FinFET
Fin field-effect transistor, an architecture in which a silicon fin is stood upright so that the gate controls the channel from three sides. It was the dominant transistor architecture before GAA and supported performance improvements across multiple process nodes.
Timeline (last 90 days)
Short-channel effects must be solved by enhancing the gate's electrostatic control over the channel at the device structure level, which is the fundamental motivation for the emergence of FinFET and GAA.
FinFET forms the channel into a vertical thin fin, with the gate covering and controlling the channel from three sides, greatly enhancing gate control and effectively suppressing short-channel effects.
FinFET became a key technology for extending Moore's Law.
From planar to FinFET to GAA, the logic of transistor evolution has always been to bring the gate closer to the channel and wrap it more comprehensively, achieving less leakage through better control.
In GAA (Gate-All-Around) transistors, the gate fully surrounds the nanosheet or nanowire, achieving four-sided encapsulation, whereas in FinFET the gate wraps around the fin-shaped silicon structure on three sides.
At the minuscule scale of the angstrom level, the traditional FinFET architecture is difficult to sustain, and the industry has broadly adopted GAA transistors to control leakage and improve performance.
