Electrical properties of carbon nanotube via interconnects for 30nm linewidth and beyond
Review current status of CNT via interconnect performance, reliability, and key factors limiting its electrical performance Report using measured resistances for individual CNTs with diameter of 50 nm to obtain CNT resistivity and CNT-metal contact resistance Review using measured resistances for CNT vias with widths ranging from 150 nm to 60 nm to project 30 nm via resistance Report comparisons of projected 30 nm CNT via resistances from the two independent approaches and with their Cu and W counterparts Assess measured current capacities of individual CNTs and CNT vias
