9th International Symposium on Quality Electronic Design (isqed 2008)
Investigating the Design, Performance, and Reliability of Multi-Walled Carbon Nanotube Interconnect
March 17-March 19
ISBN: 978-0-7695-3117-5
In this paper, we develop a quantitative design technique for multi-walled carbon nanotube (MWCNT) based interconnect, which we utilize to examine the performance and reliability of future nanotube-based interconnect solutions. Leveraging an analytical RLC model for MWCNTs, we create the first closed-form formulation for the optimal nanotube diameter and nanotube bundle height. The results indicate that the proposed design method decreases delay by 21% and 29% on average compared to non-optimized MWCNTs and single-walled carbon nanotube (SWCNT) bundles. We also find that large diameter MWCNT bundles are significantly more susceptible to process variations than SWCNT bundles, which will have important reliability implications in future nano-scale ICs.
