Rapidus began reviewing an internal plan on Nov. 11, 2026, to delay mass production of its 2-nanometer logic chips by one year to fiscal 2028 following prototype fabrication setbacks.

The Tokyo-based foundry had targeted the second half of fiscal 2027, ending in March 2028, to initiate commercial runs at its Innovative Integration for Manufacturing (IIM-1) plant in Chitose, Hokkaido.
