摘要

摘要介绍了在SOI衬底上新兴的20nm门长finfet中单界面捕获电荷的影响的全面三维模拟研究。详细研究了捕获电荷的位置对随机电报信号(RTS)振幅的影响。与特定陷阱位置相关的RTS振幅取决于鳍中的复杂电流密度分布,并由“本地”统计变异性源(如金属栅粒度(MGG),线边缘粗糙度(LER)和随机离散掺杂剂(RDD))修改。

Statistical distribution of RTS amplitudes in 20nm SOI FinFETs
This abstract presents a comprehensive 3D simulation study on the impact of a single interface trapped charge in emerging 20nm gate-length FinFETs on an SOI substrate. The impact of the location of trapped charges on the Random Telegraph Signal (RTS) amplitudes is studied in detail. The RTS amplitude associated with particular trap position depends on the complex current density distribution in the Fin and is modified by `native' statistical variability sources such as metal gate granularity (MGG), line edge roughness (LER), and random discrete dopants (RDD).
