to help customers start early designs.
- **EDA and AI design tools.** Rapidus and Cadence are integrating agentic AI into Rapidus's Raads design suite, targeting [up to a 2x cut in design turnaround time](https://www.rapidus.inc/en/news%5Ftopics/information/20260717-3/?ref=insidedeeptech.com).
- **Engineering capacity.** HCLTech opened [two development centers in India](https://www.rapidus.inc/en/news%5Ftopics/information/20261026-2/?ref=insidedeeptech.com), in Bengaluru and Hubli, for mask design, PDK development and layout.
- **AI chip prospects.** Rapidus signed a [joint IP partnership with Tenstorrent](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-and-tenstorrent-agree-to-joint-ip-development-en/?ref=insidedeeptech.com) in 2023 and a [basic agreement with Preferred Networks and Sakura Internet](https://www.rapidus.inc/en/news%5Ftopics/information/realization-of-cloud-infrastructure/?ref=insidedeeptech.com) in 2025 for Japan-made AI infrastructure.
- **U.S. presence.** A Silicon Valley subsidiary, [Rapidus Design Solutions](https://www.rapidus.inc/en/news%5Ftopics/information/rapidus-announces-u-s-subsidiary-and-opens-silicon-valley-office-names-henri-richard-as-gm-and-president-of-rapidus-design-solutions-en-1/?ref=insidedeeptech.com), opened in 2024 under Henri Richard.

Partners help a foundry win customers. They aren't customers. TrendForce notes that some potential buyers worry that [if a switch to Rapidus failed, returning to TSMC could be difficult](https://www.trendforce.com/news/2026/11/10/news-rapidus-reportedly-months-behind-on-2nm-sram-development-march-2028-mass-production-target-at-risk/?ref=insidedeeptech.com).

Rapidus's realistic first market is small, custom AI and edge chips where turnaround time matters more than raw volume. That fits the RUMS pitch. It doesn't fit a flagship smartphone processor that needs huge, steady wafer volumes.

## Rapidus vs TSMC 2nm vs Intel 18A vs Samsung

Rapidus is entering a race the leaders have already started. The table uses public status only, with no invented specs.

Even on the official timeline, Rapidus would start volume production about two years after TSMC N2\. By then, TSMC plans to be moving to A14, as Inside Deep Tech's [TSMC A14 guide](https://www.insidedeeptech.com/tsmc-a14-1-4nm-nanoflex-pro-full-guide/) covers. For the incumbent's full roadmap, see the [TSMC 2nm full guide](https://www.insidedeeptech.com/tsmc-2nm-n2-a16-nanosheet-full-guide/).

On the flip side, Rapidus doesn't have to beat TSMC to matter. It has to produce working 2nm chips in Japan at a yield good enough for paying customers.

## Yield, wafer price and the economics

Yield is the share of chips on a wafer that meet spec. Independent director Yoshimitsu Kobayashi said in September 2026 that Rapidus targets a [mass-production yield of at least 80%](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com).

That's a demanding bar for a first-generation fab on a new node, and Rapidus hasn't disclosed current yields. Jiji's report that [yield progress is slow](https://en.sedaily.com/world/2026/11/11/japans-rapidus-weighs-one-year-delay-in-2-nanometer-chip?ref=insidedeeptech.com) is the only public signal, and it's anonymous.

Pricing is also unclear. In July 2026, after media reports on an estimated wafer price based on Koike's remarks, Rapidus said the figure [doesn't necessarily reflect the actual selling price](https://www.rapidus.inc/en/news%5Ftopics/information/20260709-2/?ref=insidedeeptech.com), because prices vary by specification and exchange rates. No official price exists.

## Inside Deep Tech's take

🧭

**Inside Deep Tech's take:** Rapidus has done the parts money can buy on schedule: a fab, an EUV scanner, 200-plus tools and a pilot line. The November reports point at the part money can't buy quickly, which is turning a licensed research node into working SRAM at yield. A one-year slip wouldn't kill Rapidus, since Japan treats it as strategic infrastructure, but it would stretch the gap to TSMC N2 from about two years to about three when Rapidus finally ships. Judge Rapidus on three things over the next 12 months: an announced working SRAM cell, a named paying customer, and whether METI formally changes the fiscal 2027 date.

## Honest limits of what is known

- **The delay reports are anonymous.** Bloomberg and Jiji cite unnamed people; Rapidus says its [target is unchanged](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com).
- **No yield data.** The only public number is a [target of at least 80%](https://www.vlsi.kr/en/rapidus-2nm-sram-delay-en/?ref=insidedeeptech.com), not a measurement.
- **No named volume customer.** Partner lists, including the [17 design associates](https://www.rapidus.inc/en/news%5Ftopics/information/20261005-2/?ref=insidedeeptech.com), aren't wafer orders.
- **IBM's performance claims are old benchmarks.** The [45% figure](https://www.rapidus.inc/en/news%5Ftopics/information/ibm-and-rapidus-form-strategic-partnership-to-build-advanced-semiconductor-technology-and-ecosystem-in-japan/?ref=insidedeeptech.com) compares IBM's 2nm with 7nm chips, not with TSMC N2.
- **Funding totals mix plans and cash.** The [3.2 trillion yen figure](https://en.sedaily.com/world/2026/10/20/japan-to-inject-additional-400-billion-yen-into-chipmaker?ref=insidedeeptech.com) includes requests that the Diet hasn't approved yet.
- **Single-wafer economics are unproven** at high volume, so cost per wafer versus TSMC is unknown.

---

Rapidus has turned Japan's leading-edge ambition into a real fab with real tools. The next 12 months decide whether it becomes a real foundry. If working SRAM and a first customer arrive before the end of fiscal 2026, the fiscal 2027 date survives. If not, Japan will face a harder question than when: how much more it's willing to pay to stay in the race.
