2024年4月22日 · Enter the gate-all-around (GAA) transistor architecture, which extends device scaling while increasing chip performance and reducing power. GAA devices began to emerge at 3nm and are dominant at 2nm. Currently, high-performance mobile is leading the way in GAA adoption, with hyperscale servers and high-performance CPUs following closely behind.

什么是 GAA 环绕式栅极技术晶体管？这篇文章IT之家就和大家一起了解一下。 1、从 3D FinFET 到 GAA，5nm 之后就靠它了. 作为取代 3D FinFET 晶体管的全新技术，其实 GAA 环绕式栅极技术晶体管和 3D FinFET 有着千丝万缕的联系，因此我们需要从 3D FinFET 晶体管说起。

Gate-all-around FET (GAA FET) is a modified transistor structure where the gate contacts the channel from all sides. It’s basically a silicon nanowire with a gate going around it. In some cases, the gate-all-around FET could have InGaAs or other III-V materials in the channels.

2022年10月3日 · GAA transistors are poised to become part of the most advanced chip designs in the coming years. Because these transistors can be manufactured at a desirable cost for chipmakers, they will help keep the mass production of advanced chips affordable, while driving up the performance of new electronics, 5G connectivity, gaming, graphics, AI ...

Gate-All-Around transistors are a multi-gate field effect transistors type where a silicon nanowire gate moves around the channel by further scaling down FinFET. The Gate-All-Around structure enables a vertical stacking of a planner channel, which improves the effective width of the channel and enhances transistor drive current.

Fundamentally, GAA provides a rethinking and rearchitecting of basic transistor design in which the silicon channel inside a transistor is completely encircled by gate material instead of having it be covered by gate material on just three sides as with current FinFET designs.

2024年4月30日 · Enter the gate-all-around (GAA) transistor architecture, which extends device scaling while increasing chip performance and reducing power. GAA devices began to emerge at 3nm and are dominant...

2019年11月20日 · GAA transistors will find their way into next-generation semiconductor applications that require high performance and low power consumption, from AI to Big Data, autonomous driving, and the Internet of Things.

The GAA Concept Gate-All-Around technology is a novel approach to transistor design that encases the semiconductor channel with gates on all sides. Unlike the conventional planar transistors where the gate is placed on top of the channel, or the FinFET design where the gate wraps around three sides of a fin-shaped channel, GAA transistors as ...

2020年11月19日 · Gate-all-around, or GAA transistors, are a modified transistor structure where the gate contacts the channel from all sides and enables continued scaling. Such transistors are referred to as gate-all-around, or GAA, transistors, and different variants have been proposed. Early GAA devices will use vertically-stacked nanosheets. They are ...
