Japanese contract chipmaker Rapidus will work with 17 semiconductor design companies to help prospective customers develop their own custom chips, Nikkei reported Sunday, according to a summary by South Korea's Financial News. The alliance is meant to widen Rapidus' customer base ahead of planned mass production of 2-nanometer chips in the second half of fiscal 2027.

What Happened

Named partners include Toshiba Information Systems, Dai Nippon Printing, TOPPAN and the Japanese design-service companies NSW and Mavis Design, along with U.S. design-software makers Synopsys and Cadence Design Systems and India's Infosys, Financial News reported, citing Nikkei. The full list of 17 companies and any commercial terms were not given in the coverage available to us.

The partners will support work across the design process, from logic design, which defines what a chip does, through physical design and architecture. The target is companies that want application-specific chips for products such as cars and production equipment but lack engineers with advanced chip design experience.

Why It Matters

A foundry can only fill its fabs if customers arrive with finished designs. Large chip companies have their own design teams, but many potential Japanese customers, such as automakers and equipment manufacturers, do not. By lining up design houses and electronic design automation vendors, Rapidus is trying to lower the barrier for those companies to commission chips on its 2nm process rather than buy off-the-shelf parts.

Synopsys and Cadence supply the software used to design nearly all advanced chips, so their participation helps make Rapidus' process usable with standard tools. Dai Nippon Printing and TOPPAN, best known for printing, are also major producers of photomasks, the templates used to pattern chips.

Context

Rapidus was founded in 2022 with heavy government backing to bring leading-edge logic manufacturing back to Japan. Its 2nm process builds on technology developed with IBM, and its first fab is in Chitose, Hokkaido, where it began running a prototype line in 2025. It has received about 3 trillion yen in cumulative government support, and 32 private companies had invested a combined 167.6 billion yen by March, according to Financial News.

Winning steady orders is widely seen as its biggest challenge. TSMC and Samsung Electronics already run similar networks of design-support partners, and TSMC's includes more than 20 design firms, Financial News reported. Rapidus is building its ecosystem while those rivals are already producing chips at comparable process nodes for large customers.

What to Watch

The measure of the alliance will be whether it produces signed production orders before 2nm mass production begins in the second half of fiscal 2027. Watch for Rapidus to name the remaining partners and the first customers whose designs come through the program, and for any further government funding tied to securing demand.
