One way to save Moore's Law from an unpleasant and industry-disrupting demise is for manufacturing process technology developers to make a series of changes at a given node – say 20-nm – but label each successive change with a smaller number.
In that way double patterning of deep immersion lithography can continue to produce chips that are in processes technologies that are labeled 16-nm, 14-nm, 10-nm and so on, thereby keeping Moore's law moving forward.
And as long as some feature on the chip can be measured at the
appropriate dimension it should be possible to find a way to justify the

Of course, the IC die-area savings and cost advantages that we have become used to from previous process node transitions would not accrue with these forthcoming node transitions. However, as chip designers at the leading edge are becoming more interested in power savings than area savings as long as the successive process nodes produce ICs with lower power consumption all may be well.
To acknowledge the end of Moore's law is to acknowledge what most of the semi industry has known for the past decade - the business model made possible by scaling is now obsolete. More than Moore will be upon us all. Peter mentions low power since mobile is now king, but what if you aren't in the mobile market? I think there is room for many different kinds of innovation.
This does sound like smoke and mirrors, but Moore's law doesn't account for getting the same number of "better" things. For instance, if you get the same number of transistors as the last node but they use 50% less power, how do you measure that in terms of Moore's law? If you stack two chips on top of each other to get twice and many transistors in the same "space" does that count?
Precisely the type of dodgy thinking that led to the demise of British manufacturing industry since the '60s and their living off W. Europe and the US as low-cost English speakers, middle-men and parasites who lie to start wars.
EUV saturated so much of the total R&D spectrum that little bandwidth was left for alternative approaches. The decision to stick with EUV defies logic, especially in an industry that is so careful about managing risks. The fact that EUV sources are still at this late date 10 to 20 times too weak for HVM should indicate that the technology is not tractable. Furthermore, if a true 200 watt source was available for long term testing, the exposure tool would certainly have to undergo major changes to accommodate the thermal loading.
There is a economics paper by the National Bureau of Economic Research by Robert J. Gordon titled "Is U.S. Economic Growth Over? Faltering Innovation Confronts the Six Headwinds". This paper describes how Moore's Law fueled the third of three "industrial revolutions" and now that it is coming to a close, will result in a completely different worlds from an economic perspective. Interesting reading. I don't agree with all of his conclusions, but I do think he has captured what we've all been seeing in the electronics industry for the past five years.
