Monolithic 3D Silicon Chips Achieve Near-Perfect Yields At Low Temperatures

University of Illinois Team Advances Monolithic 3D Chip Design

Illinois researchers achieve monolithic 3D silicon stacking with three layers of 625 transistors each at 98-100% yield, staying within the 400°C thermal budget. Monolithic 3D integration enables denser, faster AI accelerators and GPUs without further shrinking, shifting hardware roadmaps from 2D to 3D architectures.
