Web11 Jul 2007 · The effect on the “hump” of interface states localized at the edges is also analysed and it is found that a degradation of the edge interfaces leads to a “hump” …
Web1 Oct 2024 · This paper presents a comparative study of VLSI circuits operated in subthreshold and the impact of matching and hump-effect in a mature 180nm process. … Web21 Nov 2008 · The stress-induced hump in the subthreshold region is observed and is attributed to the edge transistor along the channel width direction. The electric field at the corner is higher than that at the channel due to thinner gate insulator and larger electric flux density at the corner.
There are two main causes for the abnormal hump behavior owing to the device driving stress. The first is the constant voltage/current driving stress applied at the gate electrode, which is similar in character to that of the pixel driving transistors in the OLED display. Figure 2 shows various I–V characteristics … See more To understand the anomalous hump phenomena in Figs 2 and 3, a 2D numerical TCAD Atlas simulation method was used to calculate the device characteristics. Figure 4a,b show the density of the states … See more In the evaluation of the device characteristics, it was found that the hump phenomenon occurs only when the defect state appears in a specific location with a specific energy. … See more Up to this point, the discussion has been centered on the generation or increase of the defect states in the density of states as the cause of the hump. The occurrence of the channel edge … See more WebAbstract: A new method allowing the automatic characterization of the subthreshold hump effect (Sallagoity et al., IEEE TED vol. 43, no. 11, pp. 1900-6, 1996) is presented in this …
Web1 Jul 2011 · The total ionizing dose radiation induced subthreshold leakage current increase and the hump effect under four different irradiation bias conditions including the worst case (ON bias) for the transistors are discussed. The high electric fields at the corners are partly responsible for the subthreshold hump effect.

At 150 krad (Si), the leakage current curve is nearly flat. When the TID accumulated to 500 krad (Si), the off-state leakage is approximately 6 orders of magnitude higher than the corresponding pre-irradiation value. christmas tree appetizers pinterestWeb1 Dec 2024 · The hump-effect is almost negligible against Vg stress (≤ 20 V) within 3000 s. However, as Vg stress becomes larger than 20 V, the hump in the subthreshold region is clearly observed.
