Smaller Magnetic Materials Push Boundaries of Nanotechnology

IBM is like a sleeping giant who seems to have been forgotten in the gee-whiz of all the i-this and i-that world we live in, but every so often it wakes up and gives forth with some really astonishing new technology, not just a re-packaging of the already existing technology. The implications for things like solid state hard drives is amazing...

Currently, antiferromagnetic materials are instrumental in two different types of data storage products. They are essential for the manufacture of the phonograph-needle-like recording heads used in today’s hard-disk drives. They are also used in a new type of memory chip known as spin-transfer-torque RAM, or STT-RAM, which is viewed by some as a future competitor for both DRAM and Flash memory chips.
Dr. Heinrich said that the tiny devices built with scanning tunneling microscopes would never be more than laboratory experiments. However, he noted that many research groups are exploring different ways of designing novel materials using self-assembly methods ranging from mechanical to biological approaches.
Industry executives said that as the semiconductor industry draws closer to exhausting the ability to scale down today’s circuits using lithographic tools that etch patterns on the surface of silicon wafers, an intense international hunt is under way for a manufacturing technology beyond microelectronics.

:hmmm: All I can say is "good luck with that." The big challenge is getting the litho and etch geometrys to work at that scale. Part 2 of the problem is being able to mass produce functioning chip with that small of an architechture. Sure, I bet they can make a few circuits that small, but to get them on one chip, working and debugging the problems is a whole other beast.:dead:

If you're interested, here some basic info:
http://en.wikipedia.org/wiki/Integrated_circuit


As of 2005, a fabrication facility (http://en.wikipedia.org/wiki/Semiconductor_fabrication_plant) (commonly known as a semiconductor fab) costs over $ (http://en.wikipedia.org/wiki/USD)1 billion to construct,[19] (http://en.wikipedia.org/wiki/Integrated_circuit#cite_note-18) because much of the operation is automated. Today, the most advanced processes employ the following techniques:

The wafers are up to 300 mm in diameter (wider than a common dinner plate).
Use of 32 nanometer or smaller chip manufacturing process. Intel (http://en.wikipedia.org/wiki/Intel), IBM (http://en.wikipedia.org/wiki/IBM), NEC (http://en.wikipedia.org/wiki/NEC), and AMD (http://en.wikipedia.org/wiki/AMD) are using ~32 nanometers for their CPU (http://en.wikipedia.org/wiki/Central_processing_unit) chips. IBM and AMD introduced immersion lithography (http://en.wikipedia.org/wiki/Immersion_lithography) for their 45 nm processes[20] (http://en.wikipedia.org/wiki/Integrated_circuit#cite_note-19)
Copper interconnects (http://en.wikipedia.org/wiki/Copper_interconnect) where copper wiring replaces aluminium for interconnects.
Low-K (http://en.wikipedia.org/wiki/Low-K) dielectric insulators.
Silicon on insulator (http://en.wikipedia.org/wiki/Silicon_on_insulator) (SOI)
Strained silicon (http://en.wikipedia.org/wiki/Strained_silicon) in a process used by IBM (http://en.wikipedia.org/wiki/IBM) known as strained silicon directly on insulator (http://en.wikipedia.org/wiki/Strained_silicon_directly_on_insulator) (SSDOI)
Multigate devices (http://en.wikipedia.org/wiki/Multigate_device) such as tri-gate transistors being manufactured by Intel (http://en.wikipedia.org/wiki/Intel) from 2011 in their 22 nm process.



Last I heard, AMD could bearly handly the 45 nm process (it was giving them a lot of problems, but I haven't kept up with them)

And the use of silicon to base chips on, may be a thing of the past in a matter of years.

Don't worry, they're engineers :03:

God save us all then.:haha:

[nikimcbee]

If you work with one, you know what I'm talking about.:D:haha::wah::dead:

I work with 5 :nope:
But our engineers are engineers on paper only, about as creative and able as a retarded ant :nope:

:har: Let me buy you a beer then. What's your favorite? Most of the ones I work with are pretty good (if you can get past the smugness), but I've been around some real ass-monkeys. It's not that they're dumb, they're just very difficult to deal with.

[Betonov]

Any local non commercial brand ;)

It's their arogance and lost touch with reality I can't get by. Because everything works on paper they think it will work in the workshop. Riiiiiiight, maybe if we actually had the right tools and materials and those idiots would actually be there and see it happen :nope:

The problem is I love a mental chalenge and I love tinkering with new things, but they get the engineers pay and the recognition when things go right :stare:

...and when things go wrong, guess who they point the finger at.:dead: (except when it's their fault, then the problem quietly goes away.:shifty:

[Betonov]

Well, one of the perks at working for our company is that as long as you tell what happened and how it happened, the problem always goes quietly away. No matter who was at fault. There's just too much to do to waste time by pointing fingers. Blame is shared around (for anyone below the CEO)

Take your pick

ahahahahhaa, the Northwestern :haha::haha: good one :DL

But these look like candles, not beer :hmmm:

Okay, the person who found that image has been fired:dead:.

Let's try the non-candle version:

Done. Hopefully, you'll get the beer and not a candle.:dead:

[Betonov]

Just to be sure I'll bring some honey schnaps (not to be mistaken with meadthey're two different spirits) :up:

Riiiight, did we just derailed a science and technology thread with booze :hmmm:
Such offenses should only be reserved for political threads :oops:

OMG you beat me to it.:haha: I was going to post the same thought.


I was going to say, BoT, some of those links from wiki are really good explinations of the current technology.

The big problem witht the ever-changing semiconductor world, is all if the support equipment to build and analyze the new technology.


BTW, if Jim makes it into this thread, you can give him a taste of your beer, but watch out, he'll drink all of it if you're not careful.:03::haha:

[nikimcbee]

So, who or what is driving a good portion of this?

That's good. A company in Slovenia is specialised in such a field. A small star in the darkness of recession :smug:

As long as people think of more complex things to measure, 200 employees will have a job


And while Jim will be drinking my beer, I'll be infiltrating his secret stash :Kaleun_Salivating:

Just found this:
