Analysis of Cu-Graphene Interconnects

Due to its ultrathin feature, graphene has been recently proposed as diffusion barrier layer for Cu wires. This paper is geared toward developing an equivalent single-conductor (ESC) transmission-line (TL) model for analysis of Cu-graphene interconnects, i.e., Cu wires encapsulated with graphene bar...

description Due to its ultrathin feature, graphene has been recently proposed as diffusion barrier layer for Cu wires. This paper is geared toward developing an equivalent single-conductor (ESC) transmission-line (TL) model for analysis of Cu-graphene interconnects, i.e., Cu wires encapsulated with graphene barriers. Based on the ESC TL model, electrical performances of Cu-graphene interconnects are examined and evaluated. It is shown that the time delay and temperature rise can be reduced by replacing the conventional diffusion barriers in the Cu/low-k interconnect with the graphene barriers.
