Katherine,
I was reading an article on your page, semiconductoronline.com by Gail Purvis concerning Europe ramping Copper when I came across this:
"AMD's $1.9bn Fab 30 with staff at around 1,500 (design team of 60 are focused on chipset design) demonstrated its 1.1GHz version of the Athlon processor involving six levels of 0.18micron technology using copper interconnects (technology developed with Motorola) in early February and expects first revenues by the end of the second quarter 2000.

Fab 30 had ramped up with aluminium and 0.25 micron geometry, moving to copper interconnects in the last quarter of 1999. It used the K6 as the vehicle to ramp up the technology and moved to 0.18 on K7 in mid October. Ultimately Fab 30 will will be capable of producing 5,000 8-in. wafers weekly."
---
I was not aware that Dresden (FAB 30) had ever ramped up on .25 Aluminum K6s.
Is the author saying thay Dresden shipped .25u K6s? To my knowledge, Dresden hasn't shipped yet. Perhaps the .25 Aluminum K6s' were practice or the author is in error?

Reagrds, Jim

Not sure what you mean regarding polishing compound. You always optimize the slurry for whatever it is you want to polish. Usually there's a tradeoff between polishing rate/throughput and uniformity.

Katherine, are you suggesting that the polishing problems with copper can't be overcome?
