2-6-1 Structural Evolution Theory —— Why Can't the Faucet Be Shut Off Tightly?
Transistor scaling caused quantum leakage, failing 2D architecture. TSMC's 3D FinFET dominated 16-3nm. At 2nm, FinFET hit physical limits, forcing a shift to GAA (Gate-All-Around). GAA, via suspended nanosheets, provides 360° perfect control, fully resolving leakage, offering channel width flexib...
