Wafer‐Scale 3D Integration for High‐Density Multi‐Valued Neuromorphic Logic
Advanced Science, Volume 13, Issue 63, 12 November 2026.Wafer‐scale 3D vertically integrated multi‐valued logic (MVL) circuits are realized by monolithically integrating a Te/IGZO heterojunction FET with an engineered Te pull‐up FET. Heterointerface‐mediated transport and optimized current matching enable stable ternary operation, while vertical stacking reduces circuit footprint and interconnect complexity,
