Impact of Process Variations on Delay in Carbon Nanotube Based Bus Interconnects At Different Technology Nodes

This paper presents the impact of process variations in carbon nanotube based advanced bus interconnects such as single walled carbon nanotube (SWCNT), multi walled carbon nanotube (MWCNT) and mixed carbon nanotube bundle (MCB). The impact of temperature variations on paracitics of interconnects for variable interconnects at different technology nodes is analyzed. From the analysis, it reveal that the mixed bundle carbon nanotube offering the lower paracitics even higher temperatures compared to SWCNT and MWCNT which leads to lower delay and crosstalk effect when it is used in bus interconnects. Further we have also done delay analysis by changing the bundle area, number of shells and metallic ratio of three interconnect structures with the insertion of obtained parasitics using empirical formulas. It is proven that the mixed CNT (MCB) interconnect structures offered a lesser delay compared to other CNT interconnect structures. All the analysis has been done using MATLAB at 22nm and 32nm technology nodes.

Multi Walled Carbon Nanotube

AbstractSingle-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) were functionalized with 3,4-diaminobenzoic acid via “direct” Friedel-Crafts acylation reaction in PPA/P2O5 to afford ortho-diamino-functionalized SWCNT (DIF-SWCNT) and MWCNT (DIF-MWCNT). The resultant DIF-SWCNT and DIF-MWCNT showed improved solubility and dispersibility. To improve interfacial adhesion between CNT and polymer matrix, the grafting of ABPBI onto the surface of DIF-SWCNT (10 wt%) or DIF-MWCNT (10 wt%) was conducted by simple in-situ polymerization of AB monomer, 3,4-diaminobenzoic acid dihydrochloride, in PPA. The resultant ABPBI-g-MWCNT and ABPBI-g-SWCNT showed improved the mechanical and electrical properties.

This paper presents single walled carbon nanotube (SWCNT) interconnects with air as dielectric medium. We treat CNT interconnects as a discrete (fractal) media for the first time where continuum based differential equations fail to capture the physics at nanoscale and hence, we use discrete partial differential equations in this work. We have analyzed the effect of air gaps (AG) on performance factors like temperature dependent resistance R(T) of CNTs and hence the R(T)C delay of the interconnects. We have first calculated the temperature coefficient of resistance (TCR) of CNTs and analyzed the trend of changing resistance at different ambient temperatures. The R(T)C delay shows that CNT/AG interconnects can operate satisfactorily up to 500K. We then compare the R(T)C delay with ITRS predictions from 17nm to 8nm technology nodes. We have also calculated the chip area used by CNT/air-gap interconnects and found that they take up to 83% lesser area than the conventional Cu/low-k interconnects.

ABSTRACTGeometrically controlled single-walled carbon nanotube (SWNT) and multi-walled carbon nanotube (MWNT) networks were fabricated by a width confinement technique to characterize their electrical characteristics. The results demonstrated non-linear resistance decay with the number of conducting channels. The current-voltage characteristics at high field were studied until the electrical breakdown took place. Large current (∼2 mA), low resistance (∼5 KΩ) and current densities exceeding ∼108 A/cm2 were demonstrated from multi-channel MWNT networks confined in a 10 μm × 15 μm trench. Additionally, chronological SEM imaging was used to identify the breakdown sequences in the carbon nanotube networks, which revealed a strong tendency for CNT breakdown to occur in the vicinity of CNT-CNT intersections. Our results offer insights for interconnect applications using CNT networks.

The Impact

The mutual result of the magnetic field and Marangoni convection against the thin liquid film of Casson fluid, blood-based carbon nanotube nanofluid has been fruitfully discussed in this article. The influence of various model constraints is focused on velocity, heat transfer, pressure distribution, skin friction and Nusselt number through graphical illustration. In addition, we witness that the thermal field of liquid raises with the growing value of [Formula: see text] and this upsurge is more in single-walled carbon nanotubes and is more dominant than multi-walled carbon nanotubes. The controlling approach of the homotopy analysis method has been used for velocity and temperature distribution. For authentication, the achieved results have been associated with the numerical (ND-Solve) method and displayed. This investigation shows that the velocity profile in the case of Casson fluid single-walled carbon nanotube–blood nanofluid is comparatively less affected and the temperature field of single-walled carbon nanotube–blood nanofluid dominates multi-walled carbon nanotube–blood nanofluid.
