current in lightly-doped drain (LDD) NMOSFET with 1.4 nm gate oxide fabricated by 90 nm complementary metal oxide semiconductor (CMOS) process was studied in depth.High-precision semiconductor parameter analyzer was used to conduct the tests.Law of variation of the direct tunneling (DT) current ...
In this paper we address the growing issue of gate oxide leakage current (I/sub gate/) at the circuit level. Specifically, we develop a fast approach to analyze the total leakage power of a large circuit block, considering both I/sub gate/ and subthreshold leakage (I/sub sub/). The int...

昨天已经讲完了栅极材料的演变(Gate Electrode),当然伴随它一起的自然就是栅极介质层(Gate Dielectric),记住我讲的是栅极介质层,不是我们平常讲的栅极氧化层(Gate Oxide),早期我们讲的MOSFET的介质层就是我们狭义讲的Oxide,但是随着Moore's Law的scale down,我们需要不断的降低我们的oxide厚度来换取低的开启电压(栅...
leakage/delay tradeoff curveGate oxide tunneling current (I/sub gate/) is comparable to subthreshold leakage current in CMOS circuits when the equivalent physical oxide thickness (T/sub ox/) is below 15 /spl Aring/. Increasing the value of T/sub ox/ reduces the leakage at the expense of ...

However, such devices will be susceptible to a more profound leakage mechanism due to carrier tunneling through the gate oxide. Consequently, the gate oxide tunneling current has emerged as the major component of the leakage power consumption of nanoscale CMOS devices. In the case of an important...
We report the use of photo-enhanced chemical (PEC) technique to form high-quality metal oxide semiconductor (MOS) devices made of gallium oxide (Ga2O3)/gallium nitride (GaN). Gate leakage current density as low as 210-7 A/cm2 at a bias field up to 2 MV/cm is observed in the GaN ...
