What Rapidus does
Rapidus Corporation (Rapidus株式会社) is a Japanese semiconductor manufacturer founded in August 2022 by a consortium of eight major Japanese corporations and the Ministry of Economy, Trade and Industry (METI), with the stated mission of reviving Japan's advanced logic semiconductor manufacturing capability and producing the world's most advanced 2-nanometer gate-all-around (GAA) logic chips. Headquartered in Tokyo with its manufacturing hub at the IIM-1 (Innovative Integration for Manufacturing) facility in Chitose, Hokkaido, the company began pilot-line operations in April 2025 and is targeting mass production in fiscal year 2027. Core technology is sourced through a strategic partnership with IBM at the Albany Nanotech Complex in New York, where approximately 150 Rapidus engineers were trained on the 2nm GAA process, supplemented by an MOU with imec (Belgium), an IP partnership with Tenstorrent, and Japanese national R&D programs led by NEDO.
The company's product platform is built around 2nm GAA logic semiconductors produced using EUV lithography (ASML NXE:3800E, installed December 2024 — the first volume-production-ready EUV system in Japan) and delivered through the RUMS (Rapid and Unified Manufacturing Service) business model, which integrates front-end wafer processing, back-end chiplet packaging, and AI-driven design support into a single, short-cycle-time foundry offering. The back-end leg is anchored by Rapidus Chiplet Solutions (RCS) inside the Seiko Epson Chitose plant, developing 600mm panel-level RDL interposers; the design leg is anchored by the "Raads" (Rapidus AI-Agentic Design Solution) suite, comprising an LLM-based Raads Generator for RTL design data generation and a Raads Predictor for Power, Performance, and Area (PPA) estimation, all operating under a Design-Manufacturing Co-Optimization (DMCO) framework. North American customer engagement is delivered through Rapidus Design Solutions, a wholly-owned sales and customer-support subsidiary established in January 2024 in Santa Clara, California.
Rapidus is a private, pre-revenue company whose revenue mechanics will be a foundry service model selling wafer capacity to fabless chip designers rather than its own branded products. As of June 2026, cumulative capital raised reached approximately ¥424.95 billion (roughly $2.7 billion USD equivalent), drawn from Japan's Information-Technology Promotion Agency (IPA), NEDO grants, and a consortium of more than 32 private-sector Japanese investors that include Sony Group, Toyota, SoftBank, NTT, Canon, Fujitsu, Honda, Denso, Kioxia, Seiko Epson, Fujifilm, Kyocera, Dai Nippon Printing, Sumitomo Mitsui Banking, and MUFG Bank. The Japanese government holds 11.5% voting rights and a "golden share" with veto power over key corporate decisions, with the right to take up to 60% control if the company encounters financial or operational difficulties; three Japanese megabanks are additionally negotiating up to ¥2 trillion in loans.

Rapidus product offering
Product offeringCore offering
Rapidus is a Japanese semiconductor foundry developing and manufacturing 2nm gate-all-around (GAA) logic semiconductors at its IIM-1 facility in Chitose, Hokkaido, Japan. Through its RUMS (Rapid and Unified Manufacturing Service) model, the company integrates chip design support, front-end wafer processing, and back-end 3D chiplet packaging into a single short-turnaround-time foundry service. Pilot line operations at IIM-1 commenced in April 2025, and full-scale mass production of 2nm logic chips is targeted for 2027.
Product overview
Rapidus offers a single integrated foundry platform built around its 2nm Gate-All-Around (GAA) logic semiconductor manufacturing, delivered through the RUMS (Rapid and Unified Manufacturing Service) business model. The core product — 2nm GAA logic semiconductors — is produced at the IIM-1 (Innovative Integration for Manufacturing) pilot line in Chitose, Hokkaido. This front-end capability is tightly coupled with back-end packaging and chiplet integration through Rapidus Chiplet Solutions (RCS) and its 600mm Panel-Level Packaging technology, with physical/chemical/electrical characterization provided by the Analysis Center. Customer-facing design is supported by Raads (Rapidus AI-Agentic Design Solution), an AI/ML-based EDA suite (Raads Generator for LLM-driven RTL generation and Raads Predictor for PPA estimation), operating under the DMCO (Design-Manufacturing Co-Optimization) framework that links customer design directly to Rapidus's manufacturing process. North American customer engagement is delivered through Rapidus Design Solutions (RDS). Together these named offerings form a unified design-to-mass-production platform rather than a loose catalog of separate services.

Rapidus competitors and assessment
Company assessmentOthers
- IBM: Strategic technology partner licensing 2nm GAA process IP to Rapidus and hosting engineers at Albany Nanotech. Not a foundry competitor, but a critical technology enabler and a board-level connection via Outside Directors.
- ASE Technology Holding: Largest outsourced semiconductor assembly and test (OSAT) provider, with advanced packaging capabilities comparable to Rapidus Chiplet Solutions. Relevant as a benchmark for advanced packaging scale and as a partner/competitor for chiplet integration demand.
- Cadence Design Systems: Second major EDA vendor and a partner/competitor for Rapidus's design-support tooling. Comparable as an adjacent design-ecosystem player whose customer relationships Rapidus must navigate.
- Synopsys: Largest EDA vendor whose tools Rapidus's Raads suite complements and partially competes with. Relevant as both a tool supplier/partner and the dominant incumbent whose installed base Rapidus must integrate with.
Direct peers
- TSMC: World's largest pure-play foundry, also pursuing 2nm GAA logic production. Direct competitor for any advanced-node fabless customer and the benchmark Rapidus must match on yield, cost, and PDK maturity.
- Intel Foundry Services: Intel's external foundry business, with 18A/14A nodes targeting similar customers as Rapidus's 2nm. Direct competitor for US/allied fabless demand and a technology benchmark for GAA and backside power delivery.
- Samsung Foundry: Samsung's contract manufacturing arm, also developing 2nm GAA logic. Competes head-to-head with Rapidus for leading-edge foundry customers and is similarly investing in advanced packaging and AI-EDA workflows.
- SMIC: China's largest foundry, currently constrained at mature nodes by US export controls. A long-term competitor in the broader foundry landscape, though not yet at the 2nm node Rapidus is targeting.
Broad incumbents
- GlobalFoundries: Large US-based foundry focused on mature and specialty nodes rather than 2nm. Relevant as a competitor for fabless customers who choose not to migrate to the leading edge and as a comparison for foundry business models outside Asia.
- UMC: Taiwanese foundry focused on mature and specialty processes. Comparable as an incumbent pure-play foundry, though not competing at the 2nm node, providing a baseline for foundry unit economics outside the leading edge.
