They mean half-pitch rather than cell size, I guess.

They will probably call 18 x 18 1Z. It's 13% area reduction.

1z seems to be 16 nm apparently. I do wonder, why go beyond double patterning with any new patterning technique, just for one generation.

And this last 1Z generation is not even double the density of the prior one 1Y. If it's going to be the final generation, at least make it look like one last hurrah or going out with a bang, like 10-13 nm, and get more of your money's worth.

So finally, a company is giving up shrinking. Intrinsic variability at small nodes is a well know problem, and the complications in litho does not help. The return back to 40 nm to get 3D devices is certainly a milestone.

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
