OT (somewhat): infohq.com July 3 - CPU makers experiencing problems moving to copper manufacturing processper Techweb. < Editor's Note: Most CPUs today are manufactured using aluminum. Copper interconnects are supposed to enable higher speeds and smaller form factors, however the manufacturing process is extremely difficult. Apparently, copper will contaminate aluminum and silicon and must be segregated during manufacturing.> While IBM and Motorola claim to be getting yields as high as 50% from their copper CPU manufacturing process (with 60 -70% yield considered normal for the current aluminum process), a spokesperson for Intel said he didn't expect copper manufacturing to make a significant impact in the industry until 2001. (In 2001, Intel will move to a 0.13 micron copper process. Intel uses aluminum in its current 0.25 and 0.18 micron processes.) This does not bode well for AMD, which claims they will use copper manufacturing in their 0.18 micron Athlon K-7 to be manufactured in early 2000 (aluminum is being used to manufacture 0.25 micron K-7s now). <Please see our editorial Can AMD Deliver the Athlon K-7? for more information.>
