<Paul - re: The "poisoning" problem is at the heart of the limitations of copper.>

What about silver or gold, why is everybody focusing on copper?
Can someone explain?

That's a great explanation of the limitations of copper. I hadn't thought about the width of the diffusion barrier involved, though I would expect that in time there will be improvements in the barrier thickness.

Paul,

If a material could be found that acts as both a diffusion barrier and a low-k dielectric, would the copper interconnect scaling be as good as the aluminum ones?
