摘要
Threshold voltage (V-th) variability due to random dopant fluctuations in intrinsic channel silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistors (MOSFETs) with an ultrathin buried oxide is investigated by three-dimensional device simulation. It is found that, in contrast to bulk and doped channel SOI MOSFETs, V-th variations in intrinsic channel SOI MOSFETs decrease with increasing V-th. A device design guideline for intrinsic channel SOI MOSFETs is also discussed. (C) 2010 The Japan Society of Applied Physics
