在半导体领域，GAAFET技术，全称为门极全环绕场效应晶体管，代表了FinFET技术的先进演化和芯片设计的未来方向。其核心特征在于，栅极完美包裹沟道四周，实现了对电流的全方位精准控制，大幅提升了晶体管的性能同时显著降低了功耗。与现有技术的对比 FinFET与GAAFET：一场技术革新的竞赛 沟道控制：GAAFET通过其全面环绕的栅...
为了克服FinFET的局限性,预计电流通道将全部四个侧面而不是三个方向的栅极包围,从而减少漏电流。 由于包裹所有这些通道的形状,它被称为“全环绕栅极 (GAA)。 全环绕栅极 (GAA) 是一种晶体管架构,可克服 FinFET 架构的挑战。GAA 采用 FinFET 设计并将其侧向转动,使通道是水平的而不是垂直的。与FinFET架构中的...
The semiconductor device structure includes a fin structure formed over a semiconductor substrate and a gate structure formed across the fin structure. The semiconductor device structure also includes an isolation feature over a semiconductor substrate and below a portion of the gate structure and two ...
However, further reduction in finFET dimensions leads to limitations in the drive current and electrostatic control. In planar transistors, the width of the channel could be increased to drive more current and switch on and off faster. However, evolution of CMOS designs to standard cells with ...
GAA即全环绕栅极(Gate All Around),用来取代此前先进制程上长期采用的FinFET(鳍式场效应晶体管)。GAA被称为新一代半导体的核心制程技术,能够提升数据处理速度、电力效率和晶体管性能。IBM曾在2021年宣布成功研制出全球首款2纳米芯片,该款芯片已率先采用GAA技术。台积电则计划在2025年量产的2纳米工艺中应用GAA技术。

Introduced by major foundries around the 3nm/2nm nodes when further scaling of finFET devices became untenable due to issues such as channel width variations, the approach allows for the vertical stacking of planar channels, leading to a notable increase in the effective channel width. By stacking...
#三星宣布已量产3纳米芯片 三星电子有限公司30日宣布,该公司已经开始在其位于韩国的华城工厂大规模生产3纳米半导体芯片,是全球首家量产3纳米芯片的公司。与前几代使用 FinFET 的芯片不同,三星使用的 GAA(Gate All Around)晶体管架构,该架构大大改善了功率效率。三星公司称,与传统的5纳米芯片相比,新开发的第一代3...
