In respect to semiconductor chips and such.

When a vendor finds a problem with a chip, they "re-spin" it - that is, they make a new version of the chip that doesn't have the problem.\n\nDepending on the severity of the problem, it might be a "major re-spin" - changes to the silicon itself, or a "minor re-spin" - changes to the metal layers that connect the devices on the silicon.

they send thousands of tons of old PCs overseas and nothing is done with that material. if you want to get into something worth while get into aluminum. the price of that is real high right now.

I am a circuit design engineer at AT&T.  I have learned that the longer the title…the more useless the job.  (Notice the big guys are CEO, VP, etc…)

Well Blue chip....Well I don't really know much about this amybe try searching it on google.  Search and you will find..

Wise ones go for Computers unless ur in the semiconductor industry

Did you ever stop to think, maybe it isn't microprocessors that are the next step in evolution, but plastics. Our brains are supposed to have 100 billion neurons. We could make a plastic structure with 100 billion interconections (cross-linked polymer molecules) a lot sooner than a chip with 100 billion transistors. So, be nice to plastics-- they might be throwing us out tomorrow.

No, usually the graphic's chip is intergrated unless it's a high end notebook.

THere may be...more info is probably needed, such as the industry or product category.

There is indeed one in development that a researcher used on himself to test out embedded technologies.  There are number of news articles about it (well not really news since it was 1998)\n\nSee sources for links

Very Large-Scale Integration \nVery-large-scale integration (VLSI) of systems of transistor-based circuits into integrated circuits on a single chip first occurred in the 1970s as part of the semiconductor and communication technologies that were being developed.\n\nThe first semiconductor chips held one transistor each. Subsequent advances added more and more transistors, and as a consequence more individual functions or systems were integrated over time. The microprocessor is a VLSI device.\n\nThe first "generation" of computers relied on vacuum tubes. Then came discrete semiconductor devices, followed by integrated circuits. The first Small-Scale Integration (SSI) ICs had small numbers of devices on a single chip – diodes, transistors, resistors and capacitors (no inductors though), making it possible to fabricate one or more logic gates on a single device. The fourth generation consisted of Large-Scale Integration (LSI), i.e. systems with at least a thousand logic gates. The natural successor to LSI was VLSI (many tens of thousands of gates on a single chip). Current technology has moved far past this mark and today's microprocessors have many millions of gates and hundreds of millions of individual transistors.\n\nAs of mid-2004, billion-transistor processors are not yet economically feasible for most uses, but they are achievable in laboratory settings, and they are clearly on the horizon as semiconductor fabrication moves from the current generation of 90 nanometer (90 nm) processes to the next 65 nm and 45 nm generations.

I'll say this much, there will always be structures and structures that need repair/modification and they will always be wherever you are. Electrical infrastructure is one thing that will be around for a long time, but electrical design and electronics design are getting offshored big time. In the 70's thru early 80s my part of the country was huge in defense contracts, then a downturn and tons of EEs out of work. Then telecom boomed and they became "valuable assets" due to the "shortage". Then telecom busted and EEs were on the street again and the recovering is slow in coming. Nanotech is supposed to be the next big thing around here, who knows when it will bust

I have read that future nanotechnology may involve many small machines building small structures.\n\nToday, though, nanotechnology isn't quite that exotic.  For example, lithography is often used in microprocessor production to create patterns on semiconductor surfaces by focusing light through a pattern mask.  The surface is covered by a material called photo-resist that changes when hit by the light.  Then the photo-resist is etched away with acid leaving the very small pattern that was focused on the surface.  Then a layer of material is applied (metal for wire connections, transistor parts, etc).  Many additional layers are required before the processor is completed.\n\nAlso, there are other technologies such as electron beam lithography, molecular beam epitaxy and probably quite a few others.  Basically, it is just shooting a tighly controlled beam of electrons or molecules at a surface to create patterns.\n\nI think there are other areas of nanotech involving chemistry and microbiology.  I just know a few things about electrical engineering nanotech, though.\n\nhttp://en.wikipedia.org/wiki/Nanotechnology\nhttp://en.wikipedia.org/wiki/Photolithography\nhttp://en.wikipedia.org/wiki/Molecular_beam_epitaxy\nhttp://en.wikipedia.org/wiki/Electron_beam_lithography

Gallium based semi-conductor right now is too expensive to deploy. \n\nIf you want completely out of the left field, I'd go for optical processing.

SILICON AND GERMANIUM ARE THE SEMICONDUCTOR MATERIALS WHICH  ARE USED IN THE MANUFACTURE OF THE DIODES AND OTHER ELECTRONIC  COMPONENTS. GERMANIUM COMES FIRST IN THE PERIODIC TABLE WHILE SILICON COMES NEXT.  GERMANIUM HAS LOW CUTOFF POINT THAN SILICON.

What is the question? What do you want to know about the microprocessor? please be specific.

bipolar\n\nSee bipolar transmission.\n\n>One of two major categories of transistor; the other is "field effect transistor" (FET). Although the first transistors and the first silicon chips were bipolar, most chips today are field effect transistors wired as CMOS logic that consume significantly less power than their bipolar equivalents (see FET and MOSFET). Bipolar transistors are available as individually packaged discrete components as well as by the hundreds of thousands on a single chip.\nAlthough the overall market for bipolar junction transistors (BJTs) has decreased, they are still used for high power applications and high radio frequency (RF) applications that reach into the gigahertz range. In the five year span from 1997 to 2002, worldwide sales of bipolar chips dropped from $1.5 billion to $226 million, the latter out of a total semiconductor market of $136 billion.\n\nThe bipolar transistor works by injecting electrons into the "base" (or pulling them out depending on the type of transistor), which causes a non-destructive breakdown in the silicon channel between "emitter" and "collector."
