高k栅介质MOSFETs的二维阈值电压模型
2D Threshold-Voltage Model for High-k Gate-Dielectric MOSFETs
摘要
Abstract
New boundary conditions and a 2D potential distribution along the channel of a high-k gate-dielectric MOSFET,including both the gate dielectric material region and the depletion region,are given. Based on this distribution, a 2D threshold-voltage model with thefringing-field and short-channel effects is developed for a high-k gate-dielectric MOSFET. The model agrees well with experimental data and a quasi 2D model, and is even more accurate than the quasi 2D model at higher drain voltages. Factors affecting the threshold behavior of the high-k gate-dielectric MOSFET are discussed in detail.关键词
