摘要：

This work examines different components of leakage current in scaled n-MOSFET's with ultrathin gate oxides (1.4-2.0 nm), Both gate direct tunneling and drain leakage currents are studied by theoretical modeling and experiments, and their effects on the drain current are investigated and compared. It concludes that the source and drain extension to the gate overlap regions have strong effects on device performance in terms of gate tunneling and off-state drain currents.
