| Outline of Final Research Achievements |
We successfully achieved the fabrication of not only the current loading specimen with several carbon nanotubes (CNTs) but also the CNT-networked specimen, which has large expectation for application to electronic devices in near future. The damages due to evaporation and electromigration of carbon atoms were observed in the CNT-networked specimen and it was found that the dominance of the damage mechanisms depended on operating condition.
We were able to predict the failure location depending on operating condition by means of numerical simulation using a parameter formula governing CNT damage. Furthermore, a simplified method of reliability evaluation for electromigration damage was developed considering usage environment, that is line shape and passivation thickness.
