Abstract

Planar fully depleted (FD) devices with thin Buried Oxide (BOX) offer the unique ability to incorporate effective back biasing which is a key enabler to build a versatile multi-Vt technology. From a dynamic standpoint, forward back bias lowers Vt and thus boost device performance, whereas reverse back bias increases Vt and thus decreases leakage. From a static point of view the back gate allows fine Vt tuning. Here we propose and evaluate a back gate implant scheme that enables a full use of the back bias.
薄埋氧化物20nm FDSOI晶体管的地平面优化
具有薄埋氧化物(BOX)的平面全耗尽(FD)器件提供了独特的整合有效背偏置的能力,这是构建多功能多vt技术的关键推动因素。从动力学的角度来看,正向偏置降低了Vt,从而提高了器件的性能,而反向偏置增加了Vt,从而减少了泄漏。从静态的角度来看,后门允许精细Vt调谐。在这里,我们提出并评估了一种能够充分利用后偏置的后门植入方案。
