A Glimpse of a Microchip's Delicate Architecture

Computer chips continue to shrink ever smaller, but we still wring more processing power out of them. One of the problems that comes with taking our technology to the nanoscale, however, is that we can no longer see what's going on with them. Computer chips, with their arrays of transistors laid out like cities, have components that measure as little as 14 nanometers across, or about 5,000 times smaller than a red blood cell. Checking out these wonders of engineering without using expensi
