Performance comparison between carbon nanotube and copper interconnects for GSI

Abstract

The performances of minimum-size copper and carbon nanotube interconnects are compared for various ITRS generations. Results offer important guidance regarding the nature of carbon nanotube technology development needed for improving interconnect performance. Since wave propagation is slow in a single nanotube, nanotube-bundles with larger wave speeds must be used. At the 45nm node (year 2010), the performance enhancement that can be achieved by using nanotube-bundles is negligible, and at the 22nm node (year 2016) it can be as large as 30% and 80% if carbon nanotubes with electron mean free paths of 5~ and 1 0~. respectively, can be fabricated.

Effects of suspended multi-walled carbon nanotubes on daphnid growth and reproduction

“…MWNTs are viewed as attractive new materials for processor architecture beyond the 22 nm node (Naeemi et al 2005). A ring oscillator using a single SWNT was tested in 2005 (Chen et al 2006).…”

Inductance modelling of SWCNT bundle interconnects using partial element equivalent circuit method

“…In the previous studies [11][12][13][14][15][16]25], it was claimed that kinetic inductance dominates the overall bundle inductance and hence the impact of magnetic inductance on overall bundle inductance was neglected. But it can be noticed from Fig.…”

“…The inductance (magnetic L M-CNT and kinetic L K-CNT ) per unit length for an isolated SWCNT are derived in [15]. While calculating the magnetic inductance of the bundle in [11][12][13][14][15], it was assumed that an individual SWCNT behaves as a conductor above ground plane and its self inductance was calculated. However, partial inductances obtained through PEEC method conceptually involve magnetic flux between a conductor and infinity [26,27].…”

“…Significant progresses have been achieved in the characterization of interconnect performances of single SWCNT and bundled SWCNT interconnects [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. To use nanotubes in future VLSI applications, we must develop models to characterize their behaviour.…”

Carbon Nanotube Capacitors

“…They are cylinders of graphene that can exhibit radii on the order of nanometers. CNTs exhibit a number of properties that make them attractive as potential horizontal and vertical interconnects in future integrated circuits (Naeemi et al, 2004, Naeemi et al, 2005, Raychowdhury & Roy, 2004. The same properties allow CNTs to be used to create a new capacitor structure suitable for use in future integrated circuits (Budnik et al, 2006).…”
