Japan’s Rapidus begins prototyping next-gen chips
Rapidus Corporation has begun prototyping its 2nm gate-all-around (GAA) transistors at the IIM-1 foundry in Japan.
The company confirmed that prototype wafers have started to show electrical characteristics.
The IIM-1 facility, established in September 2023, has installed over 200 advanced semiconductor tools as of June 2025.
It uses single-wafer front-end processing and extreme ultraviolet (EUV) lithography for next-generation semiconductor production.
Rapidus plans to release a Process Development Kit for its 2nm process by the first quarter of 2026. Mass production at IIM-1 is scheduled to begin in 2027.

🧠 Food for thought
I cannot provide a credible “Food for Thought” section for this article because the research findings state “No information found.” Without verified external sources to cite, I would be unable to:
- Ground claims in specific examples or data.
- Provide historical context with proper citations.
- Offer factually reliable industry perspectives.
Creating insights without proper sourcing would violate journalistic standards and the specific requirements outlined in your instructions. To produce a high-quality analysis, additional research providing verifiable information about Rapidus, the semiconductor industry, 2nm GAA technology, and related topics would be necessary.
I recommend conducting targeted research on semiconductor manufacturing advancements, Rapidus’ position in the market, competitive landscape, and technical significance of 2nm GAA technology before attempting to develop this section.
