3-D Flexible Computer Chips
Roland Piquepaille writes "Engineers at the University of Wisconsin-Madison have isolated a single-crystal film of semiconductor from the substrate on which it is built. Then they transferred this very thin film — 200 nanometers thick — on plastic. Both sides of the film can host active components and several layers can be stacked, opening the way to very powerful 3-D flexible computer chips. Besides computer chips, this technique could be used for solar cells, smart cards, RFID tags or active-matrix flat panel displays."
... bringing us that much closer to the roll-up computer screens of Tek War.
Great show, man. Shatner was amazing

Heat dissipation is a major issue in cpus.. imagine if you could integrate your cpu within the heatsink's mesh at a monocrystaline level.
It would be a revolution in cooling efficiency.
VLC FOR MAC IS DYING! IF YOU DEVELOP, PLEASE SAVE IT!!
Anyone else read this and think it was some sort of flexible platform for 3-D acceleration?
So one could possibly make the registers have a "Z" axis and have "real" 3-D address space. Just a thought...
So does that mean we geeks will finally start wearing $1000.00 clothing just like supermodels? (albeit clothing that runs at dual clock speeds of 6.5Ghz ...)
--I gots 99 problems but a new machine ain't one!
AMD! Asus! Whoot! 6 years!
but won't. Call me when the technology is even remotely ready for commericalization.
How we know is more important than what we know.
Heat dissipation is only a significant issue in a very small number of CPUs like x86s and PowerPCs. Most CPUs you'll encounter in your average day (phone, car, mouse, PDA, refridgerator, washing machine, air conditioner, ...) use very little power and you don't heat up that you can notice.
Engineering is the art of compromise.
Moore's law will be able to keep marching on.
Hopefully these tricks, and others, will be commercially available by the time it becomes impractical to cram any more cores on a single chip.
I'll get tons more performance using this instead of my 1D chip in half-life!!!
This is not new - this is known as "susbtrate transfer process" and has been practiced for year. One company doing very advanced work in this is Philips:

First two paper hits I found in google:

Many companies are also working on substrate transfer processes to build silicon wafers with selective crystal orientation. Among them IBM and Soitec.
Why isn't this in YRO? After all, The Man could be using it to watch us shopping....
Does anyone have any ideas, besides clothing, as to how this could be useful? As I see it most devices have a hard screen, which makes them inherently inflexible.
Philosophy.
In other news Geeks overclocking clothes causes fire and personal injury.
They say this can be used for solar cells too. Imagine what 300 billion dollars investment could have done to make this a reality. We're like the 3rd generation of rich kid, the one that pisses away the fortune on gambling and yahts instead of doing something productive with it.
Presumably the CPU in larger devices like my washing machine is properly placed and can use the entire body of the machine to cool it, but in general electric circuits of any kind will produce heat under load.
Saying it just PC cpu's is idiotic. All cpu's will get warm, just because some you use are small enough and cooled well enough that you don't notice it doesn't mean they won't overheat if you remove the cooling.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
He's Back! Back from vacation, fresh faced and fancy free! Ladies and gentlemen, I give you MR. ROLAND PIQUEPAILLE! Give him a big hand!
(by the way, I spell-checked this in Word. PIQUEPAILLE was not flagged as a bad word... ???)
victoria's secret is now a hardware store...
"no, hon, that wasn't your manliness: my bra's cpu is just overheating again"
... and myspace just got that much more obnoxious.
One step closer to my Iron Man armor. Call me crazy, but the tech is not so far-fetched.
Being serious, your argument is flawed. This might not in fact be a good way to make better solar cells. You can invest as much as you like in technology, but if you try to push too far in one direction too fast you will fail to get synergies. Putting a man on the moon has actually achieved very little for space flight overall. Heavy expenditure on military programs leads to waste and inefficiency, and ends up with paradoxes like commercial semiconductor designs being more reliable than extensively tested military ones.
It actually takes a long time to train PhDs who can build on the work of the previous generation, and the number of people with the capability of doing leading edge work is limited. Before you can spend $300 billion on R&D you have to get a big enough educated population, and that means rapid social development under less than ideal conditions. Don't misunderstand me, I believe we need large investments to mitigate global warming - but the answer may not be solar power, or hydrogen, and it would be foolish to bet the planet on any one technology.

I'm pretty sure this wouldn't work in direct sunlight, as I doubt the heat pumps and solar cells are efficient enough. In diffuse light, which an ideal application of the less efficient thin film cells, it might work quite well. Haven't done the maths though.
Now they've got the semiconductoroff the substrate and flexible, as strained monocrystals, they should be able to align corresponding sites on the multiple layers of circuits to actually go 3D, for more efficient routing. Maybe even rolling up sheets into scrolls. Since they're flexible, maybe rolling scrolls around a power core, making tiny smart wires.

Carbon nanotube networks do this faster and cheaper, have already been used in solar cells, and are being commercialized right now.
