I'm not an expert, but I think metals on chips are already almost ideal. The way to make a chip faster would be to use substrates that allow channels to form faster. Superconductors wouldn't help with this. Notice that IBM is using a copper interconnect process for G4s. Copper is almost twice as conductive as aluminum, but they're not getting very high clock speeds. Better conductors have lower resistance, which does mean less heat... -Tom On December 01, 1999 at 23:04:10, Ricardo Gibert wrote: >On December 01, 1999 at 22:07:35, Tom Amburn wrote: > >> >> A few years ago I was reading somewhere that scientist were trying to discover >>Superconductivity, it said the benifits of this technology would lead to a >>thousand times increase in computer speed.
