a molecule can act like a silicon chip, when electrons in the orbitals are spinning in their fixed directions. by placing electrons into certain spins, data can be stored like a binary code. thats what quantum computing hopes to achieve; building micro computers.

A microcontroller is a small embedded computer chip. Today's microcontrollers are usually highly integrated, containing memory, clock generators, reset controllers, and I/O devices (like analog/digital converts and UARTs, for example).\n\nOne of the most popular available is the Microchip PIC. However, I like the Atmel AVR which is similar in price and power, but has excellent support for GNU C.

until now i didn't find out the meaning of stepping. but i can tell you for sure that the 90nm structure (technology) is the newer one. 130nm is the older technology.\nnm = nano meters (10^-9 meters), this is the structure width (thickness) of the conductors inside the chip.\n\nbtw, Intels latest processors already use a 65nm structure.

Not yet. All life WE know is carbon based. Try to find speculation on silicon based life, for a start.

The most recent issue of IEEE transactions (2006, v.14, issue 4) is devoted to VLSI. The major specialization areas it cites are: systems specifications, design and partitioning, high performance computing and communication systems, neural networks, wafer-scale integration and multichip module systems and their applications.\n\nBesides the articles in this journal, there are a number of websites detailing VLSI conferences, journals, and professiona organizations. I would look through these sources for "State of the Industry" reports. Wikipedia and IEEE maintain a list of up-to-date links: http://en.wikipedia.org/wiki/Very-large-scale_integration\nhttp://www.ieee.org/portal/pages/society/eds/technical_committees/vlsi/links.html

I'm not sure about cars in our pockets, but nanotech is already happening, and yes it is changing our lives. In its simplest form, materials tailored at the nanolevel (a primitive nanotech) are already in stores. Nanomedicine, especially lab-on-a-chip technology is partially available and promises to revolutionize the way we do medicine. I don't know about some of the crazier promises (smart fog and such), but research at the nanoscale is changing our lives and will continue to do so.

I'm curious.... If it's due tomorrow, how long have you had to research it?  In any case, you are in luck!  This is the technological age and you can GOOGLE IT!\n\nBest Wishes,\n\nSue

That's what makes a computer (silicon computer chips)\n\nit's called "silicon" computer chip not because it's silicon but because the semi-conductors (transisters) are planted in silicon (it's just the way they build them now to make them so small)\n\nEvery computer including the one you're on, Xbox, Printers, your cellphone, even calculators, etc... anything that is computerized has that chip in it.\n\nIn your computer you can find it on the mother board, it looks like that...\nhttp://www.enviroliteracy.org/images/page-spec//silicon-chip.jpg\n---it's about the right size too.\n\nThey are used to process the information, it's like your brain. It's the brain of the computer,it tells everything what to do, that's what makes everything work!\n\nWithout them, the computers will be huge (like a city block huge) Just like the ones people first built (with a bunch of wires and crap)\n\nAt the link below, you can see various silicon computer chips...\nhttp://images.search.yahoo.com/search/images?p=silicon+computer+chip&sm=Yahoo%21+Search&fr=FP-tab-img-t&toggle=1&cop=&ei=UTF-8\n\n\n\n\nAnd just a little extra for your school project...\nThis is how they make those silicone computer chips...\nI have a friend that works there, he got me one of the unfinished products (it's a shiny disk that's about the size of a waffle) It has like 100 of them on there and they cut them out with a microscopic water stream!!!...\n\nhttp://radio.weblogs.com/0105910/images/3dchip.jpg\n\nhttp://www.intel.com/education/makingchips/index.htm\n\n\n\n\n\n\n\nCheers!!!\n\n\n\n\n\n\n\n\n.

Conductors and insulators are only building materials that provide the means for directing data from one point to another. The functionality of manipulating data comes from the special properties of semiconductors, which can be made to amplify a signal (i.e., a variation in voltage). \nWhen connected together, two very simple amplifiers (possibly as simple as one transistor each) can make a bistable circuit, one which always has one transistor conducting and the other cut off. These bistable circuits, called flipflops, can store one binary digit (bit) of information: one state, with transistor A on and B off, is considered "0" and the opposite state is "1". So a single flipflop can take the role of one bit of memory. A flipflop can be triggered to go from one state to another. When connected so one flipflop's change of state in one direction (say from 1 to 0) triggers a change (from 0 to 1 or from 1 to 0) in the next flipflop, you have the beginning of a binary counter. Similarly, flipflops in other connections can form arithmetic registers, in which two binary numbers can be compared, added, and otherise manipulated. Building on these simple forms, complex logical and arithmetic functions can be implemented.\nThe above only describes digital circuits. Semiconductor amplifiers are also used in analog and hybrid (part digital, part analog) microcircuits.

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

If it's on optical mouse, you may need to put it on a different surface. Optical mice need some sort of visual detail to track, like dots or wood grain or lines or something of the sort. They don't work well and will "skip" like that on shiny, or completely blank surfaces.

they are multi layers starting with silicon chips to which a thin film of metal either aluminum or copper ( hence coppermine CPU) next a photgraphic process that places a film on the metal, then an etch to remove the unwanted metal, then other layer fo metal til the final design is made then, tiny wires are soldered to leads with a microscope, all and all it is very interesting, in the begining the yeild was low but is much better today

Molecular nanotechnology ("MNT") is an anticipated manufacturing technology that would allow precise control and positional assembly of molecule-sized building blocks through the use of nano-scale manipulator arms. Molecular nanotechnology is usually considered distinct from the more inclusive term "nanotechnology", which is now used to refer to a wide range of scientific or technological projects that focus on phenomena or properties of the nanometer scale (around 0.1-100nm). Nanotechnology is already a blossoming field, but molecular nanotechnology - the goal of productive, molecular-scale machine systems - is still in the preliminary research stage.\n\nNanotechnology was first introduced in 1959, in a talk by the Nobel Prize-winning physicist Richard Feynman, entitled "There's Plenty of Room at the Bottom". Feynman proposed using a set of conventional-sized robot arms to construct a replica of themselves, but one-tenth the original size, then using that new set of arms to manufacture an even smaller set, and so on, until the molecular scale is reached. If we had many millions or billions of such molecular-scale arms, we could program them to work together to create macro-scale products built from individual molecules - a "bottom-up manufacturing" technique, as opposed to the usual technique of cutting away material until you have a completed component or product - "top-down manufacturing".\n\nFeynman's idea remained largely undiscussed until the mid-80s, when the MIT-educated engineer K. Eric Drexler published "Engines of Creation", a book to popularize the potential of molecular nanotechnology. Because MNT would allow manufacturers to fabricate products from the bottom up with precise molecular control, a very wide range of chemically possible structures could be created. Since MNT systems could put every molecule in its specific place, molecular manufacturing processes could be very clean and efficient. Also, because every little bit of matter in an molecular nanotechnology system would be part of a nano-scale manipulator, nanotechnological systems could be far more productive and maintain much higher throughputs than modern manufacturing techniques, which use macro-scale manipulators to fabricate products.\n\nTo initiate an MNT revolution would require an "assembler" - a reprogrammable nano-scale manipulator capable of creating a wide range of molecular structures, including a complete copy of itself. The first assemblers will only function effectively in lab-controlled environments, such as a vacuum. The advent of self-replicating molecular nanomachines could quickly lead to "desktop nanofactories", tabletop appliances that consume modest amounts of power and contain the software required to manufacture an interesting range of useful products. The arrival of MNT would revolutionize wide sectors of human activity, including manufacturing, medicine, scientific research, communication, computing, and warfare. When full-blown molecular nanotechnology will arrive is currently unknown, but many experts foresee its arrival between 2010 and 2020.

Moore's law is the empirical observation that at our rate of technological development, the complexity of an integrated circuit, with respect to minimum component cost, will double in about 18 months.\n\nThough this is merely based on observation (there is no overlying principle that might support it), the implication would be that computers will eventually exceed any possible use we could have for them (imagine a 100Ghtz processor in your computer). Of course, the same argument could have been viably made 10 years ago and we've continued finding uses for increased processor speeds since then.\n\nI can envision with the next twenty years or so having computer games that produce nearly lifelike graphics rendered in real time, and that would certainly require greater processor speeds...

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.

That's a tall order.  If I had a spare 18 hrs I'd love to, however...\n\nThere's a chip that does it.  Its called an Arithmetic Logic Unit (ALU).  Here's some suggestions:\nhttp://www.xs4all.nl/~ganswijk/chipdir/f/alu.htm\n\nNo offense, but its a ton of work, with no assurance I'll get my 10 points.

Its resolving power is around 2 nanometers (two millionths of a millimeter).\nIt can detect proteins and other small molecules. \nBut atoms are much smaller than that, and can only be visualized by atomic force and tunnel effect microscopes, which use a very fine tip to probe surfaces, and react electrically to the atoms they encounter. But they don´t actually render real images, but instead an artificial computer-based reconstitution.
