Abstract :
Recent advances in the growth of carbon nanofibers (CNF) using plasma-enhanced chemical vapor deposition (PECVD) allows for the potential use of these novel structures in backend-of-line (BEOL) interconnect applications. Reliability data is presented for vertically aligned CNF array structures as well as temperature-dependent electrical conductance measurements of both CNF arrays and CNF heterojunction structures. CNF arrays are presented as a possible new via material, while CNF heterojunctions present a promising new architecture for diode array and memory applications.
