Method and system for design and modeling of vertical interconnects for 3DI applications

摘要

A system and method for design and modeling of vertical interconnects for 3DI applications. A design and modeling methodology of vertical interconnects for 3DI applications includes models that represent the frequency dependent behavior of vertical interconnects by means of multi-segment RLC scalable filter networks. The networks allow for accuracy versus computation efficiency tradeoffs, while maintaining correct asymptotic behavior at both high and low frequency limits. In the framework of the model it is shown that a major effect is pronounced frequency dependent silicon substrate induced dispersion and loss effects, which is considered in through silicon via (TSV) parallel Y-element parameters, including capacitance and conductance.
