WebAl/sub 2/O/sub 3/ (EOT=22.7 /spl Aring/) gate dielectric layer formed by Atomic Layer Deposition (ALD) process have been characterized for sub-100 nm CMOS devices. The gate leakage current was 3 orders of magnitude lower than that of SiO/sub 2/ and the hysteresis of C-V curve was not observed. However, the negative fixed charge induced … WebThe diffusion profile of Cu ions in a dielectric material is first simulated and the resulting flatband voltage shift 共⌬VFB兲 is compared with the experimental results obtained by C-V measurements after bias-temperature stressing 共BTS兲. The evolution of the Cu concentration in dielectric materials is evaluated using a one-dimensional ...
WebApr 1, 2008 · Metal-oxide-semiconductor ABSTRACT We have examined an origin of the flatband voltage ( V FB) shift in metal-oxide-semiconductor capacitors by employing … WebThe flatband voltage shift, corresponding to gate-voltage at a half of maximum capacitance (C max ), 28,[44][45] [46] was evaluated instead of that defined as gate-voltage at the maximum in G ...
WebFor example, assume a 0.01cm 2, 50pF, p-type MOS-C with a flatband voltage of -5.95V; its N BULK of 10 16 cm-3 corresponds to a W MS of –0.95 V. For this example, Q EFF can be calculated to be 2.5 × 10-8 C/cm 2, which in turn causes the threshold voltage to shift ~5V in the negative direction. Note that in most cases where the bulk charges ... WebSep 1, 2011 · Abstract. In metal-gate/high- k stacks adopted by the 45 nm technology node, the flat-band voltage ( Vfb) shift remains one of the most critical challenges, particularly the flat-band voltage roll-off ( Vfb roll-off) phenomenon in p-channel metal-oxide-semiconductor (pMOS) devices with an ultrathin oxide layer. In this paper, recent …
WebIt is further shown that the Ni-silicided poly-Si gate electrodes with the interlayers produce similar equivalent oxide thickness and a positive shift of flatband voltage (VFB), compared to the samples without the interlayers.
