11. Internet Explorer on a Mac, or Photoshop on Windows?
What about Hendrix on one of those new ethernet Les Pauls, running Linux, responding to nMap as a DreamCast?
Can carbon nanotube be used in CPU production? From what I understand some are conductive with low radiation and others are excellent insulators.
The article talks about "spontaneous electron movement from the negatively charged silicon substrate of the channel to the positively charged gate."
I guess I am just curious as I recently wrote a paper on their applications and I would like to hear from someone a little more technically knowledgable than me. Anyone have any real knowledge or some *easy* links they could share?

between the transistor and an influenza (closely related to SARS) virus, no less.
I don't think it shows the smallness of the transistor as much as I suddenly realized how much further we have to go before hitting biological complexity.
the surface of the virus has crazy number of protein receptors that allows it to latch onto only the proper cells, and inside a strand of genetic material that contains thousands, if not millions of ACGT pairs - which puts information density of our most hardcore RAM at a great shame. Actually there are probably other stuff inside, but IANAVirologist.
Looooong road ahead...
side note: I don't think the gearheads are so obsessed about the manufacturing process for cars, nor the martha-stuart followers the manufacturing process for triple flower-pattern guest-only bath towels, why are geeks sooooo into the photolithography process?
Anybody wants to offer an explanation?

The XBIT labs starts off wrong, and just gets worse. for example, his descriptions of leakage current are all wrong. but, what do we care, we're slashdotters and we don't know our ass from our brain.
Of semiconductors, I think it must be said that Gene Wolfe's New Sun series must be taken into objective consideration when evaluating the potential sociotechnological effects of new developments.
and inside a strand of genetic material that contains thousands, if not millions of ACGT pairs
Actually it's 1501 base pairs (so 3002 bits of information) in one strain of the Influenza B virus.
It's like wiping your ass with silk
Ho, Ho, Ho! Merry Christmas!!
Sorry, that was for just one segment, have a browse through NCBI for the other segments to find out the total size (go on, it's fun :)
YA, YA, ALRIGHT!
No one knows what the hell you are talking about.

I've seen your problem before and I'm sorry to say that no woman will have you. Still you have 2 choices, having sex with animals or other men. Its not such a bad life, just ask CowboyNeal, he is a fat fuck but he often has sex with Rob Malda and Michael Sims, he also has sex with Rob's wife (note: she is a dog, not a woman). So you see there is a chance for you to be happy, just keep an open mind.
I always win, cuz I'm a winner.
Wouldn't biological production techniques (with scalable, repeated simple unit, error correctable systems) be really cost effective?
"... ACGT pairs - which puts information density of our most hardcore RAM at a great shame."
Perhaps; but we can write and rewrite to our "most hardcore RAM" much faster than genetic information in ACGT pairs can mutate.
with my penis. my penis would like very much for you to come visit it.
also, my bunghole.
My guess is that no other industry in the world has the pace of tangible progress as microprocessors (except perhaps magnetic storage). Look back 30 years. Microprocessors were still in their infancy. The product of microprocessors have gotten 10's of thousands of times more powerful. Automobile manufacturing was, however, much as it still is today. The vast majority of textiles manufacturing is similarly unchanged in the last 30 years. History has demonstrated, though, that any fundamentally new technology goes through a very rapid period of development in a relatively short period of time. Eventually, all technologies level off in their pace of development.
Conventional etching uses plasma. Plasma is a soup of charged particles of energy of the order of a kev (1000 electron volts). It's use is mostly dictated by the fact that we understand how to create it quite well, rather than in our understanding of what is/are the consituents of plasma that actually effect the etching action.
What is found that the etching process sensitive to the charge element, to the quantum state of the incident ions, to its energy, to the angle of incidence. And of course this is purely from the beam side, from the surface point of view there are a lot more variables...
Did you know that the molecular process that does etching is very similar to that that creates a radio blackout in the space shuttle while reentry? Somewhat cool
does it run linux?
Jimi wasn't partial to the sound or feel of Les Pauls, he preferred a Strat sound. If he were still alive, he'd have the Les Paul Ethernet wiring ripped out and put in a Strat (since Gibson would probably never agree to do that).
really
Poo is better.
Don't tell me /.ers are busy reading the article...
Seriously, this is one of the best semiconductor physics sites I've ever seen. Informative too.

In this article we take a close look at the contemporary manufacturing technologies used in the semiconductor industry. We tried to raise the curtain of mystery over the transistors and other chips manufacturing process, and to evaluate the prospects of the current and upcoming technological processes.
- Why can't a man fly like a bird?
- The manufacturing process doesn't allow.
Why do car engines consume liters of gasoline in a hundred miles, but not just grams? And why gasoline, but not water? Why is there no portable cool fusion device in every household? And, at last, why do processors consist of just millions of transistors working at a few gigahertz frequency? The answer is very simple: the today's technological process, or the technological capabilities of the manufacturer, don't allow anything beyond that yet.
However, we shouldn't confuse the actual technical capabilities with potential ones. If Intel wanted to produce 65nm processors, they could make them even today, but the production volume would be measured in pieces, or dozens of pieces. And these processors would also cost much more. As we are all living in a big marketplace, we can put it down in the following way: the technological process is a compromise between the theoretically possible level of some technology and the price acceptable for a mass consumer of products made with this technology.
Of course, we see this compromise in the PC CPU market too, although there is some misbalance towards performance prevailing over the price, which is mostly caused by vast and successful marketing campaigns CPU manufacturers have been carrying out. Thus, Intel has been putting about $300 million or even more into promotion of each of its latest processors (Pentium 4, Pentium-M).
But there are sales plans and marketing cycles, there is Moore's law, at last (see our article about Moore's Law for more details). Various economic and marketing reasons, and Moore's law in particular, are a kind of locomotive power for the whole processor industry. By the way, this law, which was originally just a simple observation, but later was puffed up by Intel a little, works now mostly in Intel's favor, because it is most profitable for those who have the highest technological and manufacturing potential.
Besides, the fact that this law was fulfilled so easily didn't do much good to the industry. Engineers didn't have to worry about effective functioning of various processor units: why bother if you could allot as mush transistors as you wanted for every unit. Or at least close to that. Now it has become clear that Moore's law is going to die out one day and such effects as leakage current threaten further development, so, they have finally started talking about a more thorough approach to processor architectures development. This is a very pleasing fact.
Of course, if we would like to talk about the manufacturing technology process used for PC CPU production, we should start with Intel. The company has the biggest production facilities today (25 fabs, at least ten of them make CPUs) and one of the most advanced production processes.

Do you mind, your karma has just run over my dogma.
Besides, photolithography is hella cool.
Reality has a conservative bias: it conserves mass, energy, momentum...
There is an industry with much higher rate of advancement. Since the introduction of disposable diapers, their ability to absorb effectively has outpaced the shrinkage rate for effective processors. Thats one of the little 'facts' we bring up in our intro to engineering classes in materials engineering. Weird, but true.

My knowledge in this field could probably fit in one of these new transitor channels, but I was wondering:
Could the Tri-Gate transitor be a major boon to producing M of N gates with hysterisis? The asynchonous logic proponents would love this. I'm thinking you would might need more layers of interconnects.
Anybody ideas?
if you think this is bad, you should have seen my last sig
this is THE most poorly written article i've actually tried to read on the web in years.
"Besides, the characteristics of the channel become more predictable, while the transistor itself - more robust to various errors, like those provoked by space particles that may get into the channel and ionize it."
i'm not even going to get into the english, which quite frankly is horrid. "robust to errors"? "space particles" (yes i know what he's trying to say)? "ionize it"? ionize the channel? (yes again, i understand he means the carriers, but that's not what happens)
most of his information is unsubstantiated at best. There are no references nor citations. Most of it seems somewhat accurate but only because i understand what they were TRYING to say. If i didn't know about fab tech to begin with i would have been very misled.
If you want to know about semiconductor fabrication technology, do yourself a favor and borrow a textbook from your EE budies, then read up in journals.
