Let’s get small, redux

Let's get small, reduxIntel is set to disclose some of its plans in nanotechnology, sure to be key to the company’s chips for decades to come. As reported by CNET’s News.com, Sunlin Chou, senior VP of technology and manufacturing, will discuss some of the plans next week at the Intel Developer Forum in San Jose. Topping the topics likely to be covered: Carbon nanotubes and multigate transistors. Nanotubes are strings of carbon atoms tightly bonded together that show promise in manufacturing everything from tennis rackets to electronics. In computer chips, they can theoretically be used to replace the wispy metal wires that now define a chip’s circuitry. That could make processors smaller and cheaper. Multigate transistors, meanwhile, are a way of addressing the conundrum faced by all chipmakers: The more powerful processors become, the more electricity must flow through them. But as chips shrink in size, the extremely small transistors that control this flow are growing overloaded, something like hooking up a fire hose to a Waterpik nozzle, as CNET puts it. One way around that is to give each transistor more than one gate, an approach that IBM is using in some of its products already. Although analysts say they doubt Intel will copy this entirely, the company likely has a similar approach up its sleeve.
