The companies plan to develop virtual models to simulate performance, optimize designs and address manufacturing challenges before chips are built. The announcement describes techniques under development, not a production-ready technology.

IBM says its current nanostack design could fit nearly 100 billion transistors in an area the size of a fingernail and is at a 7-angstrom node. These are company-described architecture characteristics; the collaboration did not announce manufacturing yield or a commercial launch timeline.

## Data

### Research collaboration

IBM and Siemens will research virtual modeling, simulation and lithography for IBM’s nanostack transistor architecture.

Methodology: The event is IBM’s announcement dated October 14, 2026, of a new research collaboration with Siemens. This is a separate joint research initiative from the previously announced nanostack PDK plan; it does not mean production has begun or performance has been independently validated.
