Re: pros/cons from copper.

Bill,

Thank you for your reply.

I'm still wondering if copper will be particularly helpful for a processor that consumes a lot of power at very low voltage. Is there any sense to the notion that the Pentium and K6 cores would benefit more from a shrink than Athlon will, while Athlon will get more of a benefit from copper than the other two?

I believe that AMD's strategy for next spring is .18 Al K6 at FAB25, and .18 Cu Athlon at FAB 30. I'm wondering if there are technical reasons for this or if that arrangement is just convenient.

Dan

Bill,

I don't think you are on the mark here. Due to copper's lower resistance, you can decrease the thickness of interconnect traces and still have acceptable resistance. This results in smaller capacitor area, and hence capacitance, between interconnect lines, while maintaining minimum spacings.

Also, to me, one of the biggest benefits of going to copper in 0.18u is that you have it down to a science when migrating to 0.13u.

Pravin.
