IC中多余物缺陷对信号串扰的定量研究

该文研究了铜互连线中的多余物缺陷对两根相邻的互连线间信号的串扰，提出了互连线之间的多余物缺陷和互连线之间的互容、互感模型，用于定量的计算缺陷对串扰的影响。提出了把缺陷部分单独看作一段RLC电路模型，通过提出的模型研究了不同互连线参数条件下的信号串扰，主要研究了铜互连线的远端串扰和近端串扰，论文最后提出了一些改进串扰的建议。实验结果证明该文提出的信号串扰模型可用于实际的电路设计中，能够对设计人员设计满足串扰要求的电路提供指导。

Quantitative Studies Redundant Object Defect in IC for Signal Crosstalk

This paper studies the signal crosstalk due to redundant object defect of adjacent copper interconnects. The models of coupling capacitance and mutual inductance between redundant defect and interconnects are presented, and it can be used to quantitatively calculate the influence of defect on crosstalk. In the experiment model, defect is regard as a separate section RLC circuit. Signal crosstalk is studied under the conditions that are various parameters of interconnect using the model. The far crosstalk and near crosstalk of the copper interconnects are studied. Finally, some advice improved signal crosstalk is put forward. Experiment results show that the presented model can be used actual circuit design, and can guide designer to design circuit for satisfying crosstalk requirements.
