Bh. Cheng et al., Exploration of velocity overshoot in a high-performance deep sub-0.1-mu m SOI MOSFET with asymmetric channel profile, IEEE ELEC D, 20(10), 1999, pp. 538-540
The electron velocity overshoot phenomenon in the inversion layer is experi
mentally investigated using a novel thin-film silicon-on-insulator (SOI) te
st structure with channel lengths down to 0.08 mu m, The uniformity of the
carrier density and tangential field is realized by employing a lateral asy
mmetric channel (LAC) profile. The electron drift velocity observed in this
work is 9.5 x 10(6) cm/s for a device with L-eff = 0.08 mu m at 300 K. The
upward trend in electron velocity can be clearly noticed for decreasing ch
annel lengths.
