This is kind of interesting for all those follong the scaling trend recently from 130nm to 90nm. ie: northwood to prescott
"This lithographic definition of process technology is absolutely meaningless," said Meyerson, referring to the custom of labeling manufacturing processes with a number designed to correspond to the minimum geometries defined in the process or the half-pitch of the most aggressive interconnect structures. "Somewhere between 130-nm and 90-nm the whole system fell apart. Things stopped working and nobody seemed to notice." He added, "Scaling is already dead but nobody noticed it had stopped breathing and its lips had turned blue."
