It moved the complexity from lithography to alignment

That is it, this is fundamentally a 7nm process leveraged potentially to a 1.4nm (claimed) scale.

Makes you wonder what is possible when applied this to much smaller node sizes. Interesting times ahead.

  • It seems fundamentally easier to do the alignment in the lithography step as you only have get it correct once in the mask instead of correct for every chip every time.
