IBM Unveils Nanostack Chip Architecture That Builds Upward to Overcome Scaling Limits

Jul 10, 2026

IBM Research has introduced a new microchip architecture called Nanostack that builds transistors vertically rather than horizontally, aiming to overcome spatial limitations in scaling transistor density. The approach stacks components to increase density without expanding the chip's footprint.

Why it matters: This vertical stacking approach could enable continued performance improvements in microchips beyond the limits of traditional planar scaling.
