电路级热载流子效应仿真研究

Circuit-level Lifetime Simulation Based on HCI

随着集成电路制造工艺的不断进步,沟道长度、结深、栅氧厚度等特征尺寸不断减小,而电路的电源电压没有按比例减小,易造成MOSFET的电流-电压特性退化,需要提前在设计阶段加以考虑。对电路长期可靠性问题中的热载流子效应(HCI)进行了仿真研究。

As VLSI fabrication technologies move into the deep submicron regime, feature size such as the channel length, the junction depth and the gate oxide thickness, is reducing without proportional scaling of the power supply voltage. This degrades the current-voltage characteristics of the MOSFET. The paper presents a investagation of circuit-level HCI simulation.
