  7. Abstract:
  8. The process of contracting the chips will lead the increasing of impurity concentration, decreasing the bias voltage and threshold voltage to make stable the electrical field. For using the advantage of lesser dimensions of the total circuit using decreasing bias voltage lead the dimension of the wires to be decrease also. Therefore, once the parasitic effects of wires, the RC delays of wires and the noise of power transmission will enhance obviously. With this contracting by process, electrical resistance of interconnect will enhance also. The reason of this matter is that the area chip will decrease significantly. While the operational frequency increases the effect of inductance should be under consider. Hence, parasitic effects of wires will play an important role in the chip’s total performance.To resolve these kind of issues the revision on-chip interconnect has been used during the history of semiconductor technology, which one of the samples of this revision is to replacing Copper instead of Aluminum during the past years. Now, to solve this existing delay issue we shall use Carbon Nano Tube (CNT) or Graphene Nano Ribbon (GNR) instead of metal interconnect. The graphene is the thinnest and most stable material in which it shows an interesting thermal and electrical properties. This material is a two dimensional material in which the structure of it is same as a regular honey box. GNR would be shaped by cutting Graphenes in ribbon’s structure base that can be used for transmission lines applications. Because of having higher mean free path, GNRs can have more thermal conductivity and the ability of carrying currents as a basic interconnect for VLSI
