IBM and Japanese semiconductor manufacturer Rapidus are jointly researching 1-nanometer-class chips; the disclosure describes research, not production.

IBM’s chief executive disclosed the joint research at a Washington event. According to the supplied message, IBM CEO Arvind Krishna attended the September 11 event alongside Rapidus president Atsuyoshi Koike (小池淳义). Krishna said IBM and Rapidus were jointly developing 1-nanometer-class advanced chips.

The disclosure concerns a research effort rather than a manufacturing milestone. The message does not report production qualification, commercial shipments, manufacturing yield or wafer output. It also does not provide a process architecture, performance result or production schedule for the 1-nanometer-class work.

The joint chip research is distinct from another concept discussed at the event. Koike separately described consideration of a lunar semiconductor factory around 2040 and showed an AI-generated factory video. That presentation was a stated concept, not evidence of a commissioned facility or production capacity associated with the IBM research.
