Graphene interconnect for nano scale circuits

The role of interconnect in an integrated circuit is to enable effective passing of clock and other signals in addition to providing power to various parts of the circuit on a chip. The advent of sub-quarter-micron IC technologies has forced dramatic changes in the design and manufacturing methodologies for integrated circuits and systems. The paradigm shift for interconnect which was once considered just parasitic but can now be a dominant factor for integrated circuit performance provided the greatest impetus for change of existing methodologies. Copper, which is presently used as the interconnect material. Cu interconnect dimensions begin to come into the range of mean free path of electron typically 40nm. This results in surface and grain boundary scattering. Owing to these scattering phenomena resistivity, of Cu begins to increase. This limitation of copper interconnects is driving research for alternative interconnect materials and technologies for next-generation ICs. Nanotubes, Graphene, and Nanowires and Carbon Nano Tubes are some of the new materials suggested as an alternate to overcome these problems. Here in this paper we have analysed the various properties of graphene to use as an interconnect. Graphene has been attracting wide attention owing to its superb electronic, thermal and mechanical properties.
