Nanotechnology To Replace Conventional CMOS
neutron_p writes "There is a lot of hype around nanotechnology these days, but some things are going to work in a near future anyway. IMEC announced a program aimed at seeking alternatives to the current CMOS manufacturing technologies using nanotechnologies. IMEC will investigate the use of semiconducting wires, carbon nanotubes and spintronics or electron spin." (IMEC describes itself as "Europe's leading independent research center" in the fields of microelectronics and nanotechnology.)
Size really does matter afterall. Who knew?
Faster, cooler chips about a decade from now when the whole chip paradigm has shifted. Nanotech will still have an application, but not as a replacement for current methods. Instead nanotech will be integrated into new manufacturing technology from the ground up.
BLING BLING. Meet the architecture that's changing everything.
Finally an application for nanotechnology that's getting some attention that doesn't involve little machines crawling around my brain and floating through my blood stream.
All the site says is that they are investigating this.
IMEC program participants will investigate the use of semiconducting wires, carbon nanotubes and spintronics and, at the same time, develop the metrology and theoretical approach required as a backbone for implementation of the new methodologies.
I know several other places that have been doing this for a while now. How is this any news at all?
We've heard this all before ... in hard drives! Back in 1999, manufacturers started using electron spin rather than magnetic charge to store data. From the article ... "Magnetoelectronics manipulates electrons in semiconductors via electron spin, rather than charge." Most hard drives today are GMR (giant magnetoresistance), or technology derived from GMR.
So it's not too wild to think that they'll be able to do it in RAM and such as well.
Big IC manufacturers hate adopting radically new and risky technologies before they are forced to. I wouldn't expect CMOS to be phased out for a good while. Remember CMOS logic was designed in the early 60s, but most IC manufacturers continued to use PMOS and NMOS chips until the late 80s and early 90s when the size and number of MOSFETs going into ICs caused far too much power dissipation using NMOS/PMOS...

Acronym overload, please deduct -1 from your Karma and refrain from posting to Slashdot for a 24 hour period.
I want to delete my account but Slashdot doesn't allow it.
GMR discs still store the data magnetically.
The MR and GMR effect only replaces the normal inductance coils in the read-head. While older heads registred a voltage spike because of the magnetic flux change in the coil while the data-layer moved below the head, the new heads have a multilayer material that has a spin-sensitive resistance, so the local magnetic field created by the data on the disc spin-polarizes the electrons IN THE HEAD (nothing on the disc) and thus created a vast difference in head resistance depending on the magnetic field.
So the only difference is in how to get the MAGNETICALLY stored data back... Nothing changed in the storage per se.
HI O WISE PRINCE. WHT TOOK U SO DAM LONG?
Oughta be an "AB" (Anonymous Bigot) category here on Slashdot. Interesting that all those repeated characters got past the lameness filter, though.
The higher the technology, the sharper that two-edged sword.
The term "nanotechnology" is becoming a bit inflated. Companies know that merely mentioning the word nanotechnology in a press-release ensures a lot of extra attention. It is kind of sad that good ol' Slashdot seems to fall for this cheap trick as well.
Not too long ago, nanotechnology was about wonderful fantasies of small machines at nano-level assembling molecules or even medicines. Too bad that simple physics prevent this from becoming a reality (the resistance of air at nano-level is too large, for example). Now, nanotechnology is about punching very small holes in metal.
Maybe it is about time that everyone realizes that nanotechnology is not as exiting as it used to be.
My karma ran over your dogma
For those of us who haven't had their 3rd cup of cofee yet, that would be "complementary metal oxide semiconductor".
You can't take the sky from me...
Wow. That is really bigotish. That is about the worst thing I have ever seen on the internet.
Idiot: most of the chips in your computer use CMOS technology, including your CPU- which is where the problem is developing. We're nearing the limit for size in CMOS, so it's time to look for something else.
Do you even know anything about perl? -- AC Replying to Tom Christiansen post.
Are you sure it isn't engineering staffs being slow to implement the new technology? I don't think companies hate new technology, they just don't like investment risk. They want to be where the profit is, which is being "fast followers". As a rule they like to emulate what works. They want to be sure that the design libraries used in the new technology are debugged and working, whether they design the library or license it from someone.
I work in a university VLSI design group. When our grad students get jobs at the big chip makers, what are they going to do when they get there? The same things they've spent a year or seven learning how to do REALLY WELL: design chips using CMOS for ever-smaller manufacturing processes.
That's not to say they won't have the skills needed to design circuits using electron spin, photoresistive antipolar velocity differential, quantum-based philatelics, or whatever. (Don't look those up, I just invented them.)
The point is that it takes time for design libraries to be built for new technologies. Then the applications engineers convince their bosses to get the design libraries so they can start using them. In the case of a radically different technology, that usually means the boss has to hear that some risk-tolerant company is about to take his sales away by using the newer technology.
Looking back at what you said, I guess you're right. Mod me redundant.
sigs, as if you care.
Nope, Viagra went from lab to marketplace faster than the transistor.
There is a difference between idiots and ignorance. However I do agree with you that the CMOS technology most deffinately is need of replacing. As far as whet it's called .. who cares? Just make it work and work efficiently.
If this happens soon then it'll cause some trouble; colleges generally don't teach nanotech because it's still very much under development. I'm in a program right now that focuses on CMOS integrated circuit design ... am I going to be obsolete before I get out of grad school?
I guess this happens whenever things shift to a new technology, but still, it's sort of depressing.
It's called "biology".
There are several different ways of getting to a functional nano assembler, and one of the current favorites is taking parts of functioning devices (virii and bacteria) and reassemble them into desired configurations.
The only difference between a "nano" device and a virus is who designed it, Dr. Putz or Mother Nature, (Mom built hers using trial and error, lots of "bugs").
When you want something built, come see me. If you want correct grammar and spelling, get a F*ing liberal arts student.
Cool! Now we can have crappy cameras that are even smaller!
So when will the killswitch be implemented?
That's a bloody annoying site. Abstractes that provide little more detail than the Slashdot precis, and no links to sources.
Nanotechnology To Replace Conventional CMOS
Yeaah! Finally!! Cant wait get rid of em Chief Marketing Officers, and their whole stupid feature creating, shrinking deadline mandating ilk...
OH wait.. dang.. its CMOS, not CMOs.. oh well, cant hurt to dream on does it...
There's been a few Physorg stories show up on /. recently, and they've been abstracts of stuff that's old news. I wanna moderate the site down (redundant?).
Seriously; all this talk about nanotechnology, is mostly bunk; we ALLREADY have nanotechnology, most of you are using it RIGHT NOW!
The modern computer processor has bridges that are etched in silicone, a mere 70nm across; that's right 70 nanometers. So instead of saying nanotechnology like it something strange that has never been done before the article should say 'new chips to use nanotubes and spintronix(sp?)'

I was at IMEC last month during a conference (ESSCIRC, held in Leuven, Belgium) and I really thought that they had an excellent group of people with great research topics (cubic centimeter sensor nodes, new embedded RAM, nano-fab, etc). That is until I saw a director PICK HIS NOSE AND THEN SUCK HIS FINGER DRY!! When are scientists going to start researching social skills?
