Abstract

The electron velocity overshoot phenomenon in the inversion layer is experimentally investigated using a novel thin-film silicon-on-insulator (SOI) test structure with channel lengths down to 0.08 μm. The uniformity of the carrier density and tangential field is realized by employing a lateral asymmetric channel (LAC) profile. The electron drift velocity observed in this work is 9.5×106 cm/s for a device with Leff=0.08 μm at 300 K. The upward trend in electron velocity can be clearly noticed for decreasing channel lengths.
