Intel's Roadmap Includes 4nm Fab in 2022 259
Precision submits "Intel Corp., the largest maker of chips in the world, has outlined plans to make chips using 4nm process technology in about thirteen years. According to Intel, integration capacity of chips will increase much higher compared to fabrication process."

They're looking at moving away from using silicon as a substrate. I can't remember if artificial diamond or something else is the proposed replacement.

Just sayin'. Your product management/marketing folks at these firms are often very plugged in to the tech side of things (I should know, being one of them).

Forget about the limitations of die shrink, what about the limitations of quantum mechanics? I was under the impression that 4 nm is getting awefully close to the point where quantum tunneling makes tansistors unworkable. As in, when you detect a signal, you can't tell if it's there because it should be or because an electron just jumped the gap.

If you read the two articles, it's clear that there are significant issues with gate sizes, materials, and quantum tunneling that make even 11nm basically a pipe-dream. It's the same reason we don't see 10ghz processors - they've hit limits that current science can't easily get past.

Funny is how everything changes after 2012, they will have a different type of transistors. Maybe the guy really thinks things won't matter after 2012 - nut-case.
Just in case, I ask you to hold them to their other words too:

Next year we are going to see 10GHz processors, this is going to be an interesting exercise.
Maybe Tom's Hardware or some other brave soul will manage.
Semiconductor roadmap (Score:5, Informative)
There have been formal semiconductor roadmaps to the future since 1992. There's an consensus roadmap [itrs.net] updated annually by an industry group.
This isn't a blue-sky thing. It tells all the players what they need to do to keep up their part of the technology. The fab-equipment people, the device physics people, the etching people, the mask people, the substrate people, the design tools people, etc. all have to push their parts forward. The roadmap tells them how far each piece has to be pushed.
These roadmaps are available for past years, and you can see how the industry has tracked the roadmap. It's reasonably close for any five year period. The big change in the last decade is that heat dissipation is starting to dominate the problem. The roadmap now focuses on memory devices, which have low activity per cell compared to compute elements and aren't yet power-limited.
The current consensus is that the improvements to known technology can get down to 22nm, and then it gets hard. The roadmap assumes CMOS transistors; other devices are discussed, but aren't factored into the mainline predictions.
