IBM and Siemens Collaborate on Research to Advance Nanostack Architecture

IBM and Siemens will develop virtual models and fabrication tools to speed nanostack toward production, building on a design that packs nearly 100 billion transistors.

  • On Wednesday, IBM and Siemens announced a research collaboration to advance Nanostack, IBM's three-dimensional transistor architecture, aiming to accelerate manufacturing and design capabilities for future production.
  • IBM unveiled the Nanostack architecture earlier this year, a 3D design that vertically stacks and staggers transistors to shift semiconductor scaling from 2D to 3D—a new industry paradigm.
  • Nanostack currently packs nearly 100 billion transistors at a 7 angstrom node, using different material combinations within stacked layers to independently optimize performance and power efficiency of each transistor.
  • Siemens will contribute electronic design automation and simulation expertise to develop advanced virtual models, allowing IBM and Siemens to optimize designs and address fabrication challenges before physical production.
  • Scaling semiconductors into the angstrom era demands co-optimization between device physics and manufacturing software, positioning Nanostack to support AI and emerging technologies over the coming decade beyond the current 7 angstrom node.
