This copper technology is really a hype.

There is no dramatic merit in perform today in going to copper. Although the trace resistance is reduced, the junction resistance is still dominant!

Junction resistance + trace resistance = junction resistance.

I am not saying that copper would have no benefit. As Yousef has already pointed out last year, shrinking the geometry each generation actually increases the trace resistance. When the feature size is small enough, copper's 30-40% lower resistivity would eventually play a very important role. That is still years and many generations of reductions away.
