12 inch diameter wafers are cut from an ingot which is a single crystal of doped silicon that’s about the size of a loaf of bread. Circuits are formed on the wafers using 45 nanometer technology.

Silicon wafers 12″ in diameter, although some plants may still use smaller (8″) wafers for some ICs. They come in ingots, which are solid cylinders 12″ in diameter and a few feet long of the purest crytaline silicon: 99.999999999% pure, from a company in Japan. Intel uses a special diamond saw blade to cut up the long “log” of silicon into thin wafers (about 2-4 millimeters thick). .
