Rapidus is bidding Japan's entire return to leading-edge logic on one fab in Chitose, Hokkaido, and the schedule now turns on a 2027 mass-production target for a 2nm process that no high-volume customer has yet committed to.
Since opening the IIM-1 pilot line in April last year, the company has run wafers through Japan's first mass-production-grade EUV scanner, produced a 2nm gate-all-around prototype that reached its expected electrical characteristics in July, and closed a ¥267.6 billion funding round in February that made the Japanese government its largest shareholder. CEO Atsuyoshi Koike said the same month that more than 60 companies are in talks over 2nm capacity, but not one has yet signed a volume agreement. Given that its entire production base is the single IIM-1 facility, this leaves Rapidus with no diversification and no fallback site if the node doesn’t go ahead as planned.
However, the fab has the hopes of an entire nation pinned on it, and its plans are promising. Here's the breakdown.
