Can Carbon put copper down for the count???

Copper interconnects carry current in today's integrated circuits, but in the nanometer-size future, the metal just won't do the job. At December's IEEE 2010 International Electron Devices Meeting, in San Francisco, European researchers plan to announce that they're one step closer to a replacement. Nanotubes made of carbon, if grown in dense bundles, can transport large quantities of charge through tiny channels reliably. As part of the European ViaCarbon project, a team led by Jean Dijon, the head of nanotube research at the French government research organization CEA LITEN in Grenoble, says they've grown the densest bundles yet, packing 2.5 trillion carbon nanotubes per square centimeter. The density of their interconnects is within an order of magnitude of what's needed for replacing copper. In the future, such bundles have the potential to exceed copper's current-carrying capabilities by a factor of 100.

Copper needs a replacement particularly in the narrow pegs, called vias, that connect the silicon surface to the chips' wiring and connect one layer of wiring to another. According to the 2009 International Technology Roadmap for Semiconductors, engineers predict that as the features on chips shrink, not only will copper vias be more difficult to manufacture and suffer from more resistance, but by 2015 they may not work at all.

Vias start as holes etched into a layer of dielectric. Depositing copper ions from an electrolyte fills the holes, but at the nanometer scale, the metal could cling to the walls, leaving gaps. Also, the vias' walls must be lined with a metal nitride barrier to keep copper from seeping into the surrounding dielectric. The liner wastes space and increases resistance.
Engineers are also concerned that copper vias will prove unreliable at future nanometer-scale dimensions. Skinnier copper means that current density and resistivity both increase. Together, those factors cause the interconnects to heat up and break. "For each new generation, as dimensions decrease, current densities increase and will soon approach the copper limit," says Murielle Fayolle-Lecocq, a microelectronics engineer who worked on the new nanotube vias at France's CEA-LETI.

Carbon nanotubes have the perfect shape for fitting into future vias' voids: "Naturally, they're tall and thin," says the leader of the ViaCarbon project, John Robertson, who is an electrical engineering professor at the University of Cambridge, in England.

The team's goal was to grow dense bundles of narrow nanotubes. Although nanotubes are usually championed for their ability to carry charge long distances with little resistance, quantum interactions in individual nanotubes can actually give them more resistance than the copper interconnects they're meant to replace.

Bundles of parallel nanotubes can solve that problem by providing multiple channels for electricity to flow. That lowers the nanotubes' effective resistance, making them seem like many individual resistors connected in parallel, says Robertson. Using nanotubes with only a few layers and carefully selecting the material on which they grow will ensure that the tubes have a small diameter and thus increase the possible bundle density.

If packed densely enough, these bundles can carry about 1 billion amperes per square centimeter, around 100 times copper's limit. But they haven't reached that ideal yet. Although the team has packed the tubes 10 times as densely as others, Robertson says, to match copper's conductivity they will need to increase the density by another factor of 10, to around 30 trillion nanotubes per square centimeter.

Adrian Ionescu, head of the Nanolab at École Polytechnique Fédérale de Lausanne and a contributor to the nanotube via project, adds that the team will need to improve the tubes' contact with the metal horizontal interconnects in integrated circuits. Ionescu believes that in the future, nanotubes—or a combination of nanotubes and graphene sheets—could replace the copper in even these horizontal interconnects.

"They still have to increase the density by quite a bit," says Kaustav Banerjee, director of the Nanoelectronics Research Lab at the University of California, Santa Barbara, who was not involved in the research. But, he adds, "this is definitely a significant improvement and very positive news."

Gadgets, Oh Gadgets!

A short poem composed by me which describes, my views on gadgets…

Click here to experience the change...

Gadgets, Oh Gadgets!
We live on thee,
For thou art the future,
We strive to be.

You are captivating,
Your presence is fascinating,
We maketh thee,
Thou in turn maketh us.

Are we so dependent?
To depend on thee?
Or is it thee that’s,
Compelling us to use thee.

Gadgets, Oh gadget!
We live on thee,
But thou no longer the future,
Cause future is what we maketh…


An old saying goes this way,

“We are what we eat.”

But today, no matter what you eat, it’s always what gadgets you have that determine what you are. An iPad in your hand boasts that you are with the technological advances that are taking place. A high end mobile phone resembles your status symbol.
It’s pretty common nowadays when we meet someone and exchange telephone numbers, and the other person says that he has no mobile phone, you without any second thoughts think that the fellow is sick not to carry a mobile.

The world is fast growing into a place which will have more gadgets than cockroaches! From headphones to PCs, just count the number of electronic devices around you which you use daily. I’m sure the count won’t be below 10. So 10 things which you can’t live without are GADGETS!!!

But do gadgets actually tell others what we are? It all depends on ones thinking and view on life. For a person who believes money is the most important part of life, will think owning a costly and flamboyant gadget develops his portrait in front of people. On the other hand the one who thinks that the values which he/she holds are important is least bothered to care which gadget may increase their face value, cause their values are the one which is will help set their value.

To my opinion gadgets are important. In today’s world things happen smoothly with them. They help but they are not the need. Gadgets may lift your value in front of others in the first meet, but slowly as their luster fade it is your personality which shines and puts a permanent impression on the minds of people.

Got to keep moving on...

Early morning by the river,
I sit and quiver,
To the unholy wind,
That blew within,
It’s a demon,
Which ruined this human,
For all I remember is the darkness,
After the surreal.

It was a mistake gaze,
That caught me amazed,
It was the start of the game,
The first half of the blame,
Back then I never knew,
You lead to tears, no few,
Cause I never knew that,
Life could be a demon’s avenue.

The day was bright,
And my spirits high,
It couldn’t had been better ,
For life to turn this bitter,
You walked away from me,
Throwing away all the memories,
Now all I see is your picture,
Girl, I want to see you no more.

As I sit by the river and quivered,
She held me from behind and uttered,
‘Keep all your worries in my pocket,
I’ve got a key so we can lock it,
I swear I won’t let them escape.’
‘But how do I believe, you wouldn’t be another mistake?’
She whispered, ‘Yesterday’s gone,
And you got to keep moving on…’

I Doubt...

They say that I’m insane,
Losing my mind for you is lame,
Do they matter to me? I asked,
Will they ever understand me? I doubt.

Your smile is what my heart beats for,
Your voice is what it craves for,
I see you all the time,
But did you ever find me, anytime?

I follow you here and there,
Wherever you go, I trail,
Did you ever look back to see me?
Or was the thing only in me?

Fleeing from the fright,
That they may be right,
You always listen to them,
But does it matter when I say, ahem?

They say that I’m insane,
Losing my mind for you is lame,
Does it matter to you? I ask,
Will you ever understand this? I doubt…
