Hot-Carrier Induced Degradation in Submicron MOS Transistor

초록

The hot-carrier induced degradation in very short-channel MOSFET was studied systematically. Under the traditional DC stress conditions, the threshold voltage shift (${\Delta}Vt$) and the transconductance degradation (${\Delta}Gm$/(Gmo-${\Delta}Gm$)) were confirmed to depend exponentially on the stress time and the dependency between the two parameters was proved to be linear. And the degradation due to the DC stress across gate and drain was studied. As the AC dynamic process is more realistic in actual device operation, the effects of dynamic stresses were studied.
