rapidus
A Japanese advanced-logic foundry development program. Rapidus is a Japanese semiconductor company developing advanced logic manufacturing and associated customer services. Its IIM research and manufacturing hub is located in Chitose, Hokkaido. The company describes its leading process direction as 2nm-class gate-all-around technology. That node name identifies the intended platform generation, while customer-ready foundry capability also requires manufacturing qualification, design enablement, and a sustainable commercial production flow.
The pilot line is a documented development milestone. Rapidus states that IIM groundbreaking occurred in September 2023, an ASML NXE:3800E EUV system was installed in December 2024, and the pilot line commenced operation in April 2025. These events document the progression from construction toward process development. An installed scanner and an operating pilot line do not by themselves establish mature yields, large commercial wafer volumes, or qualification for every prospective customer design.
The platform extends beyond transistor fabrication. Customers need process design kits, libraries, memory and interface IP, verification support, packaging options, and test access. Rapidus’ April 2026 announcement describes an analysis center and Rapidus Chiplet Solutions as additions to its development environment. Such facilities address important parts of a foundry ecosystem. Their opening remains distinct from the qualification and volume manufacturing of a particular customer’s finished product.
The production date is a stated target. The cited IIM overview and April 2026 announcement identify 2027 as the planned transition to mass production. This entry treats that date as the company’s target, rather than a milestone already achieved. Pilot operation, prototype performance, customer tape-outs, risk production, and sustained volume shipments should each be reported using the relevant dated evidence instead of being combined into one launch claim.
Commercial success requires repeated execution. A new foundry must turn device results into predictable timing, power, reliability, defect levels, delivery schedules, and customer support. Process learning and customer design development proceed together, while capital intensity and product demand shape the business. Rapidus is therefore best evaluated through demonstrated technical progress and qualified customer production, rather than through a nominal node number, a single tool installation, or a future capacity objective.
