Pravin. That is what I say,
, <<As things get smaller the trace resistance becomes larger, copper helps abate this as it is a better conductor. >>
Abate means it fights the increase in resistance with it's lower intrinsic resistance. It may not fully abate it as you may make the lines a lot smaller so they are higher in resistance anyway, even with copper.

<<In addition as things get smaller they get closer together and so signal coupling from trace to trace gets to be a bigger problem..with coppers' better conductivity they can increase the spacing >>

Again that is what I say. It is infact a balancing act with crosstalk(coupling between parallel lines and the ground planes) getting smaller as the lines get smaller and also getting smaller as the lines get further apart and getting smaller as the oxide layer insulation gets thicker. At the same time you are trying to make the whole thing smaller with more huighly conductive copper traces.

I think we had a terminology conundrum.

True get it good at 0.18 and you are better ablke to transition to 0.13. However they will be making good product at .18 and what if they run into serious problems going to .13? the problems Intel is now having with .18?
