Thanks for the article.

I had already seen most of the Intel slides, but I was wondering about various details, especially about which is the meaning of the "enhanced copper", which has replaced the former cobalt layers. After reading your article, that has become clear enough.



There has been much speculation about whether the choice of cobalt had something to do with the shortcomings of the 10 nm Intel CMOS process. The fact that Intel 4 has reverted to copper, even if with improved linings, seems to confirm that supposition.

The high resistance of the cobalt interconnections is likely to have been one of the reasons for the much too low clock frequencies of Cannon Lake and Ice Lake.

The other serious problem of the 10 nm process, the very low yields, might have been determined mainly by their choices for photolithography, where they have attempted to get very small pitches without using EUV.
