|Abstract:||We report the first comparison study of BTI characteristics of nTFET and nMOSFET with the same high-k/metal gate stack fabricated on the same wafer. NTFETs demonstrate smaller ΔV TH and G m loss in comparison with the nMOSFET under the same PBTI stress. We speculate that the trapped electrons density in HfO 2 gate dielectric above the tunnel junction (TJ) is lower than that above the channel, which leads to the superior PBTI characteristics in nTFET. © 2012 IEEE.|
