Being pedantic but shouldn't the graphic for the 'Roadmap' say "Next-Gen <7nm" or "7nm-"? That looks like things will begin getting bigger again in a few year

  basically 7nm+ means tweaks to the process with improved speed and power consumption, stays 7nm from [0] """ TSMC plans to introduce a second improved process called 7nm+ a year later, which will introduce some layers processed with EUVL. This will improve yields and reduce fab cycle times. The 7nm+ process will deliver improved power consumption and between 15-20% area scaling over their first generation 7nm process.

    Where do wikichip get their info? Is it rumours since I don't see any sources listed?That's not what I heard about 7nm+.

  To add to other answers, at both GlobalFoundries and TSMC: - 7nm has have very limited extreme ultraviolet patterning on larger features of the chip - 7nm+ will have significantly more EUV patterning which will allow shrinking some stuff that wasn't for 1st process iteration because yields would be too low - should have slightly higher density, possibly higher clocks/lower power draw.
